MOT Failure - Opinions Please

cav551:
A quick look at Continental Tyres’ data gives some idea of the different load indices which apply to the single fitment of particular sizes of tyre which could be fitted to either of the front two (steering) axles.

(275/70 R22.5 index 148 150 151 or 152)
295/80 R22.5 index 152 or 154
305/70 R22.5 index 150 152 or 154
315/70 R22.5 index 152 154 or 156
315/80 R22.5 index 154 156 or 158

The load relating to the load index numbers has to be looked up either in the tyre manufacturer’s data when refers to one tyre or in the HGV tester’s manual when it refers to one axle.

As pointed out the actual plated weight of an axle varies according to manufacturer and to the vehicle specification ordered by the original purchaser. The plated weight can differ between axles one and two as can the actual size of tyre.

The information required for the vehicle to pass MOT is detailed on the VTG7.

So the OP should have had a tyre with, minimum, 154 rating for a single wheel as 154 corresponds to 3750kg ?

You would have thought ATS would have at least queried /advised him when fitting a 152 rating, 3550g on the opposite side ? It is stamped on them after all :unamused:
