Great tire. I drove it in snow and ice when i bought them, then had the center lugs siped, huge difference and unstoppable. I aired to +/- 26 psi and got over 45,ooo mi out of them, still sold them for $400. A friend over aired his in our jeep club and didn't get half the life from uneven tread wear. Bigger tire with the same weight needs less air. I painted across the tread and drove a block, adjusted pressure, retest until full road contact. Now that there is less tread, they are noisy like the rest, but bearable still with a soft top. Now that the siping is gone from the center lugs, they are lacking. I'd say center lug siping is a must with large block tires. These never chuncked from siping. I would buy them again but they don't go as big as i need unfortunately. I'm off to try the km/2's in 35's!
