PANACEA Posted August 19, 2006 Report Share Posted August 19, 2006 Hi all, Recently swapped the wheels/tyres on my 2004 A4 Q Sport 190 saloon from standard Star alloys to S-lines 5 spokes with 235/40 r18's and just wondered what pressures these should be at, as the manual and the sticker in the door frame doesn't quote pressures for this size of tyre, as they obviously weren't standard fit? Have tried a search but cannot find what I need and Audi have quoted me three different pressures !!!!! Thanks Link to comment Share on other sites More sharing options...
kite Posted August 19, 2006 Report Share Posted August 19, 2006 I run mine @ 36 psi Link to comment Share on other sites More sharing options...
Milo Posted August 19, 2006 Report Share Posted August 19, 2006 Ditto. 235/40/18 on mine are 36 all round. Link to comment Share on other sites More sharing options...
PANACEA Posted August 19, 2006 Author Report Share Posted August 19, 2006 Thanks guys, but really need confirmation from someone with the 1.8T 190 engine as I presume that this is lighter than the Diesel engines, and therefore may be slightly lower. Unless Milo has this engine of course !! Cheers. Link to comment Share on other sites More sharing options...
Milo Posted August 19, 2006 Report Share Posted August 19, 2006 Mine's the 2.0T 36 will be fine. Link to comment Share on other sites More sharing options...

[/ QUOTE ] You're ok fella My car is a 190ps 1.8tq with 235/40R18's and pressures are - 36psi all round, normal laden 42psi fully laden I run them at 37 (one for luck ) and tyre wear is excellent and even (P Zero Rossos) BUB Link to comment Share on other sites More sharing options...
PANACEA Posted August 19, 2006 Author Report Share Posted August 19, 2006 Perfect....many thanks all. Link to comment Share on other sites More sharing options...
iceman2002_uk Posted August 19, 2006 Report Share Posted August 19, 2006 tyre pressures should be either on back of your fuel cap or on the drivers door pillar Link to comment Share on other sites More sharing options...
PANACEA Posted August 20, 2006 Author Report Share Posted August 20, 2006 Yes,they are on the door pillar, but as I have changed the alloys to S-Lines, the sizes on the door pillar no longer apply to the tyre sizes on the car. They start smaller and go to 235/45x 17 but not to 18's !! Anyway, got them off the guys above now so a happy camper. Link to comment Share on other sites More sharing options...
pitch3110 Posted August 22, 2006 Report Share Posted August 22, 2006 39 all round, bit more if i am out on a run Link to comment Share on other sites More sharing options...
iceman2002_uk Posted August 22, 2006 Report Share Posted August 22, 2006 are the pressures in the back of the handbook not applicable to all models, ie arent your new tyre size listed??? Link to comment Share on other sites More sharing options...
PANACEA Posted August 23, 2006 Author Report Share Posted August 23, 2006 Nope......only goes up to the sports tyre size of 235/45 x 17....I guess because onlt the S-Lines and above had 18's, then they will have the larger size, but my sport certainly doesnt and neither does the handbook which surprised me a bit !!
