Guest Supracar Posted November 6, 2006 Share Posted November 6, 2006 Further to my current thread: 'Steering wheel vibrates at 70mph ????', can anyone advise me of the correct tyre pressures?My fronts are 235/40/18 ZR My rears are 235/35/18 ZR Link to comment Share on other sites More sharing options...
Ian W Posted November 6, 2006 Share Posted November 6, 2006 34-36 appears to be the general concensus (36psi all round is stock iirc) Link to comment Share on other sites More sharing options...
AlanM Posted November 7, 2006 Share Posted November 7, 2006 36 should be fine, I tried 38 found it a bit hard. Why you running larger aspect ratio (smaller diameter) on rear? Link to comment Share on other sites More sharing options...

Why you running larger aspect ratio (smaller diameter) on rear? well spotted Alan. must be a typo i'd think, i would imagine it would be a wider tyre but with the 35 aspect ratio...i hope!

NUTKIN Posted November 8, 2006 Share Posted November 8, 2006 Hi im a mechanic an just read your statement u really should have wider tyres on the back the mitchelin book at work states that 265's should idealy be on the back just thought id let u know which should give it better grip an looks better in the arches.

Ian W Posted November 8, 2006 Share Posted November 8, 2006 do you really drive a supra with 235's at the back ???????? even the stock size it wider than that mate like i said before, hopefully this will be a typo as the aspect ratio would be wrong also meaning he has a smaller rolling radius on the back.

Guest Supracar Posted November 8, 2006 Share Posted November 8, 2006 I've only had the car a week, these are the tyres that were already on it. What would be better? Link to comment Share on other sites More sharing options...
Ian W Posted November 8, 2006 Share Posted November 8, 2006 I've only had the car a week, these are the tyres that were already on it. What would be better? what are the pressures that were already on it? it's not the pressure we're worried about, it's the size of the tyre!

Nic Posted November 9, 2006 Share Posted November 9, 2006 What I meant was, what tyre SIZES would be better? What width wheels do you have front and rear, as this will determine the tyre width you can run? Link to comment Share on other sites More sharing options...

Sorry, my panic is over, it does have 265's on the rear... Link to comment Share on other sites More sharing options...
