Is there a sticker under your front boot lid? That's where ithe info is on mine. It should be 29F 36R for all wheel sizes if I recall.
 
Question please. I have 18" Carrera wheels on my 986, Dunlop ZR 18 Sport 9090 tyres, 265/35 on back and 225/40 on front. Can't find them on Dunlop website but wanted to check pressure guide. Boxster handbook is based on 17" rims. Does this make a difference?

Thanks

Pete
 
I've got the same wheels on my 986, (but with Michelin Pilot Sports), and the pressures are 29F, 36R as Mark suspected. The tyre pressure info sticker on mine is inside the drivers' door opening, just above the latch.
 
All this talk of tyre pressures has got me wondering: where/how do I get hold of a pressure gauge that is accurate? Those built in to most cigarrette-light socket compressor thingies are useless since they max out at 200 or even 300psi, so telling the difference between 29 and 36 is almost impossible. Even 1 or 2psi will make a difference to these tyres and at circa £200 a pop, you want to get it right!
 
I got a good analogue (dial) display one from a motor racing supplier (either Demon Tweeks or Grand Prix Racewear) Analogue is more accurate in this case as the digital ones only show to the nearest 1 lb, or 1/2 lb, whereas you can see that it is spot-on or not with a dial.

That's more like it. [link=http://www.demon-tweeks.co.uk/products/ProductDetail.asp?cls=MSPORT&pcode=LON50401]Longacre 0-60psi[/link] with a nice white dial and a rubber surround for about £26 inc VAT and postage. Thanks, Mark.
