I'm not sure how thick my tires are, Is it on the tire somewhere? They're 28" Uniroyal liberator A/T's, I've been on some rough stuff before, but not for that long probably.

Are they 225/75-15's?

Are they LT? They should have a letter to designate the load rating. Mine are E's such as equal to 10 ply. D = 8, C = 6, B = 4
