Thats what I thought? Seems like an odd opinion, especially for a performance car.

You've got grip levels to think about, wet and dry. Wear rates, some tyres last 5000 miles, some last 25000 miles. Sidewall structure, some tyres have significantly firmer sidewalls, which can make the car feel SO much more positive on turns, but make it harsher to drive etc etc etc.

If you think a tyre is a tyre, then do you think a car is a car and that a Yugo Zastava is as good as a Mk2 FRS?
