Tire rotation

What tire rotation plan do you use?
  1. When rear tire shows flatness, trash it and move front to rear and put new on front
  2. When rear shows wear, replace rear w/ new. Keep repeating until front shows wear eg after 2-3x replacing rear.

I use GP attacks, different front/rear tires, and they are directional.
You really should change both tires at once, the rubber gets harder with time and you will end up with uneven grip.

#2 personally. I believe Sheldon Brown has an opinion on this, I'll check his site.

Here it is:

Tire Rotation

by Sheldon "Put The Good One In Front" Brown
It is common for a front tire to outlast a rear tire by as much as three to one. Rear tires have more weight on them, and also have to deal with drive forces.
This disparity in tread life is exacerbated in the case cyclists who rely on their rear brake (you shouldn't! See my article on Braking and Turning.)

Well-meaning cyclists, even some mechanics who don't know any better, sometimes try to deal with this by swapping tires, putting the less worn front tire on the back wheel, and moving the worn-but-usable rear tire to the front. The idea is to equalize the wear on the two tires, but this is a serious mistake, don't do it!

The only time tire rotation is appropriate on a bicycle is when you are replacing the rear tire. If you feel like taking the trouble, and use the same type of tire front and rear, you should move the front tire to the rear wheel, and install the new tire in front.
The reason for this is that the front tire is much more critical for safety than the rear, so you should have the more reliable tire on the front.

If you have a blowout, if it is on the rear tire, you have a very good chance of bringing the bike to a controlled stop. If your front tire blows, you can lose steering control, and a crash is a real possibility.

Uneven grip yes... but Lance's mechanic only uses aged tubulars (10 years old for Lance, 4 for the other team... I think). The aging makes the tire more supple.

LOL!

Perhaps you should swap hubs but keep the tires on the same rims and rebuild the wheels at each switch. Not so tough on the forks, but there goes the time savings.

The "aged" tyres that Disco use have been in a dark cellar for 10 years, not out on the road in the weather.
