My left front tire failed and needs to be replaced. I had Bridgestone Potenca G009 all around. They are no longer available. I plan to go on the track in two weeks. The right tire has about 50% thread left.
Do I? 1. Replace the one tire with a current equivalent Bridgestone tire? So one new tire and one used tire on the front axle. 2. Replace both front tires with a current equivalent Bridgestone tire? 3. Other?
I'd put two new tires on at least, and put the older tires on the front of the car... You'll get less tread squirm from a tire that does not have full tread.
