I'm talking about running race tires...the BT003 pros are a race tire and not just a street tire. I agree totally that switching to race tires is the right thing for me. I still don't think buying the latest and greatest is necessary. I've improved greatly in the 2 years I've been to a track, but the few tenths of a second I might get from running an R10 (or any other manufacturers newest tire) over a BT003 still isn't going to put me anywhere near the podium. Of course I know and plan on getting better, but the reality is I'm just not there yet. But this is what redkow is getting at...if a rider is running 1:35-1:30 lap times at nelson, race tires are not going to make him faster. He's not even pushing the limits of the tire. He's not going slow because of the tires, he's just going slow. Put him on race tires and he's still gonna run a 1:35.
