when to change tires?Gall
Sep 4, 2001 6:42 PM
hello again..

i run conti 3000 gp. i have my last race of the season coming up on saturday. my rear tire is squared off. there are some real minor nicks in it.

how can i tell if i need to change the tire. what signs should i look for to show that the tread is worn out.

this is the first pair of conti's that i think i wore out before the sidewalls went... i still cant believe i stuck with them... just couldnt find anything else i liked better...

thank you everyone for helping me with a great/fun season!


ps.. and thanks for putting up with my many many stuipd questions :-)

I have used Conti GP3000's exclusively for the past two seasons. Squaring off and minor nicks are normal. I have a pair of ugly yellow Conti's what wore so well I just got tired of looking at them and I pulled them off.

I look for large cuts and wear through the first tread layer. Or, if I have a doubt about the condition, I just pull it off so I don't have to worry about it, better safe than sorry....

Ya know, I have ridden my GP 3000s for at least 3000 miles and my rear one is very flat and has tons of nicks, but I have not ever had any problems with the sidewalls. I have had the cotton runner where the sidewall makes contact with the rim come unglued but no problems with the sidewalls. I have about 2000 miles of commuting on them too. Perhaps its because I have 700x25cs with the wider tire, perhaps? But I've heard all these people having problems with Conti sidewalls, I have never had them and my replacement rear tire (in the mail) is another 25c GP3000.

Maybe I'm just lucky!

No luck involved, IMHO. I just ordered a set of GP3K's, to replace a set of 2K's that still have alot of life in them @ 2200 miles. Excellent product.

I ran over some glass, which cut across the bias of the tire, but not all the way thru. I'm gotten more use out of them but I'm leary & will replace it for my Century on Saturday.

The guy at the lbs said side wall problems are typical for Conti GPs but then again he thought they only came in Grey?!
He was pitching an Alligator model with more rugged sidewalls. I actually picked up a pair but I haven't used them since I found more life in the cut tire.

I also read a few horror stories here where tires have been taken to the limit. I'd err on the side of caution, if you know where that's at.
