Save Money By Thinking Ahead One of my friends, Dan, who owns another auto shop, asked me to remind people that any all-wheel-drive vehicle must have tires replaced as sets of four, rather than in pairs. The rolling diameter needs to be the same on every tire for AWD cars, and if the diameter is different, there is the risk of ruining the transmission and differential unit. He had a customer who replaced only two tires and as a result had to pay for more than $3,000 worth of repairs. Front and rear tires usually wear at different rates, so by rotating them every 5,000 to 10,000 miles, all of your tires will wear out at the same time. This will make replacing all four tires less frequent and save you money. -George Rode
