Taken from the label (drivers door post) for 225/40 x18:

Light load = front 33 rear 31

Heavy load = front 36 rear 35.

34/33 seems to work best for me... :)

Steve_PPP 27-03-2010 09:00 PM

I would have thought so, but classics are lighter than the newage scoobs.

The figures I quoted are from Subaru for the WR1 which I believe was the 1st to have 18s as standard . ( I could be wrong on that though )

i tend to run slightly higher pressures as i'm hoping it might reduce the chance of damaging the rims on potholes!

When I first fitted mine (classic wagon), and had Prodrive geo settings done by TSL, they recommended pressures of 35 F and 32 R, and they seem to have been fine over the years.

:SMBLU:

Guys don't trust the tyre gauges at petrol stations or in fact tyre fitting places. I brought a digital gauge after using big e,s one. Petrol station gauges both analogue and digital type as much as 4 psi out, I had 2 new tyres on font of m3 on Thursday, there gauge was 3psi low. M3 is a pain as you have to have oposing tyres even or bloody tyre pressure warning light comes on

BIG"E" 28-03-2010 12:12 PM

Dont forget, tyre pressures go up with hard driving.

Peoples that are going to The Ring should ideally do a sighting lap, then pull over and check your pressures and reduce if required.
When I went round last year, the rear end grip started to lesson as the tyre pressure increased.
The same goes for the track IE Brands Hatch in April.:nod::drive::drive::drive:
