I've fitted HR rated tyres on g/f's MX5 when originals (and recommended by Mazda) were VR. Can anyone tell me if I've invalidated the insurance as the dealer suggested today? I mean, she never takes it above 80 anyway, so who needs VR tyres? Ta'

News Just In - Insurance company says 'no', policy is still valid, but just in case have typed up a letter confirming the telecon. with them.

Please, no more replies!!! :)
