they start to square off? The rear tire looks as if it is developing a flat section along it' centerline. Axila Pros with about 1100 miles on them. The front has the same milage but shows no such wear. I assume their is more wear on the rear due to the weight distribution over the length of the frame. Does anyone rotate tires to get more even wear out of a set of tires?

I rotate my tires about every 500 miles, and just like a car they will last much longer than leaving them in place for many miles.
Hmm, I don't know about rotating.Parker

Its best to always have the best tire up front.
I'd never put a worn back tire up front where good traction
is most important. I think its better to buy one tire at a time,
always putting the new tire up front, the old front tire on the back.
I've found that you end up w/ the same overall tire life (looking at front and back together) but always have good meat in the turns.

I've read a few writeups about this from very knowledgeable and experienced sources, and these people say that rotating bike tires is a big no-no.

Sure, the "drive" wheel (rear) will wear more quickly than the front; makes good sense. Do you really want to risk putting a more-worn tire on the front (control and safety) part of your bike just to "save money"? By putting the weaker, much-more-worn-out rear tire where you need the utmost in dependability for steering, cornering traction, downhill grip, etc., you're risking flats and blowouts where you DON'T want to risk them. Say you're going down a hill (or turning a corner at speed) and your front tire either flats or blows out due to wear, tear, cuts, and thinning treads. NOW WHAT?! You lose control of the bike and risk getting seriously injured and damaging your precious machine--much more expensive than a $35 tire.

When the rear tire gets thin, do yourself a favor and replace it with a nice new one. Same goes with the front one. Check your treads frequently so you recognize when this time comes. With all the money we spend on cycling-related goodies, make TIRES a priority; they're what keep you rubber-side down and not skin-side down.

It's a bit different on cars, since there are four wheels touching the ground and your rear tires often get LESS wear (most vehicles have FRONT-wheel drive nowadays). The exact opposite is true for bicycles. My concerned advice: DON'T ROTATE BIKE TIRES AT ALL. Get new ones as necessary; they're not that expensive, and aren't worth the risk.

Safe rides,

Thanks. I understand the safety factor. I plan on installing new rubber, but I was wondering if I should have rotated them prior to the rear exhibiting more sever wear than the front. Do you feel that this is a worth while endeavor for the future?

Some people will tell you that you can get more mileage from the practice of rotating your tires. It isn't a good idea though, because you risk your safety for a very negligable increase in mileage. Your rear tire loses some material from the weight that it supports combined with being the tire that supplies the power. Your front tire doesn't lose material as fast. You want your better tire on front. Front blow-outs and flats can cause situations where you lose control of your bike. Think of what could happen if you lost control of your bike near fast traffic, or when traveling at speed. Scary, isn't it? Rear blow-outs and flats can usually be easily ridden to a safe stop. If you rotate a tire with less material on it to the front, then it is at greater risk for a flat or blow-out. You can see how this could be real trouble. You don't want to do anything that might increase your risk of a front tire failure that risks your personal well being. This is why rotating tires is a bad practice.
someone wanna buy me a new tire?girl

Heh heh, I'm so broke that my rear tire barely has any tread left on it at all...its going seriously bald. Boo hoo. Lucky, I haven't flatted in the last 4 months. I guess I'll just wait until it falls off my rim, or completly disintegrates. Then i'll just glue the tube to the rim and ride on that. (kidding of course...it's just that I'm a poor college student, and no, I don't have $35 for a tire...anyone wanna sponsor me?)
In the long run, rotation doesn't save moneyRetro

I do rotate, and it's never caused a problem (but I agree with the arguments against it, too...). Either way, though, if you use every tire until you think it's worn out, you're not going to save money by rotating. You move the spending around a little, but your wallet doesn't know if the tire's on the front or the back.

the rear out, move the existing front to the rear and put the new tire on the front. As it stands now, there appears to be a significant difference in the wear of the front and the rear - atributed to carrying most of the weight and sprints contribute to much of the wear. From everyone's comments, the existing front will make a better rear tire than front tire. It looks to have many more miles in it's future but not as a front tire.

THat is about the only safe way to rotate. Move the old front to the back, and put a new tire on the front. You'll get a little more mileage that way, even if it is just a little. That, and you don't risk putting an old worn tire on the front where it can put you in danger. That is the part of rotation that will get you.

Consider also the effect (admittedly small) the "squared-off" tire could have on handling when on the front.
When I buy a set of tires, I get three, one to use as the front and the others are for the back. That way I don't ride on miss-matched tires, and they all wear out at the same time.

safety wise i think you are fine and dont need to replace the tyre..someone probably already said it but get a new one for the front and put the front on the back..

I stopped rotating, it wasn't worth the hassle. I usually go through about two rear tires before I end up replacing both of them at the same time. I just replaced a set of Conti GP 3000's with the ugly yellow tire thread. These by far are the best wearing tires I have ever used. They are still good for another 1K or so, but I really got tired of looking at that grimy yellow color. It also gives thought about exotic colored tires. If your LBS doesn't carry that particular tire in stock, then you have to ride with two different colored tires, or purchase two new tires of the same color. God forbid anyone would want to screw up the color scheme of their bike.
Sheldon Brown discourages rotating tires, the reason behind it is that you want your best tire on front..
