Track Tyre Pressures.

[Yorick]

Got Dunlop Sportsmart TT and just getting ready for the weekend.

The website says

F 27 - 31.
R 21 -26.

Just wondering which limit I should aim for. Which is the hot or cold parameter?

Gonna be 30c on Saturday so want to get it right.

Never had a range to work in before

I don't run them anything like that after recommended by a TD hire guy I trust.
34F 23R both hot, same tyres as yours

I'm suprised that you're asking this with your level of experience, but FWIW, I've been using TTs on my bikes on track (that includes the H2 as well as ZX6 etc) for years so my five bob's worth, FWIW is to stay pretty much with with Dunlop recs- It's what I did on 120 front and 180 ,190 and 200 rears ran at ~ 26R/32F hot, which in the UK equated to cold pressures of 22R/28F , and got great grip and minimal wear with that , even on the H2.

Having said that, the tyre pics you posted in your other thread when you went to this track looked as though they were happy, so whatever you were running with then, stick with that- that's what I would be doing...


(Not of course that you will see this, or even if you do, acknowledge that you have, but I am guessing that I'm one of very few on here that have much track experience with TTs and don't do this silly ignore thing so I'll post it anyway )

Edited to add link to the Dunlop website which clearly states which are their hot and cold recommended pressure ranges

I’ll tell it like it is, it’s because he has no clue whatsoever, useless on a bike let alone anything relating to set up or tinkering. Sadly we have to endure its pish.

Tbf...I think he's pretty decent on track and those moon landings look interesting.
