Tyre Pressure - whats yours?

For general Technical and Performance Discussions

Postby Nanna10r » Fri May 04, 2007 7:39 am

Depends on tyres/bike/use.

Oh & dont forget construction considerations. Better built tyre needs less pressure to work better for Nana's like myself.

I usually start with 34 - 38 & settle at 32 - 34.

I checked the beemers tyres this morning after it felt a little rubbery on the way home last night. Naturally enough, 19psi in the front and 22 in the rear! Perfect! :lol: Yeah...so I added a few to that! Didn't really change the bike much but! still feels rubbery! :lol:

I had a few rear tyre slides when I was running 38 in the rear with powers, haven't had that with 36 though.

I found out running 36F/48R gives good milage and less drag so it feels lighter.

Just brake plenty before corners :D

Andi, most tyres have a maximum pressure rating! ie; the max amount of air alowwed to be stuffed into it. I have a strange feeling 48 Psi, may well exceed that! You run the risk of the tyre tearing from the inside out! :wink:

Well, at the moment I'm running 32F and 0R on the Zed. :cry: That made me discover that Marranda was running 21F and 24R.. :wink: (Gotta love multiple bike households!)

Now the ZX6R is comfortable on 32F 34R. 8) Z is still 32F and 0R.. :evil:

The normal pressure recommended on the J1 is 42psi. I found this to be too soft due to very plush suspension. I increased the pressure gradually and found 48 to be the most confident inspiring ... with exception on bumpy roads e.g. gippsland. It's so much less of tyre drag that it kept up with new gsxr750 on a stright line :D

Hmm that's bit worrying if it tears up from the inside but my understanding a tyre can withstand 3x the recommended pressure ?

mate seriously, 48psi on the rear is mental. every tyre is diff so i can understand the psi can differ but 48???? sure it might feel better and lighter but you are more likely to stack it around a corner.
im not telling you to change it but just be careful

Depends on a lot of things, for the road it doesn't matter that much but when on the track you should try and get it right. Read a few articles about reading tyres or speak to a suspension/tyre guy and then adjust accordingly. Can come down to just 1/2 psi between getting it right or wearing out a tyre in 20mins for some brands.

I've been running my track bike (SV650S) at 30/30 (cold) with Pilot Power's although I've been thinking of upping it to 32/30 (increases stability when cold).

For the road I'd prob run 34/36.
Motorcycle's are inherently unstable... :twisted:
