Continental

Have had more flats with the 2.4 Dubnital than the 2.2 Race Kings. Maybe pressure and width and riding style are playing into it, but seems like a bit of a regression in toughness. Never had to plug a Race King, but less than 500 miles and I've got 2 plugs in my rear Dubnital.

Still roll well and have good handling characteristics for my terrain, but would probably look somewhere else for riding in rocky terrain that is tough on tires.

I'm new to the game of tubulars (sew-ups) and have been looking for a more puncture proof tire. I had been using Vittoria clinchers so I thought I'd try their tire. What a disaster! The Vittoria's didn't last and even worse were their valve stems. They were too big to fit through the rim--nuts! I put on the Gatorskin and perfect. They seem to have superior quality and to me they roll far better.. Subsequently, I found out that Vittoria moved to Asia for manufacturing while the Gatorskin is still made in Germany. That's a pretty good bet that the environment is better off. I will buy more of these.

I got these after using the Grand Prix Continentals, which run beautifully, but are pretty vulnerable to bits of glass and other puncturing objects. So far, these have lasted well, but still peddle very well. I ride daily on the local bike trails, most of which are paved if a bit bumpy, with unpaved (gravel and crushed rock) intervals. I ride one of the old Raleigh Technium mountain bike, but with these narrow, high-pressure tires because I don't generally go off-road, and, besides, there are no mountains in Illinois!

700x32 replaced a same size Specialized Pathfinder Pro on the rear - so far only about 150 miles, but gotta say it's phenomenally low rolling resistance - running at ~50psi tubeless for ~160# bike & rider. Using a pull-over tool it was easy to install - might have got by with just levers. Primarily pavement, but have dabbling in a bit of gravel & hardpack make me confident to ride them through whatever I encounter. Very pleased so far.
