Tyre Pressure

Recommended Posts

It's easier to do skids and drifts if the rears are up higher :)

I usually go 38 - 40 all round. It's sometimes hard to see a low profile tyre losing air.

I use 40 psi alround. Never really had issues with my tyres except when I got a screw in my rear left. Have any of you guys bought tyres online before?

Your service department's recommendation of 38 psi would be for the rear tyres. They are probably recommending what's on the tyre placard/Owners Manual, or slightly more. Even if you go by a car's placard, a higher pressure is usually recommended for the driving wheels.

Throughout my car ownership life, I have always over-inflated the tyres by a small amount. Automobile associations recommend about 4 psi over the tyre placard, while a driving course I attended recommended 4-6 psi. I currently use cold tyre pressures of 43 psi for the rear, and 40 psi for the front.

Thanks Malibu, I'll be sure to check them out. I have a good friend of mine who usually does my friends, family and my own tires but even though he did a good deal for me I still find them quiet expensive. He told me that the rear tyres on the Isf are a unique size to the Isf and the Audi TTRS.

Hi Marvin

Everyone to their own but have you considered going with a wider tyre i.e. 265 or 275. This is still ok for the std 9" rim and has been done on many ISF's. I have gone 275x30x19 Michelins - not an available size in Oz. s just under 1 week to get here.
