Stretched tyres

I've just been looking at a BMW M3 with 225/35r19s fitted to 10.5j rims. It's not in for MOT but I got involved as an apprencite was about to mane an upcockage.

the car was in for a wheel balance. When he jacked it I saw both front wheels spin themselves and settle with an obvious heavy spot. He gunned the wheel bolts out and there was only two turns of thread in each bolt screwed into the hub. the 10mm spacer did not have a centreing boss. He balanced the wheels and said "they're both ok only Zero and 5 grams on each wheel"I looked close and said he shouldn't put the wheels back on, and the customer should be informed. I put a wheel in to check things out and they won't fir without spacers, and without a centre boss the wheels don't bolt up concentric with the spindle.

Next concern came from the under-sized tyre on the rim. he'd run over a hedgehog and about five spines had penetrated the sidewall causing punctures, this is the bit of sidewall that faces almost straight down towards the road. The sidewall is not reinforced to the same extent as the tread and is vulnerabe to punctures from hedgehogs and all the other debris laying on todays roads.

The point of this??? Dangerous with a capitol F! yes, MOT fail NO!

I might have failed it for wheel distorted as it runs miles out of true, a fertical variance of about 4mm seen when the wheel is spun but that would have been an error, The wheel wasn't distorted, it just looked it.
I couldn't fail the inadequate bolts because I wouldn't have seen them.
I couldn't fail the idiotic choice of tyres
I couldn't fail the punctured sidewall

We put the car outside on its spacesaver and a spacesaver we nicked out of a staff member's car and told the customer to put standard wheels back on, but we stood and watched him put it back just as it was. When his wheel falls off I hope he doesn't wipe out anybody I care about.
