Omega General Help / Have garages stooped so low?
« on: 28 October 2016, 07:04:05 »
hi all
about 4 weeks ago, i put my car in to a local garage, that prepared and took it to get MOT'd, they told me that it needed brakes and a new tyre.
all round i have 235 45R17 97W's, but just noticed tonight that their replacement, on the back axle, is 235 40R17 90, which from my freshly learnt tyre markings search, means a 20.8mm diameter difference!
A) Are my calculations right?
B) isn't this illegal?
C) Therefore should the car have passed the MOT?
D) Most importantly, having just driven to Liverpool and back, 350mile trip, cruising in the motorway fast lane, also country roads in the dark and the wet, how safe was i, and anyone near me?
i'm hoping that it's an apprentice screw up, not that a garage would knowingly do it just to get rid of old stock
any insight would be most welcome
