Tamiya B3
 

How long do the Tamiya B3's last normally at peak performance? I've seen TCS racers replace the B3's every race to stay competitive in GT2 and GT1, but that's awfully expensive, as they are 45 bucks for each set.

2 run at most if u wanna stay competitive.

A complete tyre, rim and insert package (set of four) is pretty expensive here in South Africa so we run them till you see the reinforcing band or they split. Sure you will see a drop in performance but if you are a reasonably good driver then you can still be competitive :D
