Where do I find motorcycle tires rated for over 200 mph?
Been searching but can't seem to find anything.
Thanks
-
Bridgestone Battlax R003, there could be others, have to say racing on the tire. I hope some motorcycle racers chime in here.
-
That's one of the correct answers...
If it says racing only it is allowed....
-
Here is the list I was recently given by Scott Mattern of SCTA when I asked about acceptable tires over 200mph-
Michelin: power cup EVO (DOT), power slick EVO (slick)
Bridgestone: R10 (DOT), R11 (DOT), V01 (slick), V02 (slick)
Dunlop: GP-A (DOT), KR (slick)
Pirelli: Diablo Superbike (slick), Diablo Supercorsa SC (DOT)

BMST dont have the same requirement as SCTA, Tire choice is more the riders , but the SCTA acceptable tires are good options
The 003 is out of production and be hard to find , the R10 replaces it but is a little softer
The GPA chunks fairly easy if you wheelspin much and i would not use them over 230mph , had a front delaminate
Are you still thinking Sporty ?

Has anyone heard of the Dunlop Q3 or Q4 tires? theyre DOT approved track tires/ track inspired tires. I had hoped to use the Q3 or Q4 for my rubber of choice this summer. First time going down, im having some anxiety about driving 1000 miles just to fail tech so im glad i found this forum!
-
I did a bit of research on these tires. The Q3 has been discontinued and replaced by the Q4. It is advertised as a "Track Day" tire which means soft. Soft tires do not do well in LSR due to chunking when they heat up. I would keep looking for a harder rubber in the W speed rating.

Thanks Don! I will keep that in mind.
I had a thought, that maybe because they were DOT approved and dual compound, that perhaps the patch of rubber in contact with the salt would be harder then a standard track day slick. Any thoughts on this?
Has anyone you know ever ran the Q3's or 4's?
-
The Bridgestone Sport Touring T31's are "W" rated. They have a harder compound than race tires
-
From looking at the photos of Al Lambs 282 MPH Honda, he has Dunlop Sportmax tires on his bike. I could not make out the exact model of tire though. It looks like it may be a GPA-Pro model.

Fairly sure they are the Indy version, his video looks like mine with black flecks spoiling the view
he had tire contact with the water tank though , mine were not Indy and had no excuse
The 300mph tires were Dunlop KR slicks , they were also outside there comfort level and chunked every pass , but both riders had no deflation problem
-
How much did Al Lambs tyre grow at those speeds Greg ?
-
More than they expected ;)
Dont know the actual numbers Ronnie, but they were beating the hell out of the water tank for clearance , and it still contacted , i would be guessing and say 1/2 to 3/4 inch
actual at speed clearance was hard to gauge due to the unknowns of fork position and suspension or frame flex
