## Description

Tires to dominate off road.

Review: Amazing. - Quiet and rugged. I was super leiry of buying tires on line. These tires are amazing. Very little if any road noise. Went from 265 to 315. Felt very little loss of power. The difference on the trails were significant. These tires bite and release the mud better than I could have imagined. Absolutely love the look, agility, and off road capabilities. Would highly recommend. I have tried uploading a picture but it won't let me. Anywho. They are amazing
Review: Great price for 37's - I've been running the Cooper Discoverer Pro STT's for a while now and needed to replace 2 of my tires. desertcart had the best price on 37x12.50R17's I could find, plus I didn't have to pay a bunch for shipping. These tires are great! Not a ton of road noise and they hold up great while off roading.

### ⭐⭐⭐⭐⭐ Mean look for any off-road vehicle
*by J***N on May 29, 2025*

These are the best tires I have ever had. I’m on set number 3. They get beat up when I go wheeling but they have good grip and get the job done. I hate that prices have gone up, but they were worth it to me. I mounted them to my beadlocks myself in the garage and have not had to rebalance the wheels.
