I have 44" TSL's on my rig (44/18.5x15). Approx. 50% tread give-or-take, grooved.... I'm happy with 'em - they seem to be a good, all-around tire. Can't really say that I've had any issues with 'em. However, I have different desires for the rig - like, I want H1 rims. Since that'll require 16.5 tires anyway, I have an itch to get some 42/14x16.5 Iroks. So I'm at a crossroads - do I stick with what I have, or upgrade to a package that'll have more benefits....? Thoughts?
