I ride strictly on the road for commuting and both my old Vstrom and my DRZ400SM always flatspot the rear tires after 6,000-7,000 miles, fronts always get 13k or so. I'm very conscientious about maintaining tire pressure, and going above or below the factory specs for tire pressure, makes no difference. Plus the rear tires are twice as wide as the fronts so you would think they would at least wear out more evenly. It seems such a waste because the sides of the tires still have almost all the rubber left on them. Can anyone recommend a good tire designed to hold up better on the highway? Please, no comments on riding harder or being more aggressive these are commuter bikes ridden on straight highways Ron W.
