Rotate tires or replace the rear with new???(14 posts)

Rotate tires or replace the rear with new???bc165

I've got about 800 miles on my Conti GP 3000s and the rear is clearly flattening. Do you guys rotate your tires at this point? It doesn't look too appealing putting a slightly flattened tire on the front, especially with the wet winter roads. What about letting the rear flatten out a bit more and replacing it around 1000-1200 miles?
Thanks in advance...
Front to back, new on front. NEVER old back to front. EVER. nmBowWow

Agree this is the best and most cost effective method. nmLive Steam

I regularly get 2500-3000 miles from a rear GP3000. I usually buys tires in groups of threes or fours. Two or three for the rear and one for the front. Never rotate.
This is great advice...morebicyclerepairman

Myself, I'm kind of anal (sorry, Doug!) regarding tires...its very important to me that front and rear tire match. When the rear wears out, I've replaced both. Yes, its more expensive, but justified based on all the money saved quitting cigarettes. I should have been using C-40's approach all along.
can't you.....divve

....replace the rear with the same type of tire? Normally it should match the front. BTW, I'm sorta anal about a whole stash of not worn out Pro Race tires from when I got bored with the color:)
C-40, how much do you weigh?Ian

I have never heard of anyone getting that kind of mileage out of a GP-3000 before.

I guess it depends on weight and tire pressuresnazgul

I weigh about 150 and get 2000-2500 out of a rear GP3000. I usually run them at 110-120 psi.
135 or less...(nm)C-40

At 180 lbs. I get around 2K miles from a GP3000 on the rear - this represents about a 10% weight loss. At 125, my wife gets 2X that. Tires wear due to power dissapation, whether from pedaling (rear) or heavy braking (front). In most cases, the front tire will not wear (lose weight) at all compared to the rear. If I left a front tire on while wearing out 3 rears, it would be heavily "aged" with cracks and crazing. Best policy is to move the front to the back and put new rubber on the front.

Rotate tires every 1,500 miles. I have an original set of Michelin Axle Pros on a Y-Foil with over 5,000 miles on them. I have only 1,850 miles on a set of Conti. Supersonics on a Gisallo, but had to replace them. Also rotated them.

...wear out two rears to 1 front. Then if the front has any meat left on it, change it to the rear and put new up front again.
Use the worn rear tire on your trainer/rollers (nm)innergel

The answer to your question is "yes." Depending on how flat across the top your tire is, you can run it on the front for a whole while you're wearing out your new rear.

The "new tires in the front" guys are basing their argument on the fact that if you flat the front, all heck breaks loose. Nice theory, but when's the last time you flatted a front tire?

More often than not, I've flatted a rear tire. It bears 50-60% of your weight (or more...) so things have a tendency to get embedded more often. Personally, I'd rather have the most rubber where my weight is.

My recommendation (after having a very flat Conti on the front end of my bike for a while) is that you should try out the flat tire in the front. If it affects handling, then you should probably replace it too. I know mine made the handling slightly funky when I wasn't going straight ahead... I could deal with it, but some other guys can't.

So, that help?
