What tyre pressures are people running, mine seems to be a bit crashy on the front, thinking maybe a little low

[terminator x]

I just run what it says on the door cill, 38 all round from memory.

Does it make a difference if you have 235/35s all round or staggered?

Try as a starting point running the pressures as on the sticker in the drivers door shut.

 

I run 235/35-19 on all 4 corners at 45psi all round & my tyres wear evenly on my 8P.

^^^^^^+1 for the Door sticker.

They’ll vary any way as the tyres heat up / cool down constantly.

[Oldmanracing]

Yup door sticker values and pumped up to the max Regardless of load, how many people you normally cart about.
And remember to check regularly temperature and pressure are relative, laws of physics and all that.

I find that after I check and add more pressure it sharpens things up quite noticeably

One of the cheaper (free!) and easy measures to take that improves performance

At the advanced driving day I attended the Audi Lead Instructor said to run the RS3 on the road at the "maximum" (as in the pressure for a fully loaded car) as it feels more alert and the chassis is set up for that. Didn't matter if staggered or square setup he said.

I used to find the front would struggle for grip when cold and would "slap" on expansion joints badly at the higher pressure though. Swapped to MPS4S tyres and its almost perfect now and always precise and forgiving on broken tarmac at full pressure.

I’ve never understood the need to ‘play’ with tyre pressures if I’m brutally honest.
The sticker is there to guide us so in my opinion that’s what I use.
As the above post, the car has been setup / fine tuned on these pressures.

Why people think they know better when Audi have given the precise info is beyond me.

According to TPMS, mine came with 42.5 on the back and 37.5 front.  Seems pretty solid.

I'm running MPS4s also   In the wet,dry,hot or cold i just can't fault them with the higher tyre pressures. 

 

I did a 20mins track session at Castle Combs RSFest last year & afterwards the MPS4s looked like new mate.

I have the rs performance pack with the staggered tyre sizes and bugger me the door sticker could not be more confusing if it tried.

Anyway, I had a tpms light saying front right was flat (it wasn’t ) but gave them all some air and it absolutely transformed the handling. They were all down about 6-7psi from suggested after only a few months of owenership. Now back to 39.5 front and 36.5 rear and feels great.

If you track your car drop it down a good margin as you’ll be amazed how quickly pressures build up. Although if you track your car this is probably telling you what you already know.

[Oldmanracing]

I check mine weekly..... it's all to do with the temperature.... (basic physics, temperature and pressure and relative) people forget that.
Recently it's been hovering around 3 degs, and mine needed a puff when checked.

Your right about track use, needs monitoring and adjustment,

it's findimental and a lot of people seem to ignore it, and makes such a difference....


OMR (tyre pressure OCD)

[Comfortably Numb]

Nitrogen is the way forward.

Checked mine today as the Tyre Pressure Indicator came on on Sunday. Now as the car is only 2 months old I thought the pressures would be somewhere near the recommended as shown on the sticker...

WRONG..

 

33 psi all round!

 

So I've gone for the 39 front and 35 rear for now....

[Oldmanracing]

It's a moving target, temperature is everything

[robokn]

Currently running 44 all round seems to work a treat

[Evil Diesel]

The pressures seem to be all over the place from the factory. My last one (delivered in December) had 35psi front and 37.5 rear. The new one has 40.5 psi all round.

 

They both seemed pretty solid tbf.

They should be checked & inflated to Audi spec on the PDI at the dealers before delivery to the customer.

Checked mine this evening and it’s 39 front and rear.

[drgav2005]

Does anyone have a picture of the door sticker that shows the OEM staggered setup: 255/30 front and 235/35 rear???

 

In Audi's quest to make life easy, I checked my door sticker but given I'd gone for the standard setup this is all that was one them...

 

 

I then thought RTFM!!! And I did, and there are no values given in the book - doh!

 

Given I've moved to the new setup I'd like to know what Audi recommends. I'm currently running 39 front and 35 rear on the MPS4S tyres...

 

Thanks in advance!
