noise!!!

i just put on some 18" racing hart c2s on my car yesterday. when i drove it around a few miles, i started hearing a knocking noise under my car when i let go of the pedal. im thinkin its my cv boot but im not sure. can bigger rims wear out your cv joints? i mean...i just put them on...then all of a sudden i hear that noise.

if it was your cv, youd feel it knock just as well, sorta like small speed bumps. as far as just upgrading wheel size, it should be causing anything to knock.
