hey i was looking on the internet today and saw that irok makes a 39.5/13.5/17 radail tire. I heard that the tires look very very skinny, will those radail tires both out last a trxus sts and tsl in the same size. Worth the extra couple hundred on the tires. Also how the iroc do millage ect. Its 90 percent dd and 10 percent fooling around. Need millage.

My buddy has some 39.5" radials on his cobra 5.0 powered FJ40, they ride ok, should last half decent and do ok offroad. Personally I think they are pretty much the perfect width for a 40".
Ive always heard there just a notch below boggers offroad
