Just like the title says. I have BFG A/T's with about 30-40% tread left. They are sliding all over the place when the roads are wet. It kinda sucks because they were $300 a piece and have a decent amount of tread left. They have about 33000 miles on them. I'll ask discount tire when it comes time to rotate but that will be a while an I was curious.

 

yeah you can do it just try to follow the same lines that they had from the start and dont go too crazy.

and if you have never done it then id take them somewhere and have a professional do it. I have never siped a tire but i have regrooved a set before but those where for offroad use only so its alittle different.
