I've had a small stretch on tyres before, in my vw days it was 235/35/19 on a 10x19 and it wasn't too bad, just was worrying as I didn't want to damage the rim but those was the biggest tyres I could fit and get easy access to.
now this shit is awful and dangerous, having an inch or two contact with the road is just not right, I wonder if any of these idiots have had accidents and been taken to court?
