Advice on Tire
So I recently purchased a set of Continental GP 4000s (but was sent S II actually) for my new rims. Within 100 miles, the sidewall failed on the back tire on the same roads I had commuted on for 3 months with ancient gatorskins and bontragers that I had bought used at end of life...
I was riding at about 10 mph with only me (150 lbs) load at 90 psi rear tire. Didnt run over anything, hear a pop, hiss, and pull over to find a completely flat tire. Attached is a picture. Unsure if it was cut or simply exploded... it's not located anywhere near the contact with the ground, and it's deeper from the inside out.
Anyway, I was wondering where to proceed
a) shoe goo the tire back together
b) see if continental will replace on warranty (costs shipping)
c) new tire
As for the new tire, I wont be buying anything from continental on principle, so I was wondering what other options offer a decent blend of performance and durability for a bike that is primarily commuter but also used for weekend rides. Also, preferably on the cheaper end. Really got burnt here paying $40 for a tire that lasts a week and a half.
Thanks for your advice

From the outside, there are two areas that look torn. From the inside, it's all one long tear, with an island in the middle that is torn on the inner layers but not from the outside

I doubt it's a warranty. But sometimes companies will do a replacement for goodwill reasons. Good luck. Andy.

This screams glass cut, aka not a warranty.
Years ago, when I was in retail, this kind of bad luck was not treated as a warranty. But we tried to soften the pain with a very deep discount on the replacement. Our attitude was that we didn't want to profit on someone else's misfortune.

Thanks for the replies guys. What do you think about Vittoria Zaffiro II tires ($18 for wire bead) and Schwalbe Marathon GG RLX ($31 for wire bead)?

I can't speak for any particular tire except to say that tires are tires and luck is luck, and never the twain shall meet. (apologies to R. Kipling)

Any tire you can mention of will have users who love them and users who will loathe them. Tires that have nice, supple sidewalls will generally perform better in all ways except for sidewall cut resistance.

So just to add my anecdote, I ran Conti GP4000s tires for a season once, and I had four of them all die by sidewall cuts. I spent a lot of money on tires that season. Needless to say I tried other types of tires after that. I ride all the same roads every season, and I had never had a sidewall cut on other types of tires prior to or since that one season.
So according to my anecdotal evidence, Conti GP4000s tires have sidewalls that are easily cut. I believe they are intended to be more of a racing tire than a training or general purpose road tire, so they will have more supple sidewalls that roll easier but are more susceptible to cuts.
Don't give up on Continental tires, they make a good product, you just have to find the right tire for your application. Right now I have a Conti 4-season tire on the rear and it's holding up just fine. I think I have about 800 miles on it so far this season, and I'm looking forward to actually wearing it out by the end of the year as opposed to it suffering death by glass or gravel.
