I'm getting two new tires for my Mustang. The two back tires are the ones that need to be replaced. My dad and grandpa are insisting that I have the tire shop put the two new tires on the front, and move my two good tires from the front to back. However, the tire shop disagrees since my car is rear wheel drive. The shop says I need to put the two new tires on the back. They even gave me a guide explaining why good back tires are important. Also, several of the tire manufacturers urge you to put your new tires on the back also. http://www.goodyeartires.com/faqs/Technical.html My tires are still on back-order. Any thoughts?
