While Firestone might be a decent shop for your tire purchases, do not use them for servicing your vehicle...at least for older cars. An elderly friend took her old car to them to investigate a problem. She's over $400 poorer and the problem is still not fixed after multiple visits and multiple changes in what the solution should be. I'd rely on your car dealer or a trusted mechanic to service your vehicle. Let the tire shops stick to that only.
