TeraFlex Tech: Choosing Tires For Your JK

[@teraflexsuspensions]

A 35" tire and 2.5" lift kit is a great starter combination for any new JK. The 35" tire is a very good size tire for a JK. TeraFlex has a 2.5" BB and a 2.5" coil suspension option for you. Both will work great for what you need, the BB kit will be lower cost vs the 2.5" coil kit will raise the front 3.1".

[@VideosClassAct]

You guys are hilarious! Loved the video. And I gotta say...no one has EVER explained tire sizes better than you did in this video. Thank you for taking the time to educate us on tire sizing and explaining what the sidewall numbers mean. Very helpful. Kudos!

[@gmangsxr750]

I really REALLY like your videos especially when you show the range of options side by side like you do with the tires in this vid or the jeeps in the lift vid. Very helpful to see them all together. Thank you!

[@lolite_a]

I’m a new jeep owner and I know this video is old but I love this! So informative and funny

[@fletcherbrown728]

Excellent tire education for me. This really brought it all together. Thanks for the hard work. Next video we need to hear more from Jen. “Tires are big” made me spit out my coffee as you caught me mid-sip.

[@DieselPowerProducts]

Hilarious as usual. It was nice meeting you both at EJS. We just became the official retailer for the Ultimate Adventure. WoooooooooHooooooooo! Let's sell some TeraFlex!

[@AussieFourWheelers]

Hang on!!! at 2:00 the tire profile explanation is wrong. 60 or 75 (etc etc) for profile is the "aspect ratio" of the width. So it is incorrect to sat that a "60 series" in this case would be wider than a "75 series". There's no series here, it is the aspect ratio of the width in percentage. Regardless if the aspect ratio is 60 or 75 (or whatever), the width will always remain the same, if it's 255mm it'll stay 255mm regardless of the aspect ratio (profile) but the profile of 255 and 275 with the same aspect ratio (say of 75) will be different as 75% of 255 and of 275 is different in mm or inches.

[@jaymanxxxx]

the first number it as important as the second ie. 60% of 255 is less then 60% of 285. so the width of two 60 series tires is not be the same unless all size numbers are the same.

[@AussieFourWheelers]

jaymanxxxx That's right, but it's not what he's saying in the video at asround 2:10

[@jaymanxxxx]

true.

[@splewy]

Yeah exactly, this guy's explanation is wrong. The first number is the only one that governs width. All 255 tires are the same width. All the second number determines is sidewall height. So a 255/60 would be 255 millimeters wide, with a 153mm tall sidewall, and a 255/75 would be 255 millimeters wide with a 191 millimeter tall sidewall.

[@tacraheennc9719]

What size rims should I put on the 35 inch tire

[@bryanfrasher6556]

I have been researching wheels and tires for my Jeep for about 2 months now and this is the most entertaining and informative video I have seen. Thank you...... btw, I went with the 35's.

[@shadley673]

Just curious: Did you end up having to re-gear when you moved up to the 35s?

[@teraflexsuspensions]

A 2.5" lift with a 35's looks great! The 33's might look a little small in there. Get your tires under your JK and drive it for a while before you decide to do a gear change.

[@teraflexsuspensions]

You can upgrade your front axle shafts to RCV axles or another brand of chromoly. The stock rear 44 shafts are really not bad and do not need to be upgraded as much as the fronts. However you still can swap out the stock shafts for a upgraded version or just install a Tera60 rear axle.

[@eddiesoltys9586]

Did anyone else see see at 1:26 he hit the tire and she jumped away like she was expecting to get hit

[@teraflexsuspensions]

When I asked Jen if I could " hit her up" for some help, I didn't think she would take it literally. HeeHee...thanks for watching our lame antics. Dennis

Thank the lord I ran into this video, I’m looking to buy 35” tires and I have absolutely no clue what the heck I’m doing. This just explained everything, I understand now. Thank you!!

[@aricrla]

I don't know if it was part of the comedic aspect of the video, but at 2:21 the picture of the "Radial Tire" is actually a Bias tire. I love Teraflex suspensions and the videos are a good watch.

[@teraflexsuspensions]

Yes it is different for a TJ, maybe we will have to create a TJ specific tire video also.

[@rc-hc1zv]

Really great video. The time and dedication of edit and quality is appreciated!!!

[@teraflexsuspensions]

Depends on what motor you have. With a 3.8, go with 5:38's, 3.6 you can run 4:88's.

[@teraflexsuspensions]

There are 1" and 1.25" wheel spacers available for the JK that you can use. Otherwise you can run a new wheel with 4.5" -4.75" backspacing.

[@lindsayscottyoga]

I'm so glad I found this video! I just got a Wrangler Unlimited and want to make some changes as soon as my wallet allows it. My past 3 vehicles have been cars and I've never made any changes, so I am a total newbie. Although I have no experience with any of this, I am so excited to learn, and this video was a great start!

[@JosephDowski]

Lol me too! Just finishing my second week of Wrangler ownership.... Overwhelmed is an understatement. Thankfully I'm about out of money for the time being so I will have time to learn more before making enhancements... At least the Jeep Wave is free... :)

[@MIKE192rotary]

If you don't plan any mods on your jeep... Turn the video off. Best advice I heard so far!!!!

[@teraflexsuspensions]

You can run 33"/34"/35" tires with the 2.5" series.

[@amann330]

I've been debating 33's or 35's on my 09 JK and this video helped me make my decision. 35's. I had previously been told that 35's will kill MPG and driveablity but it sounds like that's not the case. I'm running a 2.5 inch lift and considering adding a 1 inch body lift when I buy the wheels. I do plan to take it off road quite a bit and have already done so prior to the mods I'm making.

[@trikeman2k]

I am a new Jeep owner, this has been very helpful.

[@MadOgre]

If I was still in Utah, I'd have to stop by just the shake Dennis's hand... just because of this video. Classic.

[@billyhawkins5222]

Thanks for making this video! It was very informative and funny as all get out!! We just purchased a 2016 Willy's with the stock mud terrain tires and we love it but definitely going to the 33's when they wear out.

[@teraflexsuspensions]

You can run a TeraFlex 2.5" -3" lift with 35's and still run your stock gears.

[@Mr.Bearded.Mechanic]

A small add for metric tire sizing. If we stay at your example 255/75, 255 is the width of the tire in millimeter and the 75 is the percentage of 275 that gives the height of the wall. 255*0.75=191.25 mm. Nice video!

[@wheresrobthomas]

This was great, I know it’s older but the info here holds up! I run 35” MT Baja Boss on my 2015 JKU and love em

[@teraflexsuspensions]

Right on!

[@teraflexsuspensions]

Running coil overs is never cheap and sometime requires a lot of modifications. Plus cost is a big factor. With coil over you are able to dial in your suspension more than when compared to a non coil over setup.

[@teraflexsuspensions]

You can run a TeraFlex 4" kit with 37's no problem with stock flares.As far as mpg's, it really depends upon how much you mash the gas peddle. You might lose 1-2 mpg's with the 37's.

[@oldmanjeepingandbiking9621]

I'd like to invite you to SHUT THE VIDEO OFF RIGHT NOW! OMG, laughed so hard

[@northcountry4x473]

We are running a 2" lift kit on our 1999 Wrangler with 32"s. So far so good!

[@lumbermike]

Man Dennis, I wish you guys would cater to the TJ owners. You put out such great videos.

[@CnRDirt]

@cpn2285 that's the kraken built by cop4x4. It's a 54x19.50r20 on custom suspension with teraflex long arm of course

[@PappaKosta]

How could you dislike this! It's very well done!

[@andrifsig]

I would always recommend minimizing the lift of your 4x4 vehicle. We run a Toyota Tacoma on 44" tires with a little over a 2" lift. We used to run it on 38" tires with no lift. It keeps the center of gravity lower and makes it easier to use. The tires do not rub into the body, because we do some extensive bodywork to fit the tires. It is worth noting that we are in Iceland where we drive in snow when we are offroading so ground clearance because of rocks or boulders is a lesser issue. We encounter that kind of terrain on occasion, but for the most part it is trying to get a wider footprint on the snow so you don't sink as much in it. The modified cars here in Iceland range from lightweight cars on 33" or 35" tires (that is considered small here) to 54" behemoths. Most run on 38" to 46" tires. Anything smaller than a 38" is fine for a day out in the mountains during winter, but you need bigger tires if you are planning for a trip for the weekend, unless it is really light vehicle. I am thinking Suzuki's here.

[@homesaverchimney]

I run BFG LT315/70R17's with a 2.5" JKS suspension lift on my 2 door JK. Tires are extremely quiet and excellent off road. Very durable as in long tread life. I plan to replace them with the exact ones when the time does come.

[@DABEARS500]

Great video! One thing you didnt mention is steering components need to be changed with larger tires. For example running 33's with a stock power steering set up to running 40's with a full hydraulic steering system.

[@teraflexsuspensions]

Yes you will. Try some 4:88 or 5:13 gears.

[@jameswilliamjones]

This video was hilarious. "I had to sign you out"

[@rodrigocajas166]

Both of u guys r AWESOME!!!!!!!!!!! Smart, teach a lot and a big load of FUN!!!!!! Keep going guys!!!!!!!!!

[@teraflexsuspensions]

Tire choice and how you drive do make a big difference. However larger tires under a JK do improve how they do offroad and improve the looks.

[@austincade5959]

1:25 the girl jumped so hard, she thought he was going to hit her. kmsl

[@RJ-pw9ij]

I would personally never put chrome wheels on my Jeep. They are difficult to keep looking good and Jeeps are off-road vehicles.

[@lwdn3379]

and it just looks tacky...

[@robertallen6710]

..chrome ain't right on a Jeep..and it ain't natchtral!

[@freighttrain7143]

I understand why you wouldn't do it. I love them on mine. 'They will get scratched!' YEP. So? The chrome looks GOOD. The scratches and war wounds look GOOD.

[@AveCatMW2]

You could put a 31" on the stock tailgate, however, it will wear on your hinges. I know on the JKs you can put a 33" tire on the stock tailgate and not break a sweat, so I think a 31" would probably be okay on an 05 TJ.

[@Kaegis]

I went for some Hankook DynaProMT 295-75-16 which are nearly 34". Pretty good, but next time I will try a 255-85-16. They are 33" tall but 10" wide which are better as they create a longer tyre-print which is what you want as opposed to wider tyre-print. Good Vid.

[@MinegishiMinami8]

where is the location of that sears? looks like a great place for vacation I like the scenery in the back nice tires

[@teraflexsuspensions]

All depends upon what size of lift you have installed.

[@mrfrmguy]

I have a 2004 jeep wrangler x and i'm getting a 4 inch rough country lift for it. which tire do you think would look best with that lift? I was thinking 33's but i'm not to sure.

[@thebarcodestv]

My favorite video from you guys so far... Thanks for sharing the info and to be actually funny too...

[@white5spdef]

In metric tyres the first number is the width, the second number is the sidewall height in percentage of the width. (255/75 r17 ) Width = 255mm or 10.03 inches. Sidewall height is 75 percent of 255mm =191.25mm or 7.53 inches. Now multiply the sidewall height by 2 and add the wheel height, in this case 17 inches and you get 814.3 mm or 32.06 inches. (255/75 r17 = 32.06x10.03x17)

[@zdrambo0]

Awesome video. Info every first time Jeep owner can appreciate

[@MrNosensejack11]

Why did she flinch when he walked up to the 40 lol.

[@heymikes]

Bad info @ 2:00 (or at least a little misleading) The second set of numbers is the height of the side wall, written as a percentage of the width. IE: 255/75R17 75% of 255 is 191.25 so in inches the tire would be 10.03in wide and 32.08 in. tall (7.52(sidewall height) X2 +17(wheel dia.)) So written as a floatation it would be a 32X10R17. Get it?

[@teraflexsuspensions]

Install the tires and lift, then drive it around. You might find that you are happy with how it drives. Now if it's an older 3.8 motor JK, you might want to consider 5:13's.If you have a 3.6, the stock gear might be fine or some 4:88's.

[@teraflexsuspensions]

Wheels with 4.5" backspacing or less, 17x9's. Duratec or Goodyear MTR Kevlars are great tires.

[@-OokySpooky-]

I live in montana with a 2003 Durango daily driver. 33s, no lift, on a 16x10 wheel, perfect daily that still let's me go anywhere in the mountains I need for hunting. I think next month I'm gonna do a simple 2 inch torsion lift and maybe step it up to some 34s or 35 just to make it a bit easier. I dont need to go super insane. Youd be surprised just how effective 33's alone are at taming pretty much anything outside of full blown rock crawling

[@klidraik]

Great video! Just picked up a new JK, looks like 35's for now! Great comedy.

[@reesenewland1355]

[@teraflexsuspensions]

Daniel, it really depends on the area that live in. Do you live where it's really flat or where you have to go over hills/mountain passes?

[@MDCBilge]

The second set of numbers is the sidewall height as a percentage of width, aka the "series," in this case a "75 series tire." You're 255/75R17 then would have a sidewall height of about 191.25mm. The tread width (not to be confused with tire width) will vary slightly from series to series but only slightly and depends greatly on the manufacturer To get the tread width you really need to get that from the dealer or manufacturer. (255*.75)*2*.03937+17= a 32 in tire (see the 255, 75, 17?)

[@teraflexsuspensions]

TeraFlex 6" Long Arm kit, Tera60/Tera44 axles, HEMI 6.4VVT, etc.

[@ed0985587]

Also this video doesn't talk much about wheel size. My question would be what would the pros and cons of 17 vs 18" wheels? Love the look of 18's, bit will it hinder me long term?

[@bobbyratliff3349]

Hate to tell ya but a 255 is a 255 no matter if it's a 60 or 75 it's the same width the second number is the sidewalk height in percentage of the width so a 255/75r17 is 255mm wide and the side wall height is 75% of the width so your over all height is 255x75%=191.25 the times that by 2 191.25x2= 382.5mm of side wall now convert that to inches there is 25.4 mm in a inch so 382.5/25.4=15 inches now add 15 inches of side wall plus the 17" wheel give you a 32" tall tire

[@richardvanvoorhis306]

True. Also, when mentioning the width in inches, she pointed to the edge of the tread, which is wrong. It measures the section width, where the tire balloons out. Makes a lot of people feel ripped off when they measure their 33x12.50 and come up with 10.25 inches of width.

[@gerryharmon1669]

[@teraflexsuspensions]

[@paulquince5470]

Good info..35s look good for mild off road and street.. You have some hugely stunning scenery there btw!

[@gerryvangool7005]

Actual way to convert metric to standard measurements. Example will be 255/75r17 First you convert your section width by dividing by 25.4, because theres 25.4 millimetres in an inch. 255/25.4=10.04inches so the tire is 10.04 inches wide. Now multiply the width by the aspect ratio to find out how tall the sidewalls are 10.04x0.75=7.53inches since there are two side walls top and bottom we have to multiply by 2 7.53x2=15.06inches next add the diameter of the rim 15.06+17=32.06inches so a 255/75r17 tire is 10.04"wide and 32.06"tall.

[@cojeepjk6025]

Very informative series of videos, well done! However, it would really help if you addressed the issue of "actual" tire height. Hold a tape measure and show us really how tall they are. Also what lift would be needed to clear them. (W and W/out stock fenders Please!) TY :)

[@acthilina]

[@dwimmerlaik2251]

Love the video. Great information and its very funny as well. You have really great comic deadpan timing.

[@sproesser1]

Another factor is tire pressure. The smaller your wheel, and bigger your tire, the lower you can get away with. We explore Colorado mountain trails. I run 33's on my 17" wheels. A friend runs 35's on 16" wheels. I am comfortable running at 17psi, he goes down to 12psi. On a rock obstacle, his tire flexes and grabs it significantly better. But he needs to air back up before driving home, or to another trail. I drive no faster than 45mph, and air up the next morning at home. He has a pump(heavy) in his vehicle. At slow speeds, the lower psi really smoothes out the ride too. I would air down just for the better ride alone. Also, If you like to go fast, too big a tire can be bad.

[@dylankrone8845]
