i have 18/8's
I have 18/8s, and the local tire seller guy let me try a bunch of old ires on the rims to see what fit best, but i ended up liking 245's best, teh seemed to fit very nicely-and were easier to get on-armed with this info i ordered my fk 451 falkens-245/35/zr18. hope this helps-also, and 8" rim isnt meant to have any wider than a 245-otheres do it neway.
