If you feel it shouldn't have failed, you can appeal to VOSA.

Don't the council do MOT
From the MOT Manual.
Method of inspection
1. Check all road wheels for
a. cracks, damage and distortion particularly the rim
b. presence and condition of spokes
c. security
d. stud hole(s) visibly badly worn
e. wheel stud(s), bolt(s) or nut(s) missing
f. heel stud(s), bolt(s) or nut(s) loose
Reasons for rejection
a. a wheel badly damaged, distorted or cracked, or with a badly distorted bead rim
b. a wheel which has a spoke(s) missing, cracked or excessively
. loose
. bent,or
. corroded
c. a wheel insecure
d. excessive elongation of a stud hole(s) in a wheel
e. a wheel stud(s), bolt(s) or nut(s) missing
f. a wheel stud(s), bolt(s) or nut(s) loose
Sounds like a legitimate reason for failure to me. "Excessive" is open to some level of interpretation by the individual tester of course. MOT testers are always schooled to "pass and advise" if there is any doubt, which would indicate to me that he thought the wheel rim was clearly excessively damaged.
If you feel this is unjust, you should take it up with VOSA via the appeal process.
Still yet to find a good garage.
Only today I got my car back after having sent it in to swap out my Alternator.
Not only did they break my power steering (!!!!!!!!!!!!!) but they also didn't rebuild the front end properly, left half the bolts missing and didn't put my engine cover back on.
FYI anyone in Bristol, DON'T use SFTebby and Sons
