Noticed my crappy original Dunlop rear tire was a little deflated last couple days. I was losing 3 to 5 psi per day due to a tiny pinhole I found using the water-soap method. Found out Dunlop offers tire replacement if thread has not reached 50% wear but I'm thinking about dumping them for good. It seems the pinhole was caused by tire defect instead of any sort of piercing because it looks more like a tiny little crack rather than a hole. Those Dunlop sucks anyway. Any thoughts? Should I insist on Dunlops?
