I recently got a set of new tyres fitted, Metzeler Sportec M1´s. The front profile should be 65 series, the shop fitted a 60 profile tyre. They didn´t have a 65 in stock. I was told this will be OK & that it should handle better. It´s taking a bit of getting used to, it does turn in quicker. My previous tyres were Bridgestone BT 010s which i liked. A mate recommended the Metzeler´s. Can anyone advise me on running a 60 profile on the front. Does it have to be a 65 profile? Cheers...
