i just installed new tires the kumho ecsta asx 225/45/17 on the stock rims and mounted and balanced them. ever since i put them on my car has been pulling to the right. so i went back and had them rebalanced and check all the tire pressure but still cant solve the problem. the guy at the shop told me that i might need a alignment?? but before with my stock tires i had no problem with my alignment and i have never heard before that i need to get wheel alignments just for changing to new tires. does he kno what hes talking about? any fix
