I like Hankook RH06s. I am about to order a new set

 

I know Avalanches are shaped a little different but, I have Continental 285/50/20's and drive **** out of it. 3"ish drop in front. I never measured but I'm on the shortest shock QA1 makes and on Atomics mounts. Tires were cheap and stick great.

 

Cooper wouldnt be bad tire either, of they have a sport tire.... Have seen good results with theire rs3a's on camaros (not a truck, but)
