I haven't found a better rear tire in this size. I'll probably try the new 700x35 Vittoria Terreno Zero at some point, but it's smaller and I prefer the size of the Override.

The Hutchinson Override is lightweight and very fast rolling. It's very supple, providing a smooth ride and minimal rolling resistance. The Override helped me nearly produce the same kind of speeds I experience on my road bike on pavement with 700x25 Rubino Pro tires. Performance on a wide range of dry surfaces is excellent. Firm gravel, dry grass, dry single-track are all traveled with speed and confidence. Soft and rutted single-lane gravel roads require focus and skill, but can be covered quickly with sufficient traction. Wet gravel and pavement are acceptably easy to travel if the rider avoids any excessive banking during turns. I avoid wet earth and grass, it's not the right tire for those conditions.

I completed the 50 miles Cuba Gravel Crisis with the Override. I continue to be highly impressed with the tire. Traction, durability, reliability all continue to remain at a high level. I'm unable to break the rear tire loose on soft sandy trails, unless it's a very steep climb and I stand while mashing the pedals. Simply sitting on the saddle re-establishes traction. The front tire also maintains traction well on flatter routes. However, I'll install a knobby tire, like the Vittoria Terreno Dry, on the front if I expect faster downhill sections that require urgent braking and cornering. No need to remove the Override from the rear. It rolls fast with a surplus of traction.

Raleigh Stuntman. The bike comes standard with 700c x 50MM X'Plor MSOs but I've run a variety of tires on it.

Good to know the background. I find them to be a little on the hard side on long off road/gravel and touchy on the front through mud and slick or rough (obviously, they are almost a slick). They are my primary road tire and on my mixed rides that have less than 20-30ish miles of terrain. I've done many 70+ gravel days on them before I got a second set of wheels. I just replaced my rear after about 2500 miles on it and some chords showing. Other than a single 1/8 inch slice that I patched with a standard tube patch from the inside, they have been flawless.

I am using gravelking sk in 38mm. I am not sure if I could go larger on my current bike. I would probably be happier with a bigger tire for descending mountains with loose gravel. I think they ride fine on pavement. It all depends on the state of the gravel roads that you ride on. I had 20 pinch flats the last year I rode 30mm tires, the local gravel roads feature a lot of large rocks that are barely visible, but are sticking up enough to cause pinch flats. Going from the 30 to 38 didn't slow me down at all and no more pinch flats. Of course, going tubeless had something to do with that as well.
