I own a 2001 ZTS with only 157,000. miles. I am the original owner of this auton the rear tires. This is no BS> I have replaced the tires on this unit 8 times due to CUPPING issues on the rear hydes. I've put multiple brand tires on her and it makes no difference. I replaced rear shocks times, rear bushings, had it checked for alighenment several times. I love this old beater, problem being I would like to buy a new one but cannot go through this again. All tire manufactures say they garrentee the saftey performance, not the NOISE! I CAN"T HEAR THE RADIO LESS A TELEPHONE CONVERSATION! Please any advice would be greatly appreciated! Thanks in advance.
