it is that they don’t get the same life wear as a car tire. They are basically good for about 4-6000 miles, depending on the kinds of roads you drive and how you ride. Because DH uses it as a daily commuter, we are putting on about 2000 miles a month, minimum.
We bought it to save money on gas (which has absolutely happened) and time (also has happened) so it IS doing what it’s supposed to do. This is the primary reason maintenance is so high–it’s being ridden close to 100 miles a day. It just floored me to see what the “real” costs are.
