tyre pressurei have

[jdearden]

i have just checked my tyre pressures and they are at about 36 psi. i have perreli p zero rosso fronts and brigestone rears. i was told that fronts should be 18 psi and rears 26psi is this right as this seems really low for such low profile tyres. my porsche that i had a p zero yres and where at 37 psi. a bit of clification on this would be great

I run 18/27. Some run slightly higher but certainly not 36

i have taken mine down now 19/28 and it is a completly different car. its great. much smoother and corners better

18/27 as per manual. I was concerned at first as to the low front pressure, but 5k in and not a blip with it.

As said, 18/27 is the spec.

That is for Bridgestones...the Pirrellis are 20/30.

OP, can I ask. Is the car a handful with those pressures?

It won't be a handful. It'll understeer a lot though, that's the usual effect.

18/27 are quoted pressures for the GTO3/3R (which was supplied with Bridgestones)
20/30 are recommended pressures for the M400 (which came with Pirelli corsa motorsport)

I'm guessing that is what Martin is referring to?

Thank you Conrad

Right, he has an M12, so isn't interested in M400 pressures unless his rubber's been modded.
