System 3 Offroad XTR370 Honest tire review with twisted ending

We give you a straight up review of what I think of the tires and most importantly if I will buy them again. System 3 offroad hit a homerun with the XTR 370. It is an amazing tire for most all terrains that a SxS will ever come in contact with. This tire will be great on most UTV's and SxS's including Polaris RZR, Honda Talon, Canam XR3, and the Wildcat XX to name a few. Tires are a great UTV accessory to add.

Let me know what your favorite tire to run is. Is it something common or something totally different? Thanks for watching.

[@jjadventures6655]

Roxxzilla for the win.

[@GrimRZR]

That seems to be the trend.

[@russwalker9875]

I really like the original bighorn tires for all around riding, but just fitted my rzr with my first set of 370’s today. I hope I like them just as much, I almost went with the carnivores but they don’t wear as well do to being super soft and are great for rocks.

[@GrimRZR]

@@russwalker9875 you are going to love the 370s

[@markball7028]

@@jjadventures6655 roxxzillas are a great tire. But they have weaknesses. Number one is mud, and number 2 snow. They don’t self clean very well. They are the best tire out there far as I’m concerned for rock crawling. I don’t consider them a great all terrain though.

[@jjadventures6655]

You talked so good about them the whole time and then at the end. Nice review.

[@GrimRZR]

Thank you. I hoped it would intrigue people to watch to the end.

[@AdrenalineJunkieProd]

Thanks for the review! Helped me make sure I made the right choice ordering these.

[@GrimRZR]

Can't wait to see them in action on your videos

[@chadhall5921]

370 is a great all around tire and so is the xt300 I’ve been running them for a couple months now pretty impressed

[@GrimRZR]

Haven't ran those yet. They look really good though

[@holbertjosh]

Put a set of these on my talon x4. Got to try them at rush offroad last weekend, definitely love these tires! I highly recommend them.

[@GrimRZR]

They are a great tire. I'd like to see some 33's in person. The tread is supposed to be taller

[@SweetPeachlifeslot]

Congratulation 👍 over thousand sub awesome 😘😘😘

[@GrimRZR]

Thank you

[@CrashCitySxS]

We just put 35” sticky roxxzillas on the wife’s buggy. The work!!! Got her right through the lions den at black mountain. Good video!

[@GrimRZR]

35's makes a big difference for sure. I want to run them but im not sure if I want to go portals or gear reduction.

[@CrashCitySxS]

We were interested in portals but came to the conclusion that for us the negatives outweigh the positives with them. Too many other things to upgrade your ride to handle them and probably our biggest negative is we feel they will take away from the challenges of not having them. It’s a toss up really. I see more need for the gear reduction aspect than the extra clearance. But the 35” tire size is a game changer for sure.

[@GrimRZR]

I was curious how axles hold up with 35's without portals

[@CrashCitySxS]

Good question. We’re still on stock axles. AA stage 3 tune AA clutch kit with high load helix been on 32’s and now 35 so we’ll see how they hold up

[@GrimRZR]

Keep me posted. I've recently upgraded axles but still everyone needs to know. Thanks

[@xXGOTCRABSXx537]

I love my 370’s !

[@GrimRZR]

Yes sir. What are some of the other tires you have run?

[@xXGOTCRABSXx537]

Grim RZR dirt commanders and the maxxis bighorns. I didn’t care for the big horns, very weak. Great review by the way!

[@GrimRZR]

Thanks. Haven't got to ride with any dirt commanders yet.

[@xXGOTCRABSXx537]

Grim RZR they were honestly a really good all around tire. I never had any holes/flats with them. Pretty affordable too for an 8 ply.

[@GrimRZR]

Whats your next tire going to be? Im up for being different.

[@markawesome439]

Rockzilla the name just sounds good

[@GrimRZR]

And it's spelled cool. Roxxzilla. They have a stickier compound. I haven't ran any yet.

[@GrimRZR]

Ive been seeing some of the new sizes and the lugs look really big. Maybe I should get a set of the 33's and give them a try.

[@AdrenalineJunkieProd]

I just ordered a set of 33x10x15 cant wait to try them! Thanks for the review.

[@natejones129]

Have you used these tires in snow? Been wanting tires good for everything but really good for snow too

[@GrimRZR]

I wish. Not that much snow down here.

[@dennywright3132]

what size did you have? I'm gonna buy the 35 x 10 x 15 with the 1.25 lug. I have a Honda talon and will soon be installing a 25 % gear reduction with a full exhaust and a tune so I don't think the weight should bother it.

[@GrimRZR]

I had 32's.

[@daniels8701]

Did you have to do any clutching or gearing to your Rzr to run those tires? I’ve got a Rzr 4 Xp 1000 on 32’s and it keeps getting the belt hot when I’m crawling around in the rocks.

[@GrimRZR]

I didn't then. Actually ran 35's for a while on stock clutch and gears and belt. You just have to drive it like a stick shift in rocks. Once the belt engages you need to keep that momentum. Stopping, starting and trying to be easy in rocks will heat up a belt with any kit or gearing

[@GrimRZR]

I just finished a gear reduction and it is amazing. Highly suggest for anyone that is not just racing or duning

[@hawkfan72]

I somewhat cheap test would recomend Hunterworks thick belt it has worked great for me in the Washington state mountains

[@upsman1313]

How would you compare them to the Carnivorous? On price and weight, the Maxxis win. Gonna be on trails and lake bed mostly. I have BKT for deep mud rides, but want these to do their job. Thanks for any info.

[@GrimRZR]

I never ran carnivores. Everyone around me that ran them always complained about sidewall holes so I never tried them. 370's are still a good tire but I'm liking Roxxzillas and MRT the most right now

[@donnywarren4249]

Trying to decide if I should go to a 33" 370 on my Talon X4 LV. Anyone you know running them on a Talon? I have the clearance with the Super ATV front A arms and wheel spacers. Currently running BFG KM3's, and they're just OK, i've never been 100% happy with the appearance or grip in muddy situations.

[@GrimRZR]

They are awesome. Haven't rode much with any talons. If you ride in muddy conditions much these will be much better than km3

[@HaRtAnDsOuL99]

I want these so bad but I got carnivores right now and it’s almost wore out and still pulling good. I’ve seen someone with sticky roxxzillas try to climb 24 at indian and had to beat it in 4x4 to get up that I’ve went right up with me in 2wd with wore out carnivores

[@GrimRZR]

I think most folks agree that Carnivores get great traction. They just seem to get more sidewall punctures than anything else.

[@nathonquinton9397]

Thanks for the review. What other tires have you run this far?

[@GrimRZR]

I've ran the Bighorns, Coyotes, Tensor DS, then these. Some of my friends I ride with have run Carnivores, Roxxzillas, K9's, KM3s, and Warriors.

[@GrimRZR]

Whats your favorite tire?

[@nathonquinton9397]

Right on. I’ve only had roctanes and I’m not a huge fan. Guys I ride with have biggorns, terrabites, and carnivores. I’m for sure gonna try out the system 3 this year

[@GrimRZR]

Do you ride with anyone that runs Roxxzillas? Unless you ride a lot of pavement they work good. From what I've seen anyways.

[@nathonquinton9397]

Thanks for the info. Never seen them in person tho but it’s worth checking out!

[@whiskeymayne3678]

You said your gonna get some rockzillas next, understandable. Have you considered the K9 Supergrips? Im in a toss up between the two, not only rock crawling but my local park is tons of rock

[@GrimRZR]

The K9 might be good if you ride a lot of pavement and are concerned with how long they last. Everyone I ride with that bought K9's were not happy and sold them. It's not that they aren't a good tire just a noticeable difference when compared to these XTR370's or Roxxzillas.

[@whiskeymayne3678]

@@GrimRZR awesome man thanks for the honest feedback. how would you rate rockzillas on normal trails?

[@GrimRZR]

@@whiskeymayne3678 I can only go on what I see since I haven't tried them yet however they only real downfall I can see from Roxxzillas are they don't perform great in nasty mud and they are a little harder to steer due to the flat tread profile

[@whiskeymayne3678]

@@GrimRZR fair enough thanks man. i dont know anyone with them personally so thought id ask

[@GrimRZR]

Lots of things to consider with tires but I just try to be honest about them. This is just what I've seen in person on the trails we ride. You can imagine any tire that really does well off road will probably not last as long. For some people that's a big factor but it's not as important to me .

[@ShadowArsenal]

Do you have stock trans gearing? If not, how does the belt like the added weight?

[@GrimRZR]

I did at that time but now I have done a gear reduction. Definitely suggest it

[@ShadowArsenal]

@@GrimRZR Thanks. I think that's probably the way to go too. Hard climbs with my Carnivores heats my belt up, can't imagine these.

[@GrimRZR]

@@ShadowArsenal I've went up to 35's and long travel since this video but I love it.

[@nate.hanlon]

heard the super grippers was like roxxzillas but better for other stuff that’s not just straight rock

[@GrimRZR]

I haven't seen them good in many cases yet

[@michelleroetter6515]

Like to know how they stack up in the snow.

[@GrimRZR]

We very rarely get any snow.

[@trevinguthrie9295]

What do you think of these tires in comparison to what you have seen out of k9s ?

[@GrimRZR]

From what I've seen K9's would be one of my last choice unless I was on a lot of roads.

[@trevinguthrie9295]

I was kinda thinking that I just ordered a set of k9s but I’m going to call and get them changed to a set of 370s

[@GrimRZR]

@@trevinguthrie9295 it really depends on what you want out of the tires. If you want more traction off road I would try to switch. If you are looking for a decent tire that will probably last longer the K9's might be okay. I don't get to ride enough to worry too much with how long they will last

[@trevinguthrie9295]

Yeah I ride very little even on gravel mainly all off-road

[@GrimRZR]

@@trevinguthrie9295 I'm not sure if the K9's will do it but when I ran coyotes they picked up gravel all the time. The tread was perfect for grabbing rocks and throwing them in the cab if I ever hit gravel roads.

[@cobyburrow9339]

If you had to choose between 370s or Carnivores how would you ride?

[@GrimRZR]

Never ran carnivores but several of my friends that run 370's have. They say the Carnivores are nowhere near as good as a 370.

[@widetrackb6604]

What is your reason for not buying another set?

[@GrimRZR]

These were awesome but hard to know what you like best without trying multiple different ones

[@timcassone2368]

Have u ran them in the snow?

[@GrimRZR]

No. We don't get much down here

[@BamaTrailRiders1]

roxxzillas for the win lol

I really thought more people would have said something about it. LOL

[@mlaxton1]

Me too honestly😂 Still liking the tires? Ive been shopping for over a month now and can't decide between these or the k9s in a 32

[@GrimRZR]

They are great. The only reason I would even consider getting K9's is if you rode a bunch of pavement. Im sure they work better than some tires but all of the people that bought some when they came out that I ride with have sold them and went to either the Roxxzilas or XTR370

[@Trailnecks]

How do they handle on high speeds? How fast are they wearing out?

[@GrimRZR]

I don't really run too much high speed stuff. So far up to 50 it drives like a car. Very smooth.

[@GrimRZR]

As for wearing out. It seems better than a carnivore. I've got a couple hundred miles so far and the edges are just worn. Height is still there

[@Trailnecks]

@@GrimRZR Thanks for the info!

Well that's good to know that you haven't tried the rockzillas, I'd like to know who's compared the two. The heavy tire concerns me. I was really looking forward to trying it out. Even considering the ProComp XG 35 which is around 13 lbs lighter if I recall. Just on back order :-( ...
