Please can any body tell me what psi i should have in my tyres. I have an 18 "inch wheel.

 

i run 32psi all round, 225/35 18

 

The ones on mine are 225/40 18

 

so are mine, don't know why i put 35

 

33 front 31 rear in mine

 

32F 35R is more like it surely? I might be wrong because Ive been struggling with pressures for another vehicle, but I believe so.

 

Usually higher for the fronts I think - 02 WRX Wagon is 33F 32R standard.

 

Yeah, a couple of psi more in the front.... Dunno why, but seems to be the accepted norm.

 

More weight from the engine over the fronts maybe?

 

Thats what i was thinking.

 

Have I got it the wrong way round? Thats come of fretting about 944 pressures for the last fortnight (29F & 36R).

 

I've been playing around with various settings over the past couple of months, and seem to have found:

29 F
28 R

...as the setting that seems to suit my driving style. You guys are running a bit higher pressures than me though!

I tried 32F/31R but the car seemed to understeer like crazy (on 17" wheels).

 

See thats the problem with Porsche all **** orver tit

 

I would have thought somewhere like powerstation would be able to give the best advice, what with all the geo set ups they do etc. Anyone friendly with any of the guys there and could ask?
Or Andy F etc if they have any opinion?

Im still trying to find the best for my 215 40 17 yoko pradas on a classic.
Currently trying 32 and 31.

 

ive always put 30f 30r and the car always seems to do what i tell it to.
