paulj1 Posted September 23, 2010 Share Posted September 23, 2010 Hi I'm running 235/40/18 on the front and 265/35/18 on the rear but never been able to find out what pressure they should be at any help guys would be greatly appreciated Link to comment Share on other sites More sharing options...
Dnk Posted September 23, 2010 Share Posted September 23, 2010 (edited) Stock tyre pressures on a UK spec are 36 front and 36 rear, I use the same pressures in my 10 x 19 fronts and 11.5 x 19 rears and am quite happy with tyre wear etc. You'll get lots of varying opinions on this topic and will probably be more confused than before you asked Edited September 23, 2010 by Dnk (see edit history) Link to comment Share on other sites More sharing options...
paulj1 Posted September 23, 2010 Author Share Posted September 23, 2010 lol thank you Dunk I've been running them at 32 all round as that's what tyre place did them at I'll go put some more wind in them Link to comment Share on other sites More sharing options...
adam1983 Posted September 23, 2010 Share Posted September 23, 2010 I put 34 in mine all round on 19s but like yourself i was a bit unsure what i needed. It seems fine though and most people on here have more or less the same im guessing Link to comment Share on other sites More sharing options...
Geo Posted September 23, 2010 Share Posted September 23, 2010 34psi running my 18's Link to comment Share on other sites More sharing options...
AlanM Posted September 23, 2010 Share Posted September 23, 2010 36 all round on 18s Link to comment Share on other sites More sharing options...
Dnk Posted September 23, 2010 Share Posted September 23, 2010 (edited) I think most of us wouldn't notice much differance from them being at 34 or 36 psi. It'll show up in tyre wear though but then its usually too late. Same goes for running too much toe and camber !

Gaz6002 Posted September 23, 2010 Share Posted September 23, 2010 Use trial and error to find the best pressure for you. Link to comment Share on other sites More sharing options...
Pixelfill Posted September 23, 2010 Share Posted September 23, 2010 usually 35 for me 235/40/18 265/35/18 Link to comment Share on other sites More sharing options...
Luxluc Posted September 23, 2010 Share Posted September 23, 2010 (edited) What tires are you running .. street tires or semi-slick? I had 35 psi in my street tires, and 28psi in my semi-slick now (both values when cold).

Terminator Posted September 23, 2010 Share Posted September 23, 2010 Nics post shows the manual figure, yet my door pillar sticker clearly states 2.5 bar front and rear. Even Toyota are confused. Link to comment Share on other sites More sharing options...
Nic Posted September 23, 2010 Share Posted September 23, 2010 Nics post shows the manual figure, yet my door pillar sticker clearly states 2.5 bar front and rear. Even Toyota are confused. I think the manual is a US version, which could account for the difference. Link to comment Share on other sites More sharing options...
Graham S Posted September 23, 2010 Share Posted September 23, 2010 On my old UK, the tire pressures on the sticker says 36psi all round. Link to comment Share on other sites More sharing options...

Terminator Posted September 23, 2010 Share Posted September 23, 2010 So that's why the Americans seem to go faster, more grip. Link to comment Share on other sites More sharing options...
Jellybean Posted May 28, 2012 Share Posted May 28, 2012 Might as well resurrect this thread Does anybody know what Steve and Paul Whiffin run in time attack; I am sure they will know the correct pressure after all the laps they have put in! Nic, do you have the Toyota Service Data for the Alignment ; the image got cut off thanks! (maybe make it a sticky) Link to comment Share on other sites More sharing options...
Dnk Posted May 28, 2012 Share Posted May 28, 2012 36 PSI Hot all round so approx 33/34 from cold for rd use Track pressures will be a little differant as they will gain more pressure due to the tyres and brakes working much harder than on the rd Link to comment Share on other sites More sharing options...

Thats great but my car is a Toyota Supra! From what I can see my rears are wearing evenly, my fronts however are not bad for 5 years but I am getting the tracking checked Link to comment Share on other sites More sharing options...
TubbyTwo Posted May 28, 2012 Share Posted May 28, 2012 Im 34 front and rear from cold. Link to comment Share on other sites More sharing options...
Jellybean Posted May 28, 2012 Share Posted May 28, 2012 Im 34 front and rear from cold. Thanks, I think I will go with 34, my friend is running 32 in his R33 Skyline so based on that I reckon 30 is far too low for a Supra Link to comment Share on other sites More sharing options...
