How long do lawn mower tires last? As Corcoran noted, you should reasonably expect to change a lawn mower tire every three to six years, but it really depends on how often you use the mower.

You have to perform routine maintenance on your riding mower to make sure its running at peak efficiency, but when was the last time you checked the tires?
