Tyre pressures
 

what pressures are you running in the dry and wet!!! 620s


Thanks

pretty sure most are running 65 front and rear in the dry, obviously slightly more in the wet to make sure the tread stays open.

That's where we differ Dickie.

I'm running 5psi front and rear ;)

Need to get the tyres real hot, plus it gives your more grip in gravel traps.

65 dont think i fancy that!!

was thinking 30 rear 32 front dry

34 rear 34 front wet?

think that might be a little to soft for me!!!!lol

Honestly, I run 30/30 in all conditions. Although if the tyre guage says 29psi - that's good enough for me!!

Don't forget we're tractor racing on standard road rubber :D

30/29 for me. may up it a couple in the wet but doubt i notice the difference anyway.

Thanks guys...will try that out on friday!!!

You don't want to run it too low on wet tyre as the thread blocks can close up at the contact patch and diminish some of their ability to dispere water. I run 36/36 on my wets, but ask one of the race tyre dudes. Also, Michelin technical support is excellent for such questions.

Ian is running Pirelli Diablo's Felix ;)

It's a DD bike :)

Ah well, should pay more attention as to which forum I am looking at.

It's worth having your pressure gauge checked out from time to time against a known calibrated/certified gauge. If its out at least you know how much to compensate by.

A simple check that is easy to do especially for the digital type gauges is one of repeatability.

Take three readings one after the other, are they all very close? if so, OK, if not, yer gauge is a random number generator:o

A mate did this once with his digi gauge and got readings that were 7 PSI apart. Tried a new battery and still the same, bin fodder.

Ray.

I must be getting old, because seemingly I can't get myself to trust those digital jobbies.
