5.0 Great all around tire

Good on the trail at low psi. I've driven snow, mud, sand and wet pavement, no big rock stuff. Always kept me going. Strong side wall. Had a nail in one that leaked about 1 psi/week. kept on rolling. 60k plus miles over 10k on the trail. I bought them again.

5.0 Pro Comp rocks !!!

5.0 Love these.

Bought these for my 2018 Wrangler JKU. I bought a lift too, but didn’t need it. That will go on in the spring time. So far I love them, and we’ll see how they brave the Wisconsin winter. Shipping was so fast, literally shipped the same day I ordered the wheel and tire. Kudos to you 4WP!

5.0 worth it!

I have used pro comp many times and they last and can take the rough roads and conditions. I went with sport tires this time because I do need such a aggressive tread for this truck.

5.0 Nice tread design, quiet on the highway

These all-terrain tires have a very aggressive looking tread pattern, which I like. They are very quiet on the highway also considering I am running a larger tire (33x12.50R17). I hope that I get the expected mileage figures for these tires, (over 30k at least) which will make the investment very positive.

4.0 Pro Comp AT

I bought these tires for a 2007 Jeep Wrangle JK Unlimited Sahara that my daughter is currently driving. I only gave them four stars due to the fact they are just a little stiff as they are a "D" rated tire. I would rather of had a "C" rated tire for a smoother ride. But so far she says the ride isn't that bad and is pretty happy with them and on road traction is very good. We haven't had a chance to take them off road yet either as most of the trails here in Northern Colorado haven't opened up yet.

Q: How much air pressure recommend for these tires?? Answer this question

A: mine where 10 ply tires , on a 2500 HD i ran 50psi when not hauling loads and 65psi when i was , high psi when not hauling heavy loads makes for a rougher ride on rough roads so the lower psi makes for a easer ride.

Answered by clark22 from MD/WVA Mountains on 12/23/2021

A: Too many variables for a single pressure recommendation, If this is an OE fitment, they’ll need to refer to their owner’s manual. If larger than OE, it will take some trial an error. A safe place to start is around 10% under max psi. Max psi on this tire is 65 PSI so start around 58 and test from there.
