    Hi All,

    I have fitted to my Audi A4 (B6) 1.8 T-Sport Cab a set of RS6 reps 19" in size with 235/35/19 tyres.

    Does anyone know the correct tyres pressures front and rear ?

    Cheers
    James

    I'm using 42 all round until advised otherwise, I started a similar thread a few week ago.

    Initially I thought 42 may be too high but car behaves well and this is also the listing for 18" fuly laden so maybe the wheel shop I used were correct ?!?

    When i bought mine from wheelbase in oldham they reccommended to run standard pressures as the car still weighs the same wotever size you got on there, does seem to make sense though, however it does contradict wot the tyre pressure sticker stipulates as it has reccommended for different wheel sizes.:notme:

    :icon_thumright: :icon_thumright: :icon_thumright: Can anyone explain why we presume we need more pressure in a bigger tyre. Seems to be a black art. As a lorry rides round on 28" rims per say and probably has 25 times the volume of air in but probably on 35psi.???????????So why do we all presume just cos we got a bigger tire we need more pressure?????

    Juss only had wheels fitted 3 weeks ago and they reccommend to use the standard pressures i was runnin my 17s, so ive been deliberating what to, and to be fair i still dont know what to do, may give a few wheel and tire specialists a bell tomorrow and see wot they say. Of course people who have already worn a set of 19s out and replaced them would be our best help as we all know overinflation and underinflation cause abnormal tire wear, these guys should know by there tire wear whether they were running good pressures or not.:weight_lift2:

    Can you ask about new 18's also, it would be good for myself and others who are in the process of buying 18's to know what the correct tyre pressure should be - thanks

    The tyres have a rough guide of inflations, maybe a max limit, but the trouble is the tire doesnt know whether its on 1 ton car or a 2 ton car so it doesnt really count for a lot to be fair, you should always stick with car makers pressures or thereabouts.:)

    Right gents ive done some research this morning as promised and im here to put this little puppy to bed, i phoned three major car tuners/tyre and wheel houses namely Demon Tweeks, Elite and Wheelbase, they all came back with the same answer : Run standard pressures of your original wheels and tyres as the the car weighs the same as it used to and therefore requires the same pressure : Also you guys need to stop using these petrol station tyre pumper uppers as all them things get day in day out is knocked about to hell, then they get run over by a dirty great transit van and give total innacuracy and are inconsistent from week to week. I would strongly advise you guys get yourselves a good quality tyre pressure guage be it digital or not, and at least this way your guaranteed consistency, there not expensive. Also never trust the guages that are fitted to footpumps as there a total load ********. Hope this helps guys.......:hi:

    Im now presuming your yankin my chain, anyhow these are the pressures you squirrels should be runnin on 17s, 18, and 19s....................
    Everyday usage:-
    Fronts 32psi
    Rears 32psi

    Full of people + luggage:-
    Fronts 38psi
    Rears 38psi



    The above pressures are for an Avant TDi, couldnt tell you whether there the same for saloon and petrol models. For those of you with saloons and petrols the information can be found by the drivers door catch.:gun2:

    No.In my fuel fillerdoor it gives 2 different pressures depending on what size tyre the car has.

    This is true, the smaller wheel size pressures in there are for non low profile tires, the other pressures are for low profiles, you need to follow low profile guidelines.

    this is nonsense - the fuel filler cap seems to contradict the "professionals" by quoting different pressures for different tyres. why is such an important topic so confusing, especially given the possible safety and enviromental implications?
