Looks like I'll be sticking with 305/35/18's, as my rear rims are 18x10's. I'm not sure how much life I actually have left on my nitto drag radials, there down to the wear bars. Not to happy how long these have lasted, roughly 4k miles so far and zero burnouts or track use. Tread depot has them for 321 each, and tiresdirect is 317.98. Anyone know other places to check?
