|Poll: What tire do you use and how long does it last?||Fez|

|Seen the recent tire posts and notice that absent flats or deep cuts, some have said tire treads actually wore out as soon as 500 miles. What causes this kind of wear?
1. Lance-like power and torque causes rear tire wear?
2. High speeds combined with fast turns = huge cornering forces?
3. Tire manufactured with an extremely soft compound and a very thin layer of tread on the tire to save weight.
4. Clydedale rider weight (but according to recent poll, a lot of RBRs are lightweights).
For comparison, I have yet to come even close to completely wearing out a tire. My current tires have 3,000+ miles. Rear shows very light wear, front still looks like new. Michelin Axial Supercomp 700x23.
What are your experiences? Tire model and how many miles/years?

|As I posted earlier I've gone over 5000 miles on this pair of Conti GP's with life still left in them.The rear has started to wear a flat spot and has minor sidewall scuffing but no major problems.I'll get a new one in the spring and rotate the front to the rear next spring.I've had great luck with Conti's.Only 3 flats all year and one was due to a bad tube valve.|

|I replaced a front tire which showed a slight split developing on the radius of the tire. The split became more obvious when I took the tire off. Anyway, I thought that it would be better to be safe than sorry.|

|People using race tires for normal riding and heavier riders causing increased wear. Also riding on crappy roads or not watching what you are rolling over. I use Conti GPs and GP3000s, weigh 195, pump em to 120 and get about 2-3k out of a rear before it starts getting flats from being too thin. Never had a sidewall problem with them but you do get that thread unravelling which to me seems mostly cosmetic and not a real problem.|

|5. frame/fork misalignment.
Just like a car, if the front or back droputs were out of alignment by a few percent, wear would be increased as tire is "dragged" across the road sideways as the bike goes forward.
That said, this Clyde gets about 3-4000 out of a pair. I even got 5000+ out of a Michelin carbon comp before glass prematurely ended it's life. Might have got 6 or 7 out of it.

|SnowBlind's answer is so moranic that I have to respond. A bicycle does not "drag" the rear tire if it malaligned. The rider would simply ride with the front wheel turned ever so slightly (a fraction of a degree) to one side or the other. The rider would not even perceive a difference.|

|He can clarify his original point, but this is what I think he meant. He drew a comparison to the automobile. When you get your car aligned, they should check the toe setting. On the rear tires for ex, if the toe is in or out (not pointing straight ahead, i.e. / or \) the tires will literally scrub and wear faster since they are not pointing straight ahead.
I don't know if this condition on a rear bike tire can contribute to accelerated tire wear as dramatically as it could on a car, but I think that was what his point was. Maybe "drag" wasn't the best word choice.

|I used the word "dragged" (in qoutes) because I really could'nt think of a better way to explain it.
But the fact is if you are 1 % of alignment from dead center, then for every 100 meters you travel forward, the wheel also drifts one meter to the side. Because, as you said, the rider compensates by turning the wheel sightly to the other side, the back wheel does actually drift, it skid or "drags" back onto the centerline.
Motorcyclists (at least the one' I know) call this a "cast and camber" problem, and it greatly increases the wear on a motorcycle' rear tire. Because of the wider tire, you can sometimes see the cupping on one side of the tread.

|I think there are a bunch of maintenance hypochondriacs out there constantly changing tires and chains (I've read at some INSANELY brief intervals).
I have at least 3000 miles on a set of Michelin Race Pros- never had a flat (knock on wood). The rear has a bunch of small cuts in the tread... I have a new set of tires (same thing) lying around for the day I need to replace them.
I have been very annoyed at riding situations (we'll call them "near misses") where I've had to lock up the rear wheel (to lay the bike down after a run in with a car) , but that is as abusive as my riding seems to get. I keep my tires "properly" inflated all the time, and I think that helps prolong tire life.)

|Rider weight and tread thickness. Rear tires wear from the power transmission to the road, and a heavier rider is obviously putting much more power through that tire. Front tires, with only slightly less weight on them, essentially don't wear out (as measured by weight loss). They get old, cracked, crazed, and cut, but the rubber does not wear to any appreciable extent. My wife weighs 1/3 less than I do, and her tires last at least 2X longer. Comparing a Conti GP and a Conti GP 3000, the GP lasts roughly 2X longer than the GP 3000 because it has roughly 2X the tread thickness.|

|I generally ride Michelin Axial Pros and get about 1500-2000 miles on the rear, but the front never seems to wear out. For some reason, I get better mileage and flat resistance with the black APs compared to the green ones. I change my rear tire when I start getting more frequent flats, sidewall cuts, and/or the thread just starts wearing through. I don't like to press my luck and ride tires until they literally fall apart. It's no fun stopping to fix flats.|| |
