Wheel swap front to rear

If I swap my wheels front to rear (square set up) to try maximise tyre life will it cause me any issues with the tyre pressure sensors ?? As in would they need to reset or could it show that front is losing pressure but it’s actually the back as the sensors are not in there original location ?

Shouldn’t be a problem at all as long as you reset pressures and mmi..

However personally I’ve never swapped fronts to rears etc to get extended wear time as IMHO a tyre is worn to the suspension corner, and swapping front to rear (or vice versa) *could* initially take a little while to scrub in as camber and caster will differ..

Also depending on how much they are worn you run the risk of reducing grip or front or rear..

All imho of course as inevitably you will end up buying new tyres anyways either 2 then 2 or all 4 at the same time .

This is something I do on mine, however I have the PFL model and the tpms is not as advance as the FL models one. All I do is reset the air in each tyre to the required pressure and store new values on the MMI unit.
Same as mine then cheers man

On my S3 I regularly swop wheels front to back and winter wheels to summer wheels.
After each time I reset the tpms.
I prefer wearing all together and replacing as a set of 4.

I’ve never swapped front to rear for the reasons mentioned. S3 wear on same Pirelli PZero is much better than RS3. Fronts wear more quickly and it may be a case of buying 2 tyres at about 18000 miles.

Apart from buying a new set of 4 with a set of aftermarket wheels on my Golf GTI, I've always bought 2 tyres at a time and put these on the rear whilst swapping the part worn tyres to the front (irrespective of driveline). Mainly for the following reasons...

1. It's what's recommended by most tyre manufacturers (to alleviate the problem of the most amount of grip swapping ends)
2. You end up buying 2 tyres at a time rather than 4 - whilst I could afford to do so, I'd rather not have a £600 bill in one go on top of normal servicing etc.

That said, I've never had a TPMS system that uses sensors. All the VAG one's I've had use the ABS sensors to measure wheel rotation speed so it's as simple as resetting the system.

Swap front to rear. No issues. Just reset your tpms. Don't buy 2 new tires and only change 2. Horrible advice on an AWD car.

How exactly does the ABS sensor know what the tire pressure is?

It doesn't. In simple terms, it knows the circumference of the wheel/tyre when you set it in the MMI. Any loss of tyre pressure will affect the circumference and the ABS sensor on that wheel will sense the difference.

So in the same sense, if you pump up your tyres more, (say if you were fully loaded up), and didn't reset the MMI, the same tyre pressure warning would come up.

Technically swapping front to rear and vice versa came about years ago for FWD and RWD cars to ensure the best grip was at the drive wheels ..

The advice for AWD cars is to regularly alternate tyres around to ensure equal wear and grip. Edit: I believe Audi suggest 10k or annually

I can’t imagine AWD tyre wear is as extreme 2WD anyways, Not saying anyway is better than the other, but swapping extreme grip levels from front to rear would scare the crap out of me..depends if you prefer understeer or oversteer ?

and let’s not forget the wear in period (camber/caster) until full contact is made with the road.

Each to there own. Advice on a forum shouldn’t always be taken as gospel when safety is at stake IMHO

All I'm saying is ive been driving audis for years and regurally swap wheels. I track my car and drive it hard. The one thing I don't do is cross rotate. Only front to rear. Never had an issue other than a bent wheel causing vibrations through the steering wheel when it was up front.
That being said. All cars are not equal. I encourage you to push your car to its limits in a deserted area or track. No need to go fast, just feel where the break away is at. Then rotate the tires and repeat. Who knows. Maybe you'll get the answer you seek.

Pavement or dirt, doesn't matter, it's about how you drive
