Time for tires

I had a feeling that my front tire was a little worn. At 11,000 miles I noticed a slice on the side of the rear tire and changed both tires. At 24,500 miles the servicewoman at the shop said that I needed the front tire replaced. When I came in to pick up the bike from the service (they had to order the tire which will be in later) I asked the mechanic how was the rear tire. His response, it's past 50% worn. That was all I needed to hear, so I had them order tires for both front and rear. There is too much riding on those two wheels to risk it.
