Tread separation - not Firestone either!(6 posts)

Tread separation - not Firestone either!Lardog
Jul 5, 2001 2:58 PM
I did a clean up job on my rig yesterday and found, upon close inspection, what appears to be an area of tread separation on my front tire. The tires are Conti GP 3000 700x23 with about 250 miles on them. Upon checking it out, the problem does not appear to be ride related or from hitting something. Does anyone have a similar experience? I'm going to keep a close eye or perhaps just change it this weekend. I really haven't had good luck with these tires. Last season I put a pair of brand new 3000 on the rig and hit something wrong and blew out a sidewall with under 50 miles on the tire. Any suggestions on what to replace it with if I do? Vittoria? Thanks

what you mean by tread separation. I've ridden many miles on GP3000s, as have several riding partners, and none have experienced shortened life due to tread separation. When the tire reaches its wear limit (casing starting to show through the tread) there is a little bit of delamination taking place, but that it at the end of its useful life. Have seen this problem more in Michelins. Please describe your problem in more detail.

I have ridden both conti 3000 and axial pros and have not seen it happen. I did have it happen with vittoria techno twins The tread separated on one of the tires after about 100 miles LBS replaced it and the same thing happened to the rear. I decided not to chance it so I went back to Mich. axial pros.

If you bought them from a decent shop they should replace the tire. I personally prefer mich axial pros but to be quite honest when you are in that price range tires from michelin, hutchison, and Conti. are all pretty much the same. They are all good tires.

I had the same happen to me. The front tire top layer started to split. I had a few more miles om them. It look almost as it was dry rot. The back was fine. I had them around 3 months when I notice the tire. I went with michelin hi-lite prestige from perfomance. 3 tires for less than $60.00. I have over 2500 miles on them now and no flats.
Looks like I can get 1000 more out of them.

I never had tread separation, but I did have the same sidewall blow out with only a handful of miles on a Conti 3000. Like the previous reader I went with the Michelin Prestige and was very happy with them. I bought a new bike this season that came with Michelin Axial Pros and have gotten great service out of them as well. From now on I'm sticking with Michelin's.

Thanks for your help guys. I was really surprised when I looked at it. Going to keep a serious eye on it to see if it's a manufacturer flaw that's relatively harmless (not in fact separation) but just a sort of bad edge to the tread. Put 30 mi. this mornin' and will check it out tonight.
