Not as far as I know of on passenger class vehicles. On bigger trucks that require a CDL to operate retreads on a steer axle is illegal in some states, but not all.Not sure, but isnt it illegal to run re-treads on the steer axle(front) in alot of states. I'm pretty sure it is in Wisconsin anyway.
my tread is almost gone and i bought them in march! i've rotated them and they are always at the right pressure. they worked good but i have hardly any tread on the back tires(on front first). i've put about 6,000-7,000 miles on them. mostly road as it was pretty dry this summer but i would think they should last at least 20,000 even working them. and no i didn't do any burnouts with them.
Hey same here on the all-terrains, At 4,000 miles they are showing many signs of wear, In fact I even went down to discount tire today to talk with a salesman. I am kinda concerned, they were $1000!!!!.
