Newbie question about cut tire...

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Newbie question about cut tire...

Hello, I have recently taken up road cycling and I have a question about cuts/slices in tires, specifically GP 4000. I have a new (under 300 miles) set of Conti GP 4000 (700X25) and noticed this cut today. Is this bad enough to replace the tire, or am I OK since it didn't puncture the casing?

I live in the mid-west so goat-heads are always a problem, but I think this was from glass/metal shards. Is this a common problem with road cycling? Thanks!

I've got tons of those. Apparently if the underlying belt is not exposed, you're OK. I DO check for small stones stuck in the rubber that might work their way in to the tube and cause a puncture.

There are shoe repair compounds like Shoe Goo for filling in larger cracks. Filling larger cracks keeps stuff from getting into the crack and causing more damage. I just buy several budget tires at a time and ride them until they fail or the carcass shows.
