Rule of thumb for tire changing?(8 posts)

Rule of thumb for tire changing?empacher6seat
May 24, 2002 8:42 AM
I was riding my bike the other day when it occured to me that I have no idea how old my tires are, how many miles are on them or anything (I bought it used). Is there a rule of thumb I can use for deciding when they should be replaced?

I have a freind who has used the same set of tires for 5 years now. The rear was showing threads before he finally replaced it. I guess if you aren't getting flats on a regular basis and you still see plenty of tread then don't worry.

Just because something might come up tomorrow that will make it impossible to get out on the bike. Not usually long rides though, those are only a couple times a week.

Why not bite the bullet and spend a couple of bucks on a new set? Maybe you don't "need" them, but the new feel, the knowing what you're working with etc. will make it $ well spent, IMHO.

When the rear gets visibly "squared" off, I say its time to change the tires...
watch for cracks, too...cory

I rarely wear out the tread on tires, maybe because I use 700x32s and 35s. Long before the rubber's gone, I start to see cracks and checks in the sidewalls (could be the desert sun, I guess). Little microcracks don't scare me, but when chunks of rubber start coming loose...
Squared off is pretty subjectiveKerry

I know people who think the tire is "squared off" at 500 miles, while the tires will last 3000. My experience has been no increase in flat frequency as the tire wears, and I wear them until casing threads just start to show. Then I move the front to the back, and put a new one on the front. I wear out tires fast enough that age is not a problem (crumbly rubber, crazing, cracking). If your tires are old enough to show serious age issues, then it becomes even more subjective as to when to change them.

I usually start getting flats when the rear tire gets squared off. Also, the bike seems to flop a bit when cornering. For that reason, I never put a squared off tire in the front, but just replace it. One front tire lasts about the same as two rears, unless it's got cracks and cuts in it.
