Miles, you are one smart fella. I guess with me living here in Florida, I have the option to ride 6-7 days a week. I do not "store" it very long. I do ride, albeit not like some of you guys, but that's based on where I am at in my life. That said... I will be looking at my tires more closely and more seriously then before. I have both bikes in the garage and it not heated per se, but it gets quite warm to sizzling here.
So...for a rider that does not go through tires like yourself , once purchased and broken in, how long ( miles and or time stamp) should they be strongly considered time to change?
