Just bought 190/55/17 Dunlop Sportmax Qualifier rear tire

My rear tire on my R1 seriously needs to be replaced. The center of the tire is superbald and you can see the metal wires. It also now start to drive funny, unreliable. Anyway, I had Shinkos on there 190/50/17 same size as stock, but there was a deal on Ebay for the 190/55/17 so I went for it. I first checked around if it's a good idea to go for a larger size tire, but everyone seems to be extremely happy with the choice. I hope I wont see less acceleration, but can definetely use more grip and cornering confidence.
