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

Is my tire toast ?

I put a new pair of Pro4 Service Course on my bike, first ride and had a chunk of glass cut completely through the tire right to the tube. Cut looked pretty similar to yours...put some material in there and a new tube to limp home 6 miles. Gap in the tire was almost entire left-to-right width of the contact area.

After 2000+ miles on a set of Vittoria's which seemed to chuck everything away that I encountered on the road, and to have that happen on my first ride with tires 2x the price, just felt "painful." Left the Pro4 on the front and picked up some Lithion 2's cheap ($17/ea) for the rear that appear a little thicker in the contact area and ride pretty nice too.

I'm not saying that PRO4s are durable tires, but no racing clincher is. Lithion2s are more durable, but they ride like rocks.

Right. OP, you can get racing tires like 4000S and Pro4 that are sticky, supple and fast because the compound is soft. Or you can get durable tires like Gatorskins which are great to avoiding flats but are sluggish and are for a completely different purpose, or something in between like Lithions and as already said ride like bricks

I'm pretty sure the probability of a tire suffering a fatal cut is directly proportional to the cost of the tire and inversely proportional to the number of miles the tire has been ridden.

I only seem to get new tires cut.

Fold up a $100 bill and super glue it on the inside of that cut

Stan, the GPs are not indestructable for sure, but they are far more durable than the same weight Michelins. If you want to ride a 200-210 g tire and not have frequent cut failures, the GP 4000 is your best bet.

Robert,

No need to sell me. That's all I've ridden for the past four years except for one set of Pro's to try them

The last Michelin tire I felt very comfortable with, wear and quality of ride wise, was the Krylion Carbons. My Pro Race 2 cut like crazy. Never ever had a single cut on Krylion Carbons.

PRO Race 2s + 3s were nice riding race tires but they were far from durable. PRO Race 4 Service Course tires are more cut resistant, but still not very durable. PRO Race 4 Endurance is the replacement for the Krylion Carbon, and it sure feels like the same exact tire to me.

Wow, where did you find them so cheap? I'm riding some now and I'm just glad to have a tire that's fairly light, handle well enough for my riding (not like rocks as BoSox said, I've definitely ridden rocks before) and have yet to give me one flat or issue after several months. I almost feel like you can't put a price on such a reliable tire that doesn't weigh like 400g or some absurdity. Knowing I can go out whenever and not even have the thought of a flat tube go through my mind on a 250g-ish tire is a luxury. They may not be race tires but I'm not trying to race into work or while out doing training loops.

I had a Krylion cut pretty similar to the OPs tire. And like his, with barely 200 miles on it. I don't blame the tire. With rubber and thread versus glass and rocks sometimes you are just going to loose.

There must be reasons why some tires are more susceptible than others, or at least appear to be so.

Of course some tires are going to be stronger than others. But I'm just not going to chuck a whole tire model or brand because of a single prematurely damaged tire. Even the beefier road tires are still only a few mm of rubber and cloth. Hitting the wrong thing at the right angle is gonna do damage.

I've had exactly one ruined Mich and one Conti from these kinds of incidents with tens of thousands of miles ridden on 200 - 250 gram tires. I'm ok with that. I also ride Vittoria and Panaracer with no such incidents, but I only have a fraction of the miles on either of those.

Fair enough. I'm in synch with you. My negativity on the Michelin Pros comes from several tires lost to sidewall cuts in the 2s and 3s models. But I kept trying because I liked everything else about the tires so much. Finally I couldn't keep my head buried in the sand anymore and had to face the facts. Too bad.

Ribble has 700x23 in stock right now for $17.12 each. The 700x25 goes in and out of stock...I bought two about 2 months ago, but haven't seen them in stock since (I think the 700x25 go for $19 when they have them). Compared to the Vittoria Pro SE (also Pro II is similar) tires I was running, the Lithion 2 is definitely less of a rock. However, the nice thing about the Vittorias is that they chucked just about all debris away, and I got a solid 3,000 miles out of the rear tire before I felt it was too flattened in the middle to hold up much more. The front tire was barely showing wear. For about $20 that's pretty good wear. However, I didn't know much better for ride comfort, and can say that the Pro4 and Lithion 2 are definitely much better for comfort.
