Tire Pressure

[Jingers]

I am sure this has been covered before, but its not in citr, and its most likely pruned in crsx.

What do you guys use for tire pressure?

Maybe list it in the order of

car ::
suspension mods ::
tire size ::
tire brand ::
tire pressure F/R ::

Thanks, im basically trying to figure out if semis require slightly more pressure or less.

car :: DC2 Integra
suspension mods :: Cusco Zero2, 12k front 8k rear
tire size :: 205/45R16 Toyo T1R
tire pressure F/R :: 35/35 cold

semis require less pressure as a rule of thumb

low profiles (eg < 45 series) require more pressure as a rule of thumb

^^^pls correct me if i am wrong...

need to list what tyre too aye tink? semi or street?

Renault Ultimate Clio
Stock suspension

Advan A048
pressures 40psi hot all around

Feck. How heavy is an ITR?

I would run 048R @ 28psi hot on the Elise.

BTW, borrow a pyrometer or irfrared thermometer and check the temps across the tyre as soon as you leave the track.

If the tyres are hotter in the centre then your pressures are too high.

hmmm would be useful to include damper settings too to those who have coilovers

any 17" semi slick users here ?

[dc2rrrr]

What about nitrogen? I used it last track day, kept pressures more regular but a bastard if you need to top them up a bit. Im going back to good old aussie air for this track day (tomorrow YAY)

[tinkerbell]

i have never used N

but i am looking forwards to tomorrow, i hope the rain doesnt green the track out too much
