I'll always use locking wheel bolts. I dont scrimp when it comes to tyres, and whilst the wheels aren't worth a great deal, the tyres are worth more than the car.
Simple solution to this problem is to NOT ALLOW tyre places to get their grubby hand on the Locking wheel bolts. Just ask them for their torque wrench and remove/replace them yourself.
The amount of times I've bollocked some scrote for smashing the wheelbolts in with an AirGun (not even winding the first couple of threads with the socket).
Consider it a lesson learned, and do the important bit yourself.
drb..... These thieves dont sh1t on their own doorstep.... they move into the nicer areas of town. Probably because the better areas have better wheels to pilfer.
Even torqued correctly (yes, some tyre places do!), the Vauxhall locking nuts are so poor, they regularly fail. There must be a better pattern part out there...
Last time locking nuts came of mine was at WIM, and they did torque them correctly (no guns used)
That was back in May/June time, so not that long. Going to try a few things to loosen them off.
- Using the old key, bash the hell out of the nut hoping to break / loosen the seal.
- Loosen all other bolts, roll forward, and stamp on the front brakes
- Soak in WD40 for a few days first before trying above
