lust2luv Posted January 24, 2003 Share Posted January 24, 2003 wow, you've got turbos in your alloys?! I run a little lower on the rears in winter - around 33, but it's a personal preference. Link to comment Share on other sites More sharing options...

MONKEYmark Posted January 24, 2003 Share Posted January 24, 2003 what about my 21x25x195 and 21z20x205 is 33-36 ok i never check mine Link to comment Share on other sites More sharing options...
tDR Posted January 24, 2003 Share Posted January 24, 2003 I thought you stuck to the same PSI recommended by the manufacturer regardless of what wheel / tyre combo you've fitted cos the PSI figure is really for the car and means Pounds per Square Inch - you would need the same pressure of air in your tyres. So if it's 36PSI for stock rears then it's 36PSI for 19's 20's etc etc etc. Or I could have confused myself and be talking utter crap.... Link to comment Share on other sites More sharing options...
Supra_Al Posted January 24, 2003 Author Share Posted January 24, 2003 Ah good.............35 PSI in mine! Thanks Al. Link to comment Share on other sites More sharing options...
AJI Posted January 24, 2003 Share Posted January 24, 2003 Thunder : you are quite correct in your statement. The reason why people do change the pressures though is because with smaller tyre profile heights a lower pressure can give a slightly more comfortable ride, and also less 'twitchy' whilst driving. In wet weather some people may want to increase pressure to make the contact patch 'sharper' to cut through water on road surface. Just a personal preference thing in the end. Anything between 32psi to 42psi depending on what the limits are stated on your tyre wall. But I would try to keep close to 36psi on a stock setup ( stock suspension etc).
