Tire rotation (newbie question)(26 posts)

Tire rotation (newbie question)Tim.
Nov 19, 2001 8:37 AM
Should your tires be rotated every so often like a car. My rear tire is showing a lot more wear than the front one. Is it okay to switch these?

Don't rotate! Always keep your best tire on the front. For example when the rear wears out move the front to the rear and put the new tire on the front. Good Luck!
never go back to front.vanzutas

Your rear tire will wear more than the front. This is because the power is transmited through the rear and more than half of your weight is distribeted to the back. the rear tire will develop a flat spot in the center. If this tire is put on the front the front end will wobble uncontrollably at speed. which is not fun.

If they don't rotate,loosen the brakes...mr_spin

If you want to increase your chance of death or injury, put the tire with the most wear on the front.

In case my sarcasm hasn't come through, do not rotate your tires. Your front tire takes the most braking power, so you want it to have the most rubber. A good suggestion is to take the front off, put it on the back, then put a NEW tire on front. Throw the old back away.

That's not a rotate, that's a shift for those computer folk out there who know assembly language. The new tire would be the carry. Oh god, just ignore me at this point....
use old tiresDog

"Throw the old back away." Alternatively, get a set of cheap wheels (at least a rear) and use old tires on the trainer until they are totally gone. No need to wear out good ones.

Ever get a flat on a trainer?mr_spin

Until they are totally gone? I'm just imagining how silly I would feel if I got a flat on my trainer! I guess as far as flats go, that's the most convenient kind.

never did; when the threads show, then replace them; other than wearing all the way through, how else can you get a flat on a trainer?

Yeah, had to walk home! ;-) (nm)grzy

A front flat is usually more dangerous than a rear flat.MB1

A rider is more likely to lose control of the bike with a front flat than a rear flat. Therefore if given a choice some prefer to have the tire with less wear on the front wheel.

Some put a new tire on the front when the rear tire is worn beyond use and move the old front tire to the rear. This works assuming matching front and rear tires. Others use a wider tire on the front for comfort and control and a skinner, higher pressure tire on the rear. If either tire wears out just replace it. Some of this stuff can get too involved-ride your bike.

You don't mind, it don't matter.

Actually, you can rotate tires and many of us do. The one thing you don't want to do is try to strech the life of a shot tire. Blowouts on the front are always exciting during a high speed descent - maybe a little too exciting. By rotating your tires you can get them to wear out evenly - that way when you replace tires you can get that matched set of pink sidewalls on special. If you don't rotate then the back tire gets the characterisitic flat section down the middle, and you throw the tire out with out using the rubber off to the sides, so it's a little bit wasteful.

Been riding long enough to have done it both ways, but prefer getting the most out of the tires via rotating. Ultimately it's a matter of personal preference and philosophy. Also, If changing tires is a hassle for you then just skip it.

FWIW, I've rotated tires as long as I've been riding (coming up on 35 years) and it's never caused me a bit of trouble. But I don't try to stretch a tire's life at all--I usually buy new ones for fun well before they're worn out. If I HAD to run one with the fabric showing, I'd put it on the back for the reasons mentioned.
Don't forget, though, that in clean, dry conditions, a bald (smooth) tire will have MORE traction than one with tread: It has more rubber on the road. That's why race cars use slicks. Now if only conditions were always clean and dry...

This is one of those esoteric issues that cyclists love to debate, but probably doesn't make much difference.

BTW, older tires can get harder, making them have less traction, even though smooth.

But..grzy
Nov 19, 2001 3:25 PM
Wouldn't a harder tire have less rolling resistance, and therefore be faster?! ;-)

Yup - you don't mind, it don't matter.
to a pointDog
Nov 19, 2001 3:48 PM
At some point, harder is not faster. If you start bouncing over the road imperfections, even on a micro level, you lose time. Cornering and braking time might be lengthened, too.

OTOH, older tires, having lost rubber, could be lighter! Then again, if they are oxidized, that could add weight. Hmm.

In days gone bye, the classics riders wouldn't dream of using a tubby on the pave unless it had spent a few years hanging in a dark room. They never used new rubber because of a belief it punctured too easily on the cobbles. de Vlaeminck rode in 11 Paris-Roubaix races without flatting. He left his hanging in his attic.
aging tiresDog
Nov 20, 2001 7:14 AM
Yup, I have a few hanging in the garage, too. Not intentionally to age, just for spares.

Seems like the manufacturers could make them "aged," simply by using harder rubber compounds. Tufo's come pretty close.

Slick's better in dirty wet conditions as well,(as long as you're driving a bicycle not a car) though the difference is only academic as Doug noted.
The general tone of responses in this thread seems to agree on the presumption that a worn tyre is more likely to puncture than a new one... I've never found this in use and I don't see any theoretical reason for it either. If I was a piece of glass about to cut a tyre badly enough to allow the inner tube to escape and explode, or even just to cause a regular puncture, I wouldn't be at all fazed by another mm or two of soft squished rubber. I say, rotate or not at will, but check those sidewalls if you're worried about casing failures.
