when i had a wheel bolt stuck in (after some twit tried to nik my wheel and reked the thread on a locking wheel nut), tried everything to get it out, the removal tool which just slipped off until it couldnt grip anymore. numerous chisels and hammers trying to make a slot to get a screwdriver in a windy gun on it, in the end most of the head just snaped off, so we undid 4 bolts a little, not the whole way just enough to put pressure on the stuck bolt but to stop the wheel falling off when the bolt snaped, then took the car into the car park of the garage, and drove around for about ten -15 mins, nothing, then put the car on full lock (so max pressure was on the bolt) and drove around in cirlces for about a min or so untill the bolt snaped and then removed by drilling into it and forcing an allenkey type tool into it and puting in on the windy gun so wheel bolts can put up with quite a bit, mine had 15+ mins of driving by just being held on by one bolt.
also my mate had wheels with a bolt pattern simelar, he ran them for about a year compleatly fine, i however wouldnt like to run them and would prefer something with the multifitment stud pattern more centralised.
