Great tires

Great off road tire really bites in. Very quiet and good handling on the street. 2nd set of 35's I've put on my 2015 JKU.

Great on all terrain

Had these and the prior MT's on my jeep wrangler 2013 17" wheels with 35" diameter for past 3 years. They flex well for a radial at around 14 psi or lower and will stay on the rim without bead leaks at 17 psi 100% of the time when wheeling. Only lost one due to sidewall damage but I deserved that when climbing a muddy sharp rocked hill. Regardless I have been pleased with these tires and just ordered 2 more due to tread wear but they are still at 40-45% after 2 years with these 2 tires and daily driving as well. I break the beads a lot but air down to 15psi regularly. I used to wheel 3 times a month but lately only once per month due to new baby. Given the market for tires these are reasonably priced given the value that you get from them..

Great tire

The tires look great, I catch people staring at them, hardly any noise cruising down the road, handle well on pavement, off roading is good as well. No complaints.

Lets's Rock

So far this tire is fantastic. It is not noisy but has a nice "Hum" cruising down the pavement. It is very predictable and does not have any unwanted deflection when hitting imperfections on the pavement. (Also had Rubicon Express Short Arm Lift, so this may also be why this tire is driving so well along with the King Shocks) I went from BF Goodrich Mud Terrain KM-2's 33's to these Pro-Comp 35's. I got 44,000 miles from the BF Goodrich and could have got 50K if I would have rotated the tires a little more. So I am very anxious to see how these wear. I have already received numerous comments on how aggressive this tire looks but not overly aggressive that makes for a good daily drive and a serious weekend warrior. I cant wait to get more Off-Road and a little Rock Crawling in to really see how these react on the trail. So far, I am very impressed with this tire and would recommend to anyone...

this tire is a good performer

I have had these tires on two different trucks, a dodge and a gmc, both 1500 and both 6 inch lift. I notice that the tires are soft rubber for about 5k miles before they harden up. I have never had a flat or blown tire and got great long miles out of all of them. Be warned, you will stare at them when you first get them. It has that atractive good looks.

Looks awesome rides smooth for a mt tire

Aahhh can't talk about other brands so.... Best mud tire out there wears better then most mud tires yet does the job of a mt. Very happy medium. Almost too quiet. I like the roar of a good mt & these are quiet.

Great all round tire

Also replaced Terra Grapplers with these right before a cross country Jeep adventure to UT, NM, AZ, and Colorado. Put 5600+ miles on them in two weeks on road and offroad in Moab, AZ, and Colorado along with the interstate driving between NC and there. No complaints with these tires whatsoever. Rotated/balanced them mid trip and they are still smooth and quiet as day one. Deep sand, rocks (some quite sharp), slick rock, gravel roads at 50+ MPH; no problems at all. Performed flawlessly.

Awesome Choice

These replaced my old set of Terra Grapplers, and I couldn't be more pleased. Anywhere the terra's struggled, the pro comps have more than excelled. They grip incredibly well in mud ranging from sticky to super slick and the tread hasn't clogged up at all. They ride really well on the street and have an awesome growl. I've only ran them for a few thousand miles, so I can't comment on tread wear, but so far they've been worth every penny!

Can this tire be mounted on stock ford duelly rims? I think they are 6.5 inches wide. I already have 2 inch spacers between the rears to handle the bubble. I am running 305-65-17's now with no issues

Asked by Jay from Tampa, FL on

Hello Jay, We suggest against installing this tire on a 6.5" wide wheel. We recommend a 8" to 10" wide wheel with this tire. Thank you.
