My fronts are more worn than the rears so they will need replacing soon. As I want to move away from Continentals to Pirelli I want to put P zeros on the front now. Any reason why this is a bad idea?

Cheers

Think I'd try and get part worns to tide me over, of the same tyre, then replace them all at once.

Or just do them all now

dont whatever you do mix tyre brands the car will reject them and self destruct, catapulting you into a lesser spec'ed car.

Whether it can really make any noticeable difference, I very much doubt, but Audi do state with Quattros that all tyres must be matching manufacturer, tread pattern and tread depth. As it wouldn't really have much affect on handling, I guess the worst case scenario would be that if you were in an accident, a very well informed and ridiculously picky insurance inspector might be able to use something like that as a reason not to pay out, because you're driving the car in a setup that's against the manufacturer's recommendation.

When I bought my S4 used from Audi it had mismatched tyre brands & tread depths, and when I pointed this out they shelled out £600-£700 for me to replace the tyres!

I believe it's something to do with having odd tyres causes a variation of the friction between wheels because of the different amounts of grip offered from different tread patterns and rubber compounds, so the diff tries to compensate for this all the time, rather than just when a wheel slips. This causes the diff to overheat.

(I think)

Thanks that has helped.
