996 rear tyre wear?

[PT]

I have an '01 996 convertible and had the wheels and tyres changd when I bought the car a few months ago. Today I have noticed the on both rear tyres the inside edge is down to the wire whilst the remaining 85% of the tyres are not even down to the wear limits. They are 18" continental sport contacts and have done around 6,000 seldom thrashed miles. Surely this isn't normal, is it?

Uneven tread pattern means your wheels are out of whack. Getting them aligned should sort it out.

Camber out of alignement is prob' the reason.....

Under-inflation

Under-inflation has caused this tyre to wear on the outer edges of the tread, leaving the central tread area far less worn.

Over-inflation

Over-inflation has resulted in the central tread area being forced into contact with the road causing rapid centre and worn shoulders.

Mis-alignment

A typical example of the wear pattern caused by front wheel mis-alignment. (Toe-in or toe-out) The edge of the tread is "feathered" and worn progressively from one side. The wear ridges can be felt by drawing a hand across the tread.

Camber wear

Excessive wheel camber has caused sloping wear on the outer edge of the tread on one shoulder of this tyre.

Illegal/dangerous wear

This tyre has been used well after reaching the legal minimum pattern depth of 1.6mm.

End of life

This tyre has reached the legal minimum pattern depth of 1.6mm.

Emergency braking

An emergency braking manoeuvre with this tyre has caused the tyre to rapidly wear through the complete casing causing the tyre to deflate.

Cuts

Sharp objects can cause considerable damage rendering a tyre unserviceable.

Impact damage

This is damage caused by an impact to the sidewall. The bulge or "egg" indicates localised casing damage.

Yesp, sounds like a set-up/alignment check is urgently needed...

Thanks for that. I will book it in for a check, not at OPC of course as they want 4 hours labour!

an OPC will only charge 2.5hrs labour

My OPC quotes 4 hours and even then I wouldn't trust them to do the job properly.
