conti GP 3000: when to change?(7 posts)

conti GP 3000: when to change?Gall
May 27, 2002 7:47 AM
hello again,

i ve been using a pair of conti GP 3000. i have no idea how many miles are on this set.

the rear tire is squared off. i ve heard that the squared rear tire is very normal. SO.... how do i know its time to change it?

The rear tires on the GP3000's will square off after a couple hundred miles. Some guys rotate their tires once at this point. The squaring off is normal, I keep the tire until it starts to wear through the first tread layer or if it gets a very nasty cut. I don't rotate, I wait until the rear tire needs replacing then I move the front tire to the rear and place the new tire on the front rim. Of course the name of the game is to make a rear tire last it's whole tread life before you have to chuck it. If I have to replace a fairly new rear tire, I don't bother to rotate..

I went through 5 rear tires last year, the front is still in good shape..generally I don't bother rotating my tires, once I start seeing the threads from the tire casing in back I simply replace it with a new tire.

If you're leaving one tire on the front, it is aging, though not really wearing out much. IOW, it is oxidizing, cracking, crazing, hardening, getting nicked, etc. If you rotate the front to the rear when the rear wears out, you'll still have a decent tire on the back and a new tire on the front - the safest for traction. I get 2500 miles or so on a rear GP3000 (under my 180 lbs) before I start to see casing threads.

My rear Conti GP 3000 started flattening at 400 miles and were completely squared with major side cuts at 800. The front looked brand new. I ended up replacing the rear with a harder Armadillo Light which feels like it rolls faster. 800 miles came way too quickly for any performance gain I perceived I was getting with the Contis.
