Tyre Pressures
 
Hi Guys, just getting my head round the idea of running without warmers, and how quickly the dunlops will warm up. But, what pressure do you start off with cold, f31 r 28??

Keep calm and carry on!

28 front and rear.

There's no time for warming them up. Flat out as soon as the red lights go out.

:D

If you're hard on your tyres, you might want a little less pressure but you won't be a million miles off with those numbers.

The tyres do warm up quickly, quite a few riders would do the warm up lap at pretty much full speed (see above ;)), first corner, no problem.

Cold tyres will warm up on your warm up lap. Make sure you thrash the bike on the warm up lap.

that works, as demonstrated by Paul Payne at Pembrey ;) :lol:

yep - full tilt on the first race lap a must!! Races and places are lost in the first lap....

I generally ran 28/29 Front and 27/28 rear. But it is the warm pressures you are interested in, and that depends how you ride. I would aim for about 32/33 warm, and adjust the cold to suit. Controversially, I run with 1 or 2 more in the wet because I know I won't be generating the temperature to get the pressure up. Make of that what you will, because although I was 4seconds a lap faster than anyone else at a wet Oulton, I also fell off on my 5th lap!

(Did I mention I had poles, wins and fastest laps at more circuits than anyone else in Class B last year?!)

Dont remember you mentioning it, more info maybe ? :)

29 front and rear. wet or dry.

I like to keep it simple.

But I don't have as many wins, poles or lap records as Ron...

Thats more scientific than me! If they got air in then they are good to go! Ig I got the gauge out it was to make sure it were between 25 and 30.

You also fell off more than most also. :D

Senna3 28-Feb-2012 20:36

28 and 29 worked for me and that dident cause me to crash it was the riders falling of infront of me that did that :lol:

Although you do have as many track records as me.... and would probably have more if your bones were not made of glass ;) At least you will have an 1199 to take your mind of of it!

Anglesey - my fault
Pembrey - not my fault (and in practice anyway)
Cadwell - see below
Oulton - an act of God!

Tell me about it... I had 2 of you to try to avoid!

By your reckoning, that makes me God!!!

And I had nothing to do with you falling off at Oulton.

Jolley 29-Feb-2012 11:23

Haha! No... I meant my response to Kev!

But I always said you were a riding God... Just a fragile, occasionally grumpy God!
