Question What tire pressure Bridgestone BT002 for track?

I am running the Bridgestone Battlax Bt002 Street/Track Day version tires on my 2007 R6 for track days. The pressure I've been running them at is 28psi front and 26.5 rear cold. I would like to find out what Psi should they be at when hot for optimal performance?

I used the BT002 Pro versions my last track day (Hard rear, Med front) and I rode 30 Front and 28 Rear. (Both HOT pressures)

Those were the pressure I got from a guy at a local shop that races WSMC and WERA with them.

I ran the Bt002 RS which is the street/track tire.

I had good sucess with 30 front 29 rear (cold pressure) at the track.

Blue because it is faster.

Thanks everyone. I asked the tire guys at the track and I ended up running 28psi front and 26.5 rear cold pressure and it worked out great.

Re: What tire pressure Bridgestone BT002 for track?

So I went to the track over the weekend and the guys at Bridgestone were there. They said to start out at 28psi front and 26psi rear cold and my target temp was 31-32 hot for both.

Re: What tire pressure Bridgestone BT002 for track?

It's a tough one with those tires. I started at 28/28 cold and the front was perfect but the rear cooked. It ran up to 35 to 36 hot. I added a pound of air to cool it down and it did not make a difference. I ran the next day 28/29 Which is technically backwards for tire pressures. The rear still cooked up to 36 while the front was still at the perfect temp of about 34. I was running about mid pack in the A group so I may have been running a little faster than the tire were really designed for. They had good grip for a couple of laps and then they would fall off very quickly getting worse each lap. By the end of the second day I had to quit early as they would not provide any grip. The sad thing was that the tires still looked as if they had plenty of tread left to run. They were shot from being cooked. These tires are perfect for a solid B group rider that is running a good pace. If you are an A group rider that is pushing in the middle to upper 2/3 of the pack in lap times they will just not be able to handle the stress. They need a lot of cold tire pressure to get the tire in the operating range but wil not provide enough grip unless you run the lower pressures. I still love the bridgestone bt002's as a street tire. they are to me superior to the the 2ct's which would not handle the faster lap times very well.

I use them in the B group and work just fine.
