Idiot question re 996TT front tyres

[cyrus1971]

Fitted new Pirelli P.Zero Assio' N3 all round. After 10,000 miles fronts are worn and rears are just 30 to 40% down Note this includes 2 track days and traction control on all the time. I like chucking it around corners but is this "normal" for fronts to wear out twice as fast as rears ? I thought it would be the other way around.

Certainly on my 993 C2 the fronts go about twice as quickly as the rears. I've always put it down to lots of low speed maneuvering in town

Hmmm. FYI - Not done many miles but they've all been quick (none in traffic - lots at very high speed) and had to replace backs - fronts still look like new (except the edges!).

(Edited to add.. Mich Pilot Sports N rated on a 996 tt X50)

I wear my tyres out in the ratio two rears to every front. Details mileages etc in my car running costs.

the rear tyres on my 996 tt x50 wear out around twice as quick as the fronts. the rears last around 7000 miles the fronts 14000

10,000!!! -you're not trying hard enough!!

Rears on my old C4 lasted about 3-5,000, fronts upto 10,000. Power steering and parking really mullers the fronts, try to turn wheel only whilst moving, it DOES make a difference on tyre wear.

Possibly right about that only really feel I have fully learnt the cars limits in the last few 1000 miles. Though I am fairly heavy footed. Maybe it is a Tiptronic thing ? Certainly you all seem to be experiencing the opposite of me wear wise.

[Melv]

Cyrus -just a thought. When did you last have full four wheel alignment done?

These cars are known to understeer anyway...

Going back to the power steering thing, turning the wheels whilst stationary really takes it out on the front tyres. Found this out first Audi A4 Avant I had, delighted in parking by palming the steering wheel because it was so light -soon wore out the front tyres.....

Perhaps that is simply the prob???

I've got..........
10k out of rears
15k out of fronts (& this with only the insides worn flat, would have been good for 20k without.

Don't forget to get a price from Micheldever when you do change, save you a packet!!!

It's worth checking the alignment as poor alignment eats tyres.
FWIW my roads tyres wear slightly faster on the rear but I usually replace all 4 as its marginal and on track the fronts wear slightly faster than the rears.

Make sure your centre diff is in the right way round?

[toby tucker]

17k out of fronts & rears - all were still legal (2mm + ) but rears were starting to go on inner edges

replaced all 4 last Friday with Pirelli Pzero Assims N3's from Micheldever at £626 inc 4 wheel alignment check & adjust

26k and counting on Mr 006 snr's boxster. But i suppose they biodegrade faster then they'll wear with some people's driving.

[cyrus1971]

Thanks all for the advice. 4 wheel alignment done about 1000 miles ago and Charles Ivey did have to make some big corrections. So most of the wear could well have happened before this event. Parking wise I am a fan of keeping it moving so less likely as the culprit. Will slew round the mean streets of SW London a little slower in the future.

The two things that will generally cause high front tyre wear are heavy braking (the front tyres do 70% of the work) or heavy turn in / understeer. Your car is engineered to have plenty of understeer as it`s nice and safe, you turn the wheel, you feel the front wheels struggling for grip and the car drifts a bit wide, nice and safe. This is particularly the case on slow-ish corners.

High speed cornering will tend to wear the rear tyres more. You lean the car into the corner and drive through the bend keeping more weight on the back of the car, thus the outer rear tyre does most of the work.

With cars wear differs hugely between different driving styles.
