Going to Autobahn a week from Friday for some "spirited" driving and noticed my two front tires are really lean. Trying to buy two new Goodyears from Tire Rack (amongst others) to no avail. They do have 2 Bridgestone Potenza's in same size at $236/tire, but I'm wondering, should I replace all 4? Back tread is still more than ample, and apparently, Goodyear's are nowhere to be found. Car has just under 5 M miles total, rear tread looks great, fronts nearly slicks. Do I replace only two or go with a whole set of Potenzas?
Any input greatly appreciated.
