I have choice, your word or Sheldon Brown's...guess who's I'm going to take?

^ +1 Micheline Pro Race 2's.

Just changed the originals (2005s) with new 2007 foldable PR2's, and man, were they tough to thread over the rim...

But they have a red sidewall and my bike's red so I'll go faster now!

I know there's a lot of debate over tire rotation - just my two cents - I always replace both at the same time on my road bike - these are the lighter softer rubber like Conti GPs or Force/Attack. I replace them as soon as they start to look questionable - major cuts, noticeable tread wear, etc. I spent a decent amount of money on this bike, and ride it for performance enjoyment, so it seems silly to try and milk mileage from the tires over $25-50/tire. We don't put in that many quality miles so One or two sets a year is the most I need to buy for this bike.

I do keep the older ones (Fronts, at least) and use them on my beater road bike, including use for the indoor trainer over the winter. This bike gets a variety of use, and I have used thorn proof tubes in the old tires (yes, I know they weigh a ton - but better that than flats).

On my mtb commuter, I use 1" slicks, and I rotate front to rear, tossing the old rear tire, moving semi-worn front to the back, and putting a new one on the front. This bike gets ridden 10-12 mph max (maybe 15-20 mph rolling down the bridge), and the tires have a hard life on rough streets. If I replaced them every time they got a cut I'd need new tires every week. I usually need a new front tire once a year or so.

As far as I know, there is no debate over tire rotation. No one does it, except for the Sheldon Brown method of putting new tires on front wheel and moving the old front tire to the back wheel. Moving the rear tire to the front is always a bad idea.

Umm.... what?

I always rotate my tires to extend life. All you have to do is switch them out at about half the life expectancy of the rear tire. This helps the tires wear evenly and you get a bit more life out of the set. Of course, I only change tires as a set anyways, so it makes sense for me.

Here's the average life of the two tires I've ridden:

Panaracer stradius pro: ~1500 miles
Kenda kriteriums: ~4000 miles

You need to read the threads on this here. I'm amazed at how many people flip rear to front, to get 'even wear' out of a set of tires. I knew from common sense not to do this way before reading Sheldon Brown's advice. I used to rotate the tires on my car back to front but only if the rears were in excellent shape. Even there, I typically purchased a new pair for the front if funds did not allow for four new tires. However, on an auto - especially front wheel drive models - the front tires typically wear faster.

1000 seems a TAD low, most general numbers I've seen on here put the lower end around 2000mi.

That being said, if they're not very good tires they are more likely to wear out faster. If you run gatorskins or armadillos you get a bit more durability out of them.

And you always put your better tire in front, and when your rear wears out, you switch your front to your rear and your new to your front.

just replaced my krylion carbons. 700x23. i rode them at max pressure. i weighed between 210 and 225 during their life span. 99%+ of the miles were on roads and paved paths. some roads were bumpy with lots of asphalt repairs to pot holes. however, i didn't ride over many unrepaired pot holes. overall, i'd say the roads were avg.

i got just under 4000 miles out of the rear tire. no flats (until the tire was done for). also, had one rather deep cut in the tire within the first 200 miles.




i'll stick with krylions. luckily, i bought a backup set when i got the cut on my originals. apparently they're not being made (for the time being).
