Tyre Wear

[chris200100]

I have a Cayenne 3.2 with 20" wheels I had a new set of Pirelli P-Zero Rosso (275/40/20) tyres fitted at the end of aug last year, I checked them the other day and they are now all on 3-4mm I have only done 4405 mile since fitting and I don't drive it hard is this level of wear normal???
I've been back to the tyre fitter and he gave me the brush off and Pirelli don't seem interested.

If this is normal wear on this type of tyre what tyre is best for wear and do they need to be porsche 'N' spec tyres??

It think I've read on here that Pirelli P-Zeros start with less tread than most other brands. >>I don't drive it hard<< That's what they all say[]

Chris ........ I'd say not. My 3.2 running the same tyres -- 90% motorway driving returns - 25 to 30K with slightly more wear in the centre.

I thought it wouldn't be normal for the to wear so quickly, I mainly do town driving with little motorway, my main journey is only 2.5-3 mile each way lots of stop start but I can't see how that would affect the tyres that much.

I have a KNS with 20" rubber. The outer fronts have become slicks after 4000 miles. These are Michelin Diamaris. OPC quoted £300 per tyre. I have rung around and got that down to £240. What I was told by one of the tyre places is that everyone should have their tracking checked every three months! I certainly wasnt aware of this.

Different sized tyres will perform differently, but 996 owners have been know to go through Rossos in under 5k miles ! Same car, same driver got 14k miles out of Michelins. How much the tyres have in common is very debatable, but Rossos do seem very erratic in their wear rate.

er... what do you think causes the car to slow down and accelerate? The main friction point between car and outside world is the tread on your tyres! (Paul's will last much longer because he's at a much more constant speed on a motorway). (I completely accept that only 4000 odd miles is very low, but I don't think you can compare with motorway miles)

Tyre dealer also said Michelin's should last 20,000+!

Well Ive just swapped from Diamaris to Pirelli cos the wear was so bad I didnt think it could be worse! I only get 8-9K out of a set, tyre fitter says he's seen worse in a Cayenne. Wear is pretty even, front and rear. Regards Neil

ORIGINAL: NIL98 .... Wear is pretty even, front and rear....

That's good - they must have the power distribution about right. It always seems to me that there must be inefficiencies in the process if (on a 4 wheel drive vehicle) the tyres wear at different rates. But on my 993C4 the rears wear at least twice as fast as the fronts, and on my Toyota RAV4 the fronts wear nearly twice as fast as the rears...so neither have it right!

I run diamaris on 20" technos(Cayenne "S" 06MY) and the shoulders at the front always wear out V quick,they must take a beating with all that weight and grip,something has to give..!?

When I bought my KN 3.2 it cam with a new set of P Zeros on 19's, in reality they lasted no more than 9k and although the geo was spot on had uneven wear, pressures where as handbook. (steel sprung) Changed to 20's with Continentals have to say lasted much longer with even wear, still going strong at 15k. IMO P Zero are pants...had them on previous Impreza's & at the time promised my self never to use them again.....there are much better around and found that to be so. 2.5 ton on p zero.... they can't cope.!
