I was given a new Dunlop sportmax 207 rr and i need to throw on a new set of tires. the problem is that i cant find the same rear tire anywhere! I was going to throw on either a Dunlop qualifier and a Michelin pilot power 2ct. I was wondering if it is okay to mix either of those tires with the 207. Also does anyone have any opinions on the Dunlop qualifier? Thanks guys
