I am going to get a new Pirelli Sport Demon rear tire put on tommorrow morning. This will be my third rear tire in about 11.K Miles. Should I be getting better mileage from these tires? They are very soft and sticky and I am constantly leaning on my way back and forth to work. I mostly use the bike for my 4 day commute of 8 miles. And then lots of riding around town during the weekend. These tires are perfect for the EX500 since there are very few tires that fit our rims. Bias Ply instead of Radial though.
