I put tires on my Cuda last year. The set that was on there I installed in '97. They looked perfectly fine...no cracks and plenty of tread.....figured it was time. My DDs got tires as well..both are 10 yrs old but had hit the wear bars at about 50k miles. My other toy is a '18 Mustang GT with Z rated stuff on it. The car has 20K on it now and the tires are about done. It'll get new shoes next spring.
