Tyre Pressures
I've had a search but cannot find any info that answers my question.
I would like an idea of what to run cold for a Fury (460kg) on 15" A048 and R88 Tyres for road and track applications
Thanks
Chris

You really need to check the temperature across the tread and get as near the same as possable using diferent pressures untill you achieve it, this
will achieve the flatest tread contact with the road. Buy your self one of those temperature sensors, usually fairly cheap on the bay of E. I did it
with mine, (which is MUCH heavier than yours), and found 24 front and 26 rear was perfect for equal heat/flatest tread. HTH Ray
To make a car go faster, just add lightness. Colin Chapman - OR - fit a bigger engine. Chippy

I agree with Chippy but I think you will end up at about 18 psi for your car

I can not answer for 15" wheel/tyre combo, but my 13 X 205/55 work the best at 16psi

I would say its very dependent on your set-up but if you look at the manufactures spec it is around 20-24psi if i remember correctly. I do not think
you should run tyres under-inflated the suspension should be doing the work.
here is the link for info.

a bit more for you.
Tyre Pressures
Probably the most important thing to check regularly, making sure they are the same as the manufacturers recommendations.
An under inflated tyre can overheat, wear out the shoulders of the tread quickly, puncture easily and give a poor handling car, with slow and heavy
steering. An over inflated tyre wears the tread centre faster, can overheat and makes the steering feel light and vague, again giving a poor handling
car.
Tyre pressures should be checked when cold and kept to the recommended pressures. We have a large range of tyre pressure gauges, compressors and a
tyre pressure monitoring system, so there's no excuse for not checking them regularly ! The most cost effective way to start improving your cars
handling.

Cheers for your replys people, I have a temperature sensor already and am used to setting up my tyre pressure on my old track car, but haven't
got it to track yet so was just looking for a ball park figure to start from really.
I'm not keen on the 15" wheels it train tracks like mad on road and think I will be changing to 13" some time anyway.
