| My preferred tyre on st4s was bt010 for a combination of grip, wet and dry and reasonable wear rate (4000 miles from a rear 6000 miles from front)
Bridgestone bt020 on the rear would last a lot longer as someone else has mentioned.
Currently very impressed with standard compund Pirelli Diablo's. Current set on 996 have covered 2500 miles, performed great with not much wear, so i've joined the hordes who rave over them |
