With regards to tire wear, here is what Dunlop has to say: In answering this question, we must first make sure that we are comparing apples to apples. When you think of it, the vast majority of motorcycles are high performance vehicles compared to most cars. Consider that you rarely see a motorcycle with less than ''H'' speed-rated tires. By comparison, the vast majority of cars ride on tires with lower speed ratings. Power-to-weight ratio and speed are big factors in respect to tire wear. Unfortunately, when many people compare mileage, they do so with a family sedan and a much higher performance motorcycle. Another significant factor in this comparison is the size of the tire contact footprint. In the case of a car, the footprint is much larger and there are four, not two tires contacting the pavement. You must keep in mind that virtually the entire width of the relatively flat tread of a car is in contact with the road all of the time. A car remains upright, even when cornering. This results in a much smaller contact footprint for a motorcycle tire. High power-to-weight ratio, speed, size of footprint and other aspects explain why motorcycle tires wear out quicker than car tires. To obtain the best mileage from your motorcycle tires, observe the following guidelines: obey the speed limit; avoid quick acceleration and hard braking; maintain recommended tire pressures; and do not overload your bike or tow a trailer.
With regard to tire replacement: Always make sure that the tires recommended for your bike appear in a written form. In other words, don't follow someone's personal recommendation. It is too critical a situation, and one rider's preference does not necessarily suit another's. Take the advice of the professionals: the motorcycle or tire manufacturer.
With regards to a wider tire: This is possible in some cases, but again, it should only be done with the approval of the motorcycle or tire manufacturer. When considering wider tires, you must factor in clearance for width and diameter, the effect on stability and handling, along with whether your rim is wide enough. If wider tires are approved for a motorcycle, it is usually permissible to increase by only one size designation. When fitting a larger tire, always allow for some tire growth from the new to used situation. All tires increase in size after they have been inflated and are run for a few hundred miles.
Just some thoughts to consider.....ride on and ride safe.
