Last week I went to go for a spin. Got all geared up, then as I did my walk around I discovered a nail in the rear tire. Boy was I upset. it's only got 7300 miles on it. Put a plug and can of puncture seal in it. Still holding air today, but dont want to risk it. Stealer only 200mm tire gonna cost $500 to replace. Not a happy guy today. Can I put a different brand on? I have Dunlops on now. Just put front on in June. Don't really want to change front again.
