I ride 700x32mm on my Checkpoint 6 gravel bike. I have 2 sets of wheels for this bike and I use a set with 40 mm gravel tires for the gnarly gravel roads and the 32ï¿½s for the chip and seal roads in southern Illinois.
I chose the Schwalbe Pro One TLE for the range of tire widths and quite frankly, for the TLE, TUBELESS EASY! I had previously used Continental GP 5000 TL and they were so difficult to mount that I would almost cry if I had to. And yes, they did mount easily. But would they ride as well , roll as well, and last as long as the GP5000s? Yes they did.
When my high wattage tire snob son needed tires, I recommended the Pro One TLE. He loves them
I got one of these in 2021 for the rear wheel of my Crosscheck, and wow, what a tire! I use this bike as part of a rotation, so about a quarter of the year, for 12-20 mile daily rides to/from work, for errands, and for recreational rides around the city. It is a heavy tire, but it rolls and grabs well. Like other reviewers, I was attracted to its durability. We're about 1200 miles in, and the tire looks pretty much new still. This is a tire for anyone who is okay adding a little weight and sacrificing a little speed for some peace-of-mind. And I'm not sure if the speed sacrifice is even that great. I have opened it up quite a few times, and you can still fly with these on your ride.
700x30 (BTW) I'd hoped these would be the magic, no trade offs, perfect-blend-of-traction-and-roll tire that everyone has talked about. Alas, they don't roll nearly as well as supple road tires. Oh well, they are the widest tires I can run on my road bike and they stick to everything - rough gravel, loose gravel, rocks, roots - almost everything I've run them on. I'll keep them around, on a set of rims that I use for rough roads. I'll stick to my beloved Vittora Corsa for smooth roads and days that I want to feel my tires to roll effortlessly.
This is a good tire to balance street and dirt riding. I haven't tried it on dirt, but the knobs look decent for digging into loose over hard or getting over wet rocks and roots. I wouldn't suggest these as a off-road only tire, as the center knobs don't have gaps for grabbing rock/roots. I don't think these would shed mud well either.
On the road, they roll relatively fast and don't make a lot of noise. The rubber compound is softer than a standard road tire, so you will get above average grip, especially on uneven surfaces and poorly maintained roads.
