If you hear squealing from your regular or tuner tires, you could be dealing with under-inflated tires. You may also have tires that are at the end of their life. If so, it's time to get some new ones. Your tire service should include new tires, wheel balance and, after a recommended number of miles, tire rotation. Many drivers often overlook tire maintenance, so chances are you could be hearing the squealing earlier than necessary. Avoid the squeal with regular tire maintenance-the rotation, good wheel balance, and properly inflated tires.
