re: MOT.
"PROTRUDING WHEELS
I have recently purchased a set of alloy wheels from [a retailer] for my Ford Focus ST170 [who in turn fitted them to my car].
They appeared to be look a wider fitment than the original standard wheel even though they were the same size, 215/45/17, and were visibly protruding beyond the wheel arch on the front by approximately 5-6mm. They have also been catching the wheel arches on the front when going over speed ramps or bigger bumps in the road.
A local MOT Testing Station could not clarify whether this protrusion was classed as illegal so I would hope you could provide clarification? Steven Jewitt
As I understand the situation the only way the MOT is affected is if your new wheels actually foul the bodywork or any other part of the vehicle when the wheels are turned lock to lock when the vehicle is sitting in its normal position."
