Varies SO much, driving style, how good the tyre is & is looked after. I've got over 25,000 on some (Michelin), but less than 10,000 on others. So I've been told, hard tyres give better wear but you lose on grip & handling. I would expect an absolute minimum of 10,000 miles - that is less than the average annual mileage & I for one don't wanna be changing tyres every year !
