HI again Spud, Locally we have a Tyre check week where random checks are done on tyres by the police,who check ratings etc carefully.Tough if your Vanquish is on Colways. All very laudable, BUT light commercials should have C rated tyres. It is unclear what category a SC falls into. Is it a car or commercial. C rated tyres are designed mainly for loads & durability rather than wet grip. The 3lt turbo SC can be a bit tail happy in the wet on C rated tyres. Not a problem for an old rallyman like me but it scares the horses,and the boy police are not impressed when buspass holders leave a wet roundabout sideways on opposite lock with a broad grin.
