How much clearance between UCA straight and full lock? I put a Toyo MT 37x13.50 18 on mine, but it didn't have much clearance with UCA.
I have been running the 295 RT Trails on my 1500 for 13k miles and they hardly look used. I have them on my boys 2500HD and they aren't holding up at all. Not sure if it is bad tires or just not suitable for that weight.
