alloy wheel nuts
Discussion
just been to have new front tyres fitted at the same place i had the last (used) ones fitted , 6 months ago, and they have broken 8 of the nuts trying to get them off, they put them on , there is still part of each nut still on so the wheels still won't come off.
the car is an 88 ,911 is this a common problem or bad workmanship on there behalf?
the lad who did the original job left last week, luckily for him.
any ideas how to get the last bit of nut off without damagind my wheels .

I had the same problem with the alloy locking nuts on my 1990 C4 after some idiot (ME!) over tightened them after having all of the wheels off to clean them.
I would put money on them having overtightened them with their mega-torque airtools.
The Porsche prescribed torque settings are surprisingly low, precisely because they are alloy nuts.
Good luck

Steve,
Go down to your nearest quality tool factors and buy a Starrett 19mm hole saw with a A1 arbor. Fit the arbor into a speed controlled electric drill and remove the centre edrill from the middle. Screw on the hole saw blade and then, using the stud as a centre guide, saw through the nut until you are a gnat's whisker away from the wheel. Use grease or WD40 as a lubricant. Once you have done all 5 you should, with a bit of leverage, be able to break away the remaining thin sections of nut. With the nut removed and wheel off carefully unscrew or pick off the remaining thread sections left on the studs.
If you are careful this process will not damage the wheel or the studs, although if you need to deburr the stud threads afterwards you will have to either buy a M14 x 1.5 die nut (expensive) or use a steel wheelnut as a cheaper alternative.
