Better check out the rear tire (usually the first to go).

Both I and my wife installed "Mr. Tuffy" on our bikes and after 
about a year, Mr. Tuffy sliced through the rear tires on each one.
The bicycle dealer I go to has had similar reports.  I have gone 
over to Kevlar belted tires with much better results.
