stock hub caps? lol
okay, so far 18x8.5 is alright...as long as the offest is the right size (if it's in the low/mid 30's, it should be alright) ALSO, if the hub pattern on the wheels is anything smaller than (114.3 or 115)x5 it won't work without an adapter, and I wouldn't trust adapters. (some people do, though). if it's bigger than 115, you'll need hubcentric rings. (this way the hub supports the weight of the car, not the lugnuts.)
that tire is a good size for 18's.
