I was just curious to everyone's opinion on when to proactively change you're tires. I have a trek 7.3 fx that I bought in may of 2007. I would say it only has about 500 total miles on it. I have never had a flat but I do have an inner tube in my seat pack just in case. So the tires and inner tubes are over 5 years old. I know many people would say "you need to ride more if you're only averaging 100 miles a year and I agree. Hopefully I'll be riding a lot more this year. The tires look alright. Nowhere near new.
As you can see there is still some tread left
Just wondering what everyone thinks.
