Tyre Pressures For Trackdays ????

[Turtle]

So what are the opinions of some of you guys ????? What pressures do you use on the track........it seems everyone knows something different ?? I'm talking road tyres mainly, and feel free to post up pressures for Slicks as well. Also put down ya tyre size (190/55)


Feedback from others is important i reckon.

TURTLE.........

alot of it actually depends on the day for me mate, if it's a hot day, i put abit more air in, and a little less for cold days, i think alot of it depends on the feel your getting from them, and the feel ya wanna get from them
my opinions anyway

[MATTK6]

oh yeah, i run the bridgy slicks, 120/55 and 190/55
generaly start off with about 28psi

I was on the FZR (with smiley face?)- unsure of tyre sizes, but I ran 30 front and back- checked tyres a bit during day- mostly up by 4 straight after a session (my son john and I shared bike- C and D). Seemed to work for us.

I thought you'd put a bit less in on a Hot Day ?? Due to the extra expansion from the heat ??

As theory goes Mattk6 is spot on, more psi on a hotter day whereas less psi in your tyre gets the tyre hot from a bigger contact patch plus it then moving around, add psi and you have the correct sized contact patch = less heat inside the tyre.

The CircuitBreakers school had a visit from Craig White... who posted here in the Tyres for Sale, his teachings were very simply (see my race school write up)
If its a race tyre then it has a harder carcass, so you run lower pressures, if its a road tyre it has a soft carcass and you need higher pressures or you'll collapse the sidewall.

Details in the sticky schools report.

yeah, it's a pretty simple formula, hot day low pressure= more tyre movement
higher tyre pressure= less movement, and when pushing i want like my tyres to have as little movement as possible

Ahhh...that makes sense ..........what pressures on the track for road tyres ?????

[MATTK6]

even on the road and track for road tyres, i use to run 28-20psi front and rear, and it worked well for me on the powers, but i think there will be other people on here that run different pressures, due to make of tyre, what compound, size, and what they like to feel from them
