My Van had its first MOT today and failed!
The problem is the back tyres. With the weight of the machinery in the back the van obviously sits low. on the inner rear arches there is a seam which has been rubbing the tyres and hence have trashed a perfectly good pair of tyres since september. The tread is still excellent. £145 quid lighter and am back up and running, the tyre fitter beat the seam over for me to give the clearance required, wasn't rubbing all the time just when going round corners apparently.
So if you own a boxer with a tm it may pay to check this out!
mines a lwb 3.5 tonne 2.2 hdi by the way.
cheers Goron
