I'm just curious:

• How many miles (km) do you have on your present wheels?
• What type of brakes?
• Why do they require replacement?
• Do you use both front and rear brakes equally (rim brakes), or do you favor one over the other?

My wife's present touring bike 's wheels have 29,000 miles (46,670 km) on them, and still have a lot of miles left in them. However, her older touring bike required a new rear wheel do to rim cracks developing around some spoke holes. She rode into a dangerous storm grate, and it hit hard enough to blow out both tires. This may have caused the damage to a wheel with less than 10,000 miles on it.
