I wrote "Designer Tyre" meaning I don't see the point of paying £150+ per tyre because they have a well known name when I know that sooner or later the rotten roads will damage the tyre, so I'd prefer to pay £70 per tyre.

I've had people say to me "Oh but using tyres that aren't Michelin or similar will make you have an accident!" but I disagree, driving like a tool will make you have an accident.
