Robbo Posted November 23, 2006 Share Posted November 23, 2006 I have got 18" Buddy Club P1's on my N/A. What are the correct tyre pressure's. I have been putting 30 in all round as that is what the garage I bought it off told me to put in, is this correct? Link to comment Share on other sites More sharing options...
michael Posted November 23, 2006 Share Posted November 23, 2006 I little low IMO, 35 all round with a few PSI adjustment either way until you find a setup that feels the best. I use 35 up front and 33 at the back currently. Link to comment Share on other sites More sharing options...

Alex Posted November 23, 2006 Share Posted November 23, 2006 Personally I keep them a little soft in the winter...Maybe only 30psi in the rear and 32 up front... Link to comment Share on other sites More sharing options...

Way to low! you'll prematurely wear the tyres out 2.6 bar all round for me .. whatever that is in psi ?? Link to comment Share on other sites More sharing options...

Graham S Posted November 23, 2006 Share Posted November 23, 2006 in the toyota handbook it states 36psi all round, but not sure if your suppose to adjust that for different sized tyres/wheels? Link to comment Share on other sites More sharing options...
Robbo Posted November 23, 2006 Author Share Posted November 23, 2006 I'm confused now then, what tyre pressure's shall i use Link to comment Share on other sites More sharing options...

Alex Posted November 23, 2006 Share Posted November 23, 2006 It tends to be a case of trial and error when using non stock wheels/tyres. You need to run them at a set pressure for a few months and see how they are wearing...but this is also a factor of the geometry setup on the car... I think you should try increasing the front pressure by 2psi to overcome the extra weight over the front. I'd leave the rear tyres at 30psi in winter as this gives you a bigger foot print and more mechanical grip. So 32psi Front and 30psi rear. In the summer I'd go for 34-36psi Front and 32-34psi rear. Don't go any higher than this because when the tyres warm up they increase in pressure...for example say you are running 36psi cold, after a run you could see an increase of 4psi, as the air inside has heated up and expanded. Manufacturers limits are about 44psi, and there is absolutely no reason why you'd need the tyres stressed to this sort of pressure. But like I say you'll have to do some trial and error to see what you like most. Link to comment Share on other sites More sharing options...
Kranz Posted November 23, 2006 Share Posted November 23, 2006 Another way to do it is to go for a hard run and then check the tyre surface temperatures with a pyrometer. Even temperatures across the tyre face indicates a correct pressure. Pain in the arse to do though! Link to comment Share on other sites More sharing options...

Sheefa Posted December 26, 2006 Share Posted December 26, 2006 Jesus, just searched for tyre pressures as haven't got a scooby about what I should be topping mine up to in this weather............ .........and then I came across your website Claire (Robbo) Holy mother of god you're fine. Good luck with the modelling, seems like you're doing pretty damn well already though! Greg Link to comment Share on other sites More sharing options...
