Tire Review: Cooper Discoverer S/T Maxx

[@chloehennessey6813]

Cooper Discoverer are used a LOT in Alaska. Especially where gravel and logging roads are prevalent. You just can’t beat they’re reliability.

[@fredrickfoster6564]

I gotta agree I put many many miles on mine in a 35 towing my fifth wheel and mild offloading. The compound is very hard, but mileage and durability is amazing. I have a bug cut near the tread from when I got hit and went in a ditch and its held up and not lost air.

[@mrdan1990]

Your review just reinforced my wanting to get these for my truck. Two tracks for hunting,going to to silver lake sand dunes and daily driving to work. Sounds like they're well rounded,no pun intended, to cover all the bases for me. Thanks for the review!

[@thefordmaniac]

Thank you for staying true to your roots. I wish motor trend and roadkill and the tons of other no longer free to watch shows the best of luck. My son is disappointed that he won't be able to watch them anymore.

[@TheDavidFreiburger]

thefordmaniac He can watch them free at MotorTrend.com

[@thefordmaniac]

David Freiburger totally free or free for a limited time no one can give me a real answer. Thanks for the reply david!!!

[@kanoandlupo3707]

thefordmaniac some episodes are locked to subs but you get a week free I signed up it's awesome like Netflix for gear heads so much stuff on there

[@tardis4229]

Not in Australia we can't. twitter.com/MotorTrend/status/976216989965406210

[@lucasmastandrea5774]

thefordmaniac they are free just like youtube but if you pay then you get the next episode early before its released for free

[@BenLeBlanc1]

Throwback style vid to KZbin 4 years ago... haha. Keep up the good work- you’re a living hotrodding legend, and I look forward to seeing what choices you make.

[@WheatSn4ckBread]

Would love to see you upload some of those trips with the TJ. Kind of like the videos you and Mike did before Roadkill.

[@andrewkennedy9704]

WheatSnackBread I think that would rule.

[@mattferguson439]

I have been going back and forth between these and a couple other tires as to what to get next month and I think you sold me. I've followed a lot of your shows and your description of use for that jeep sounds like what I'm doing a lot. I think I'm gonna give them a go!

[@DrewEdwardBacklas]

I have these on my 1/2 ton Chevy 4x4 daily driver that sees occasional family overland-esq camping trips and I've been pleased with them. Now you validated my opinion and made me feel all warm and fuzzy inside.

[@CoastalAutoReactionCAR]

It is awesome that you are taking the time to upload videos here. Thank you.

[@tself77]

Let's hear a review on those new Bilsteins!

[@jonnoMoto]

Now that roadkill is dead, you should do a collab with this other KZbin channel, I think the guy is called Mike Finnegan

[@himynameisluis13]

jonnoMoto i feel David fears that roadkill is dying

[@goprowhiteboy]

It is still free on mt.com why is everyone crying

[@jonnoMoto]

😭😭😭

[@neverstoplearning7214]

Wait? What ?!!?

[@onemat2000]

What? I watch it all the time! David.love that you are still running a TJ. I have an 05 and people in the HIs always snicker. I don't know why.

[@MrBluoct]

Great to see two door jeeps anywhere these days Too many 4 door “overlanders” heading off to picnic locations

[@keetoniswhat]

Loving these Jeep videos. Really appreciate the knowledge and time you take to make them.

[@redoakranch1783]

I had these and agree with your review. Mine developed a crack at the low pressure fold area then about 3 months later it cracked all the way through and failed, while sitting in a parking lot! Moved on to Nittos since.

[@T4nkcommander]

Pretty much decided these will be my next tires for my Raptor. Been disappointed with the factory KO2s. Thanks for the video!

[@CLGravy]

Nice. Please keep a YT presence Dave. The best part of RK and MT before Discovery bought it is the plain, no frills, straight forward goodness of it. A lot of us fear that RK and our favorites (even though still free on MT.com) will quickly turn into over produced docudrama. Not hating at all, I get that things change and business stuff happens, but a lot of people took it very personally when comments were disabled for vids and everything was pulled from YT. Anyway, good to see stuff like this. Just a plain jane video of a legit car guy talking tires. I'll watch a hundred of these.

[@neverstoplearning7214]

Chancey Graves so true !!

[@TheDavidFreiburger]

Chancey Graves So far no one has asked us to change the style of our shows

[@arthurbothamjr8104]

David, break out all the junk in your wrangler and show us what you carry on 4x4 trips.

[@shitbox7413]

Good to hear they wear well, I’m a fan of Cooper tires, ran many of them over the years, but have found they wore easily. Obviously cooper has upped their game. 👍🏻

[@edt11x]

I am always amazed at the breadth of your knowledge that you can just stream out!

[@mostlypostie1]

Great review! FYI - I'm hoping we see more content from you here David! I follow you and Fin on KZbin and to be honest, you guys (as well as Lucky and Tony) ARE youtube for me. Best of luck in the future to you all the guys, and I hope we see more of you guys in places like this!!! RIP Motor Trend! And - G'day from Australia.

[@jasonivers9414]

Glad to see your pushing out your own content!

[@ktrudeau340]

I'm with you Dave, I'm noticing that all the new 3 ply sidewall offerings lack a transition from tread to sidewall biter that made the old MTZ and Baja Claw radials so good. Maybe it is just a visual but In my mind it seems like it would lack aired down sticky goodness.

[@GoodsDell7]

I have those tires on my Hummer H3. They are excellent off-road, but a bit noisy on the highway. Overall, I like them a lot. Thanks for your review.

[@JeepnJeff]

I'm surprised you're not running 15x8's which are more popular here in CA. I agree though, those tires do look weird. I run 33x10.5 KM2's on 15x7 OE wheel. Good compromise for street and offroad. Not to mention I'm a fan of the skinny look.

[@SKIPWIRE1]

David you've got more integrity than Motor Trend. Why? You are allowing commenting. How does a brand survive when they don't allow commenting? Oh, yah, they don't.

[@goprowhiteboy]

SKIPWIRE why would a brand not survive without commenting? Many brands do not have KZbin comments and are doing just fine

[@andycocchia4202]

they do have commenting

[@nathanboyles6222]

Why are we giving him shit? I’m happy watching this without bringing up mtod all day

[@keetoniswhat]

Not sure what you're talking about...just watched the newest Junkyard Gold...definitely has commenting available.

[@jonalan7723]

I run these exact tires on my 2001 f150 4x4. They preform outstandingly well for me. When i got 7” of snow and all the roads in my town were completely iced the truck preformed likes it was near dry pavement (at sensible speeds of course).

[@braedon.builds]

I could listen to you ramble about anything all day, review more things we need your knowlege!

[@georgehenderson2315]

David, Thanks for your interesting review. You note the smooth sidewall is prone to cutting damage. I suspect the relatively wide wheel rim on the jk may be wider than recommended by the maker for that particular tyre size fitted. Suggest a slightly narrower rim might permit the smooth sidewall to 'hide' somewhat allowing the side biters first contact irrespective of inflation pressures. I do not imagine a change of rim would entirely prevent the possibility of damage but reduce the opportunity. What do you think?

[@tittledieselperformance]

Used that tire on a customers ram 2500 diesel, there well mannered all around. If your a mud guy it's ok but not great, snow, rocks, street, road noise are all great. It's nice to have a growing market between a AT and MT. I'm a die hard MT fan but now and then the road noise gets annoying so these fit the bill. I change tires constantly too, a recent one I'm overly impressed with is the mastercraft MXT in a 285/75/16 on a 95 ram 3500 SRW diesel . There quiet for the aggressive pattern and handle all day to day terrain with ease. Maybe after the coopers are trashed give the mastercrafts a go. Thanks for the vid David

[@whatsongisthis5691]

These reviews are great. I wish you could do a whole slew of off-road tires. I would watch all those videos.

[@arfiyuriskiawan]

Cooper are good tires. I'm running the Cooper Discover AT/3 255/75/17 Running them on a lifted WJ . Quite. Taken them in the dirt so far so good.

[@xjcory55]

Love that Jeep! It's set up so well, especially as a multi-purpose vehicle.

[@Durmarsa]

RIP Roadkill

[@LoganC1988]

Diesel Specialties Its not going anywhere.

[@fourutubez7294]

Its been flushed down the Murdoch shithole along with some other things on motortrend that no one cares about

[@kanoandlupo3707]

Roadkill ain't going anywhere bud

[@keetoniswhat]

Everyone whining is just too cheap to support it. I remember having to buy entertainment at one point. There was a time when everything wasn't free.

[@HoosierDaddy_]

Thanks for the review. I've been thinking about these tires for awhile but I just can't seem to commit. Something about these tires is just a little off.

[@birdsnestfishing698]

Thanks for the review I have been looking for some tires like this for my 04 f250, I have 35” k02s now that I love but have been looking into new wheels and these were on the list.

[@stevethomas7463]

Did you buy these tires? If so, how were they?

[@mccatdaddy]

Iv got the same tires on my f350 7.3. 33/10r17. Load range e. It’s a 7000 pound truck, and iv got 25k miles on them so far, I should be able to hit atleast 50k miles on them before they get too low. I don’t put the truck is much mud, but I can say these tires are great in the snow, when I buy 20 inch rims, I’m getting these in 35s. My favorite tires so far

[@RoadkillJTA]

These were my second choice when looking for tires for my Silverado, I ended up going with the Cooper Discoverer STT Pro. Now that I have them I think i'll be trying out the S/T Maxx tires next seeing as I'm not offroad as much as I thought I would be

[@KTMSparky]

Any further comments? I'm torn between the maxx and the pro lol

[@jeepcollector91]

Thanks for the review. Keep this great KZbin content coming.

[@isaacitzkowitz4755]

Post videos of your camping adventure with your son. Keep the videos coming love them

[@lostonlongisland6845]

awesome video as usual..always love when you and Finnegan put out videos..i just wish you two could do something together and keep the corporate b.s. for gasmonkey. even though we feel a little cast aside your fans are still behind you. r.i.p. motortrend but roadkill will live forever

[@zwlewis87]

I’ve had these for around 15,000 miles on a 2007 JK Unlimited and have been running about 28 psi on the street. I absolutely love them. They’ve mainly seen road use and have only lost about 4/32 of tread in 15,000 miles. At this point I think they might dry rot before they wear out.

[@jz3430]

Great review. I had the same feelings about the sidewall design!

[@64_Falcon]

Thanks for the upload. Love your jeep

[@davidwayne9982]

THAT sounds good.. thanks for the review-- sounds like you run pretty much like I WILL and do.. and I'm trying to decide between these and the KO2s.. but I think I like these.. Kos are nice-- but they still look a bit tame to me. I see what you mean about the PEAK on the side.. but I won't do that much with them offroad anyway-- NOT INTENTIONALLY-- and winter is another concern.. but I think these are Peak rated for that too..

[@reubenfox6357]

When is the next episode of roadkill going to be on KZbin? It's been over a month

[@BustedWalletGarage]

Reuben Fox you haven't seen the news ? Will only be available on MotorTrend On Demand. I've had an account got 1-1/2 years. About time they did this.

[@BustedWalletGarage]

Stuka87 this morning they made an announcement that it was all going to be exclusively on MTOD

[@Stuka87]

Yeah, i removed my comment as I saw that video just after this one. Even then, $3 a month to support something you love? Big deal.

[@TheRealSmithFamily]

I paid 90 bucks for 2 years of MTOD and that includes a TON of Velocity shows as well as MTOD originals. That comes out to 3.75 per month and IMO is reasonable.

[@BustedWalletGarage]

4gasem they screwed up my bill & overcharged me. The billing department is contracted out and took about 6 months to get it corrected ( my bank had to threaten them ).

[@turtle2448thomas]

I have the Cooper Discoverer STT Pro on my F150 and I love them! They perform great on the highway without too much noise for a M/T, but perform better than any M/T I've ever owned!

[@TheDavidFreiburger]

turtle2448thomas I agree, those are really good

[@thealmightywalrus5404]

I don’t know how much knowledge you have on this type of swap but I’ve been pondering lately about swapping the whole drive train from a TJ to an XJ. I like the looks of the XJ but I want the capability of a TJ. Also the manual six speed. Is it possible for all the driveline, such as the axles and transmission and transfer case? I can see some issues with driveshafts being short but couldn’t the regular XJ driveshafts work?

[@Low97ss]

How do you like the new shocks?

[@jamessimpsoniii2029]

had these tires for 3 years and Cow mountain is passable in them as that were I think you are. haven't taken them up the pass in snow but the should do as well as the old Yokohama at that lasted a decade

[@KaiserMeadWorksSpokane]

Great review!!

[@lilorbielilorbie2496]

Hey David what,s the deal with not being able to read/leave a comment on Roadkill/DirtEveryDay videos here on you-tube.? also has Roadkill the magazine been killed off, or is it still going to be published.? if not how do i get a refund for my sub.?

[@baronsable6173]

They most likely don't wanna see all the back lash from they're latest upload........even though social media is blowing up lol

[@MrMrsregor]

sadly they seem to have stopped making them. they are still for sale on the internet, but i could not find a cooper tire dealer that could get these...i have these on my truck and love them, but ended up going to the cooper stt pro since for my jeep since st maxx was not a choice and i think i do like the stt pro more..

[@MrMrsregor]

They are still available. They were just hard to find while Cooper tire was being bought out by another company…

[@johndorflinger2344]

I like narrower wheels, it brings the scrub radius down and holds a bead better when aired down. Do you ever get the "death wobble" with them?

[@TheDavidFreiburger]

John Dorflinger Never had death wobble on this Jeep. I keep all the bushings in good shape.

[@johndorflinger2344]

Thanks, I love your shows.

[@lilorbielilorbie2496]

how soon will it be before mtod makes Freiburger and Finnegan put their own channels on mtod.? the countdown has begun.

[@jessebarta8195]

I have been looking at these to put on a dentside f100 2wd work truck. Just need something a little more durable than a regular all terrain. Do you think they would work well in a more narrow size? I see you have a pretty wide setup there that won't quite fit the truck.

[@beerhunter272]

I own these tires in a 10-ply and I LOVE them. They perform awesome in all conditions, they ARE quiet and they don't grab and throw rocks like you'd expect. They are a commercial grade tire and after over 35000 k on them, they look just about as well as when they were new. They are much less expensive than most off-load tires as well.

[@neverstoplearning7214]

But how are they in the cold and Snow/ ice ???

[@mattferguson439]

NeverStopLearning no idea how these specific ones are in those conditions but I can tell you that the Cooper Discoverer M/S tires are wonderful on snow and ice. I change my tires between winter and summer and run proper winter tires in the winter. The M/S version of these is a little less on the tread (it's still got a bunch) but they are excellent in deep snow and on ice. Temperatures where I am get down to -30 Celsius in the winter sometimes and those tires are solid.

[@fredrickfoster6564]

On a heavy truck ( 07 classic duramax weighing 8500 actual) they do good because of the weight. On a jeep or Toyota not as great the tread compound is made for heavier vehicles.

[@adamfrbs9259]

Nice...i had same jeep but the anniversary edition. Those are the tires i wanted. Ended up trading it in last year on a 2014 SS Camaro.

[@turbolq4]

I have these on my F250 Powerstroke. They are very good and I would buy them again.

[@ronsmith9251]

Thanks for uploading this video. I think Cooper makes a good tire.

[@oldssmoky]

Do you notice that it pulls to the right on paved roads? I have read that they do and I have a set that does.

[@TheDavidFreiburger]

oldssmoky No. I can’t even think how that would be possible.

[@kevinthomas895]

You might want to have an Alignment specialist check the caster angles.

[@oldssmoky]

I HAD A GOOD SHOP GO THROUGH THE WHOLE FRONT END AND REPLACED ALL THAT NEEDED TO BE. IF YOU LOOK UP COOPER ST MAXX PULLING PROBLEM THERE IS A FEW THREDS THAT SAY THEY PULL TO THE RIGHT. THEY HAVE HAD THEM ALIGNED MULTIPLE TIMES AND ROTATED WHEELS TO DIFFERENT SIDES. WHICH I HAVE ALSO HAD THEM DO AND THEY CAN NOT FIGURE OUT WHY OTHER THAN THE TIRES JUST DO THAT. SOUNDS DUMB BUT I GUESS IT JUST IS WHAT IT IS.

[@TheRealSmithFamily]

How so? I just watched the new one on motortrendondemand.com.

[@JimnyVR5]

Me too, but without KZbin they are going to lose so many viewers... which probably doesn't matter if the money is right.

[@thewakz]

LOW BUDGET shows, 12 episodes a YEAR, most had SPONSORS and almost 7 MILLION subscribers FAILED? It must be rough out there. If they can't make money with that, MT is doomed.

[@eljefe3497]

Absolutely not trying to be a hater here and some will no doubt disagree, but I’ve run many many mud and all terrain tires on many different vehicles.These exact tires were the worst I ever had. They had no traction in rain snow and ice. I referred to them as crappers.

I was talking to my friend about corollas like Freiburger talks about stuff. I was describing the minor changes on the tail lights between a 94-95 and 96-97 corolla. And the facelift of an 8.5 gen corolla.

[@aaronzawadski4496]

Wow Freiburger I'm completely disappointed in the roadkill sell out! I understand the motor trend deal, but to forget why it exists and pull it from KZbin is a terrible decision. The fact that they had to disable comments is proof of that.

[@rcairforceone]

David Freiburger Thanks for the quick reply. I had C load range AT3s on my lightweight TJ, and they worked pretty good (though it's worth noting the terrain and trails where I'm at are not challenging.) I've got a FZJ80 now on BFG ATs, and I want to upgrade to a more aggressive tread without going with a gnarly MT.

[@kurtseyffert6649]

seems stuped why cant they do like others and treat demand like there patreon and still upload to youtube

[@grizz3332]

Yeah i agree , but it's all down to discovery buying the network without that nothing would change , but things cost and i think it was just a matter of time even without discovery buying the network until it went fully MTOD , hopefully the guys may start on their own as it might get more corporate than it is already and the program might change too much i would rather pay into whatever project they do via patreon than a MTOD subscription.

[@alantrimble2881]
