Often overlooked, but very important to the balance and handling of your car. If you havent checked your pressures in a couple of weeks, go out an do it today - if you have been driving your Trophy hard, they will usually have changed.
Most people seem to use the following pressures:
Front: 32 32
Rear: 30 30
...however after a bit of research, quite a few of the more agressive drivers seem to use:
Front: 34 34
Rear: 32 32
...and those figures often go quite a bit higher on track days.
IMPORTANT NOTES:
If you havent checked your pressures since you got the car - you should ! mine were as follows, resulting in the car pulling to the right and risking a blowout:
Front 37 35
Rear 40 34
Tyre pressure should be checked when tyres are Cold after the vehicle has been parked for three or more hours, or driven less than 1 mile.
Buy a digital pressure guage ( http://www.autoexpress.co.uk/product_test/48123/tyre_pressure_gauges_dig.html )
...or a Digital Tyre Inflator (Halfords Rapid Digital Tyre Inflator got a very good review in TEST DRIVE magazine DEC05 £22, the MICHELIN HI-POWER RAPID TYRE INFLATOR won the review but it costs £38)
look carefully at the scuffing on the tread of the tyres. If the scuffing does not extend up to the edge of the tread then you need to lower the pressure by a couple of psi and if the scuffing extends onto the sidewalls then the tyres are too soft and require some more air.
...any more advise on tyre pressures is very much appreciated, including a guide for tyre pressures on a track day
