Is it a big deal mismatching tires? Right now on my bike (a new to me Gixxer 750) I have a practically bald Michilan pilot sport, and a Bridgestone 056(good tread). I dont have the funds at the moment to buy tires but I do have a new BT014 sitting in my garage. Would it bad to run the BT014 in the front with the BT056 in the rear? Granted, in a month or so the rear would be replaced with a new 014.
