I've the lot done really wheel alignment, balanced. Yes I have aftermarket 15" wheels brand new tyres. One interesting I've found out this weekend while I have my car off the ground was the tyre is not perfectly round. When I spin them you can just tell that its not really round like minor bump, are they suppose to be perfectly round?
