From: Dave Plowman (News) on
Mate had a puncture - a screw in the tyre of his new Audi A3. It's done
less than 1000 miles. Asked for some help since he's got a problem in one
hand.

Went round and took off the wheel - it's got a space saver spare so
decided to get it fixed there and then so just left it jacked up. The
screw was in the outer main groove of the tread - quite a way in from the
edge so thought it would be repairable.

Took it to Kwik-Fit - they are the nearest tyre place. Bloke got out a
special ruler and then a some sort of round template and pronounced the
tyre scrap. Quoted 160 quid for a new one...

Went to a specialist place I'd used for tracking - they have a four wheel
computer alignment setup - and they fixed it for 7.50.

What is the formula for how close to the edge of the tread it can be? And
is it somewhat of a guess?

BTW, congrats to Audi for giving the wheel bolt torque in the driver's
handbook. 120 Nm If only they took their own advice - it was nowhere that
tight when I took it off.

No, it's covered by BS AU 159f.

This may help:

The problem is with the dealer; it should have been checked as part of
the PDI.

Was it rechecked after 60 miles from its last removal?

I'm not prejudiced. I hate everybody equally.

They can settle in a little, especially so on a new car. The advice is
to recheck them after a period.

By what process would a wheel bolt, tightened to the correct torque,
become significantly less tight?
