Trackday tire pressures...

I remember there being a question about tire pressures for Diablo Corsa tires, I was way off. Anyway, I also remembered a Roadracing World article on tires. So I pulled out the story to see what psi's they were running. They tested 8 street/trackday tires. The pressures are the manufacturers recomended settings.


Avon Avaro AV49/50SP Pro 31psi/30psi front/rear
Bridgestone BT014 31/30 psi
Continental Conti Force Max 31/31 psi
Dunlop D208GP 31/31 psi
Maxxis Supermaxx 30/30 psi
Metzler SporTec M1 32/32 psi
Michelin Pilot Power 31/28 psi
Pirelli Diablo Corsa 32/32 psi

So there you have it. I hope this helps somebody out there.

The Pirelli Diablo Corsa runs better at 32 front 34 rear psi. You get more life from the tire and no loss of traction.

I'm pretty sure that the Pirellis are ment to be run at 35psi hot. So they might say to start off at 32 in the front and 30ish in the rear.

I'm not sure about Dunlops
And the Michelin Pilots Power Races are 22.5 psi in the rear and 31ish in the front.
I think when I tested the power roads I ran 28 rear and 31.5 front. (which are awesome tires (for a street tire)I did 1:13.2 at blackhawk)

I'm running 32/34 on my DC's as well. My rear tire heated up to over 40 last Saturday and when I emptied a little air from the rear tire it felt a lot better out there on the track.

Never a bad time to climb... unless the weather is really horrible, and then you climb inside!

I think I might try 32/32 at BHF next month, especially considering my rear shot out from under me when it was at 32/34

should probably check it periodically throughout the day. summer track days can heat them up to something unexpectedly high

Dan you are correct but that is for the Supercorsa race tire. The above pressures are for the Diablo Corsa, which is made different from the race tire. They need more pressure for the sidewall construction.
