On the track do you typically run more or less tire pressure.

I have run more, but recently was told to run less pressure.

What is the take from the experienced riders on this?

BTW this is on Dunlop 208 GPA's. I know the Pirellil's usually take more air.

I normally run 28 rear 30 front.

I'm no expert, by all means, but my take is that you run less PSI at the track for a few reasons. One is that the tires warm up greatly (and much quicker) on the track due to the aggressive riding on them, which increases the tire pressure. Another is that it allows more of the tire to sit (grip) on the track.

BTW, I've only run 208 GPs on the track and I run the same pressure you do. (28 rear, 30 front). For street riding I up the pressure by 2-3PSI on both.

But what about if it is colder that pressure is for when it is above 80 on the track.

Do you change it for when it is colder?

The question I meant to type was:

Do you change tire pressure up or down if it is colder out, and how much normallyy in relation to the temp change?

well im not sure about this myself, but i think confort and gas milage also comes to play here. i would max it on tire pressure if it was me, so i get better milage, less drag on the bike. as fas a confort i would get a corbin seat so i dont feel the hard ride.
as fas a cold air i think it depends on rider, if tire pressure is maxed i would take it easy the first 2 laps and then gun it. When the manufaxturer tells you the max air pressure they already take into consideration in their design of the tire for expansion and contraction.

If you remember that OEM tyre pressure specs. must cover a blast down the Autobahn with your West Virginian Anorexic girl/boyfriend and luggage thrown over the back on a 100+ degree day, and are set more by liability lawyers than engineers, then figuring out which direction to go becomes pretty obvious

What Nick said.

Adrian, we've beaten this topic to death, if you'd like to dig-up the old posts. I know you're just trying to stimulate discussion, or I'd go on about it more. To give it a bottom line though, measure tire pressures when they're cold, and run lower psi for the track. The reason is obvious...

You want your tires to last longer on the street.
You want your tires to provide more grip at the track.

It's that simple.

Put the bike in first gear and rip open the throttle and dump the clutch. Make sure you are directly behind Carnage when you do it.

so some put more...because when the tire expands the level of tire pressure will lower and level.
