SO3 Tyre pressures

[herbie hammer]

I've got SO3's (225/50 ZR16's) on the rear of the Chimaera (4.0) and was wondering what pressures everyone else is running on at the moment.

Not 100% sure about the 225/50s, but the 245/45s are supposed to run at 24psi (22psi for the 225s on the front).

I've got SO3s all round and run 20 front and 22 rear.
Seems better than original pressures of 22/24 and they wear evenly.

Yep 2psi lower all round to compensate for the stiffer tyre wall. Builds up your shoulders at parking speeds too!

Not if you have PAS - which is a definite advantage.................

I tried a marker pen over the tread for a few miles and looked at what got rubbed off. I found 21 front and 23 rear to be he best for wear on S03 tyres (Now on Eagle F1). What that relates to on grip is anyones guess !

I find the non-PAS gives more feedback at speed but is a pain with 225s at the front at parking speeds (Now reverted to 205s). The PAS on the Tuscan means it turns in more quickly and can sometimes feel too light - not tried PAS on a Chim though.

Thanks - will give these a go and see if I can get an optimum setting on mine
