V70 Wheels/Tyres: "security" wheel nuts

First thing I do with every car I own is throw the locking wheelnuts/bolts away and fit standard ones!

In fact, I suspect that airguns are only a problem when they're not pressed hard against the wheelnut.
Most tyre fitters merely hold the gun in place.

Remove them before you get to the tyre-shop and critically, put them back on YOURSELF.

Not True - I've had my V70 from new, I remove the wheels twice a year to clean the arches, and torque the lockers up by hand to 'only' 100Nm.

One McGard locker shattered, but there is an easy fix - see here http://www.volvoforums.org.uk/showthread.php?t=115289 Post #2

Yes, but how do you create enough inward pressure on the nut with a torque wrench, to ensure it doesn't slip ?

The only thing I'd ever risk using would be a crucifix wheelbrace - which allows the balanced application of inward pressure and torque.

The McGard key didn't slip, the bolt head shattered.

At 50 lb/ft. it is easily done with right hand on the head of the torque wrench, pushing inward, and the left hand on the business end of the wrench.

Slightly sideways on this topic. A couple of times I have been confounded by McGard bolts - the inevitable reason being a worn or lost interlocking socket. The solution is very easy. Photograph the offending bolt in-situ, email to McGard in Germany, and they will - for the princely sum of about 15 Euros send a new 'key' socket by return. If, as I did, you find the original bolt packing (after I had bought a new one - and worse still, finding another good one in the spare wheel well!) with verification number, McGard will apparently honour their lifetime guarantee and send you one gratis.

For myself, I am sorely tempted to dispense with the b*ggers - as they are generally a complete nuisance.
