Hi. My work colleague had continental contact 6 fitted all round when he bought his Fk8. All the tyres are the same and had a slight lip so help protect his rims. 6k ago he changed the fronts for the same tyres and although all the markings etc in the tyres are the same that lip is no longer there. He needs another set of 4 now but wants something that will come out a little to save his rims. Anyone have any advice with this. Thanks
