I just bought purple color version of Yamaha Y16ZR V2. Im thinking of changing my front and rear tyres since stock tyre not that grip, especially during raining I can feels its slippering.I planned to purchase Corsa Sport Rain for both of my tyres. But the problem is can I use size 80/90/R17 (front) and 110/70/R17 or 130/70/R17 for (rear) tyres. inside manual its only recommended 120/70/R17.
