S1 pressures

[jimbo]

Don't have a handbook to check. What tyre pressures should my s1 111s be running? I've always had 25 front and 26 rear?

Cheers

23 front
27.5 rear (if 225)

24.5 if 205 (does anyone use them anymore!)

However...also depends on type of tyre. Those settings were for OEM PIrelli P-Zeros back in the day. I tend to run my Toyo T1-Rs a couple of PSI harder than that, helps offset the softer sidewalls.

Set em up, go have a play, then change em and try again.

The biggest impact is varying differential between front and rear...you can induce some amounts of over / understeer through this, I'm told by an old friend...

Tends to be personal choice as well - I always ran the rears 2psi higher than the fronts and used the fronts as the barometer. Set pressures to get the steering weight I wanted, then stick rears 2psi higher. On the 48s, that ended up between 20f/22r and 24f/26r on the road, dependant on what I was doing.

More a personal choice/set up tool than a simple right/wrong though (within reason)
