Title: Tires (probably for the fifty thousandth time......)
Post by: Schmergen on March 31, 2015, 04:35:46 AM

I'm sure you're all sick of people asking the question (and yes - I have tried the search function) :dhorse:

I've had some conflicting advice on the subject of tyres (tires for y'all in the States)

I'm gonna be running in a class with a 200mph plus record (on a modified ZX12R). According to tech inspectors Z rated road rubber is out of the question. However, I spoke to a competitor recently (who is SCTA'd to 250) and he is using part worn race/road legal tyres that are still Z rated.

What I'm really after is someone just to let me know a make and model I can go for............

I'll set the ball rolling:

How about part worn Pirelli Diablo Corsa SC2's?

Who said Z rated tires are out of the question? They have been used by riders throughout the history of BMST. I think the most used tire is the Bridgestone Bt003 which is a ZR rated tire. That is the one I have used for years.
BTW, the rulebook does not specify the type of tire. Instead it is up to you to decide which one is best for your class.

Road racing tires are not good unless they have a "Hard" compound. Most drag and road racers use a soft compound because it is on asphalt. You will just shred your tire on the salt if it is a soft compound. I know that from experience.

SCTA has different rules regarding tires for 200+ mph bikes than AMA does.  If racing at BMST a ZR rated tire is legal as long as it is on good shape.

Battlax R10  they are marked racing and dot stamped and can be got cheap from ebay for a scrubbed set.  OK for Speedweek
