Supra_Al Posted May 7, 2003 Share Posted May 7, 2003 I was unfortunate last night to get a cross head screw in my new rear tyre Thought the car seemed to 'wobble' a bit on the way home!.............just had it repaired. What is the correct pressure for a UK TT rear standard size tyre 255/40/17 as i had to guess at 32 psi.......anyone. Al. Link to comment Share on other sites More sharing options...
Bobbeh Posted May 7, 2003 Share Posted May 7, 2003 According to the sticker on my car, its 36psi on every corner. Link to comment Share on other sites More sharing options...

Terminator Posted May 7, 2003 Share Posted May 7, 2003 Thats what is says on the pillar 36 all round. I run 35psi front and 34psi rear and get very even tyre wear across the tread pattern and good grip. Link to comment Share on other sites More sharing options...
Patrick_Devlin Posted May 7, 2003 Share Posted May 7, 2003 I've run 36 on the back for the last year and have just noticed excessive wear in the centre of the tyre... Link to comment Share on other sites More sharing options...
SimonB Posted May 7, 2003 Share Posted May 7, 2003 My jap spec handbook thingy says 33psi all round for 17s. Maybe because it's hotter in Japan that here ? (Edited because my memory is bad and it actually said 33psi, not 31 as I originally said...) Link to comment Share on other sites More sharing options...

Your rear tyres last you more than a year ?!!!! Link to comment Share on other sites More sharing options...
Terminator Posted May 7, 2003 Share Posted May 7, 2003 Originally posted by SimonB My jap spec handbook thingy says 31psi all round for 17s. Maybe because it's hotter in Japan that here ? The temperature should not make any difference as long as the tyres are at ambient air temperature when pressures are measured. AFAIK. Is the Jap book thingy an original or a translated jobby.

They're BFGoodrich. Had them on there for 18 months actually. Obviously not driving the car hard enough. I shall rectify that immediately Link to comment Share on other sites More sharing options...
AJI Posted May 8, 2003 Share Posted May 8, 2003 I find that running around 34psi gives even tyre wear on 285 width tread. fronts are still at 36psi and are wearing evenly on 245 width. on stock widths I would say stick to the 36psi all round as stated on the door beam.

JCresswell Posted May 8, 2003 Share Posted May 8, 2003 I Run 31 rear 30 front, on cold tires, as they heat up air expands blah blah blah, and a little soft means mors grip! when there hot.... never use recomended psi unless its long distance!

SimonB Posted May 8, 2003 Share Posted May 8, 2003 Is the Jap book thingy an original or a translated jobby. It's an original, here's a (very crap) scan : http://www.simons-house.freeserve.co.uk/tirepressures.jpg But it actually says 33psi (well, 2.3 kg/cm2 anyway), not 31. So much for my memory, good job I look at it before checking pressures really. Of course it might actually say "Whatever you do, don't inflate the tires to 33psi"...
