Vittoria Terreno Zero G2.0 650b Gravel Endurance Tire

BRR has reviewed an older version of these in a different size, and if you were to extrapolate that data then these probably aren't super fast tires, but I've had good experience with Vittoria and decided to give them a chance. There's not a ton of options at 650b.

One tire weighed in a 581 and the other at 558g, which is a good result vs the advertised weight. They look nice, and the rubber has a svelte and tacky feel in hand. So far so good.

Mounting the tires on the rims was fine, not particularly hard or too easy. Getting them to seat was difficult, which was surprising to me. I've only ever had issues with cotton sidewall tires. I had to use a tube to get the beads to seat, and then removed the tube unseating only one bead. Then inflated again and the tire was seated tubeless.

Unfortunately for me, my bike doesn't have a ton of clearance, and these may run too big for me. I'm still undecided if I want to give them a shot or not. The rear tire measured 50.3mm on my 25mm inner width rims (hookless) right after installing, and that's cutting in very close. If the tires stretch out I'd be in trouble. I'm used to most tires running a little smaller than measured initially and then stretching out too close to their stated sizing.

One other note, the rear tire has been inflated with no sealant for two days and was at 25 psi when I checked it just now. Never seen a tire hold air that long without any sealant.

I installed these on my Scott Scale 29'er. My riding is 90% on paved trails, 10% on hardback dirt trails. I chose this tire because I no longer do any mountain biking and wanted a smoother rolling tire for my mountain bike. I've been very happy with the ride and longevity of these tires. I usually run them at 65psi.

I just put a new pair of these on my bike. The last pair had 2000 miles on them and I probably could have ridden them for a few hundred more miles but the tires, had numerous small slices in the tread due to wire cuts, glass, sharp stones (apparently.) I never experienced a flat on the first 1800 miles. As fate would have it, I was plagued with 5 flats during the last 200 miles. Two were due to sharp wire (what I assume is from exploded tire debris on the side of the road), two were punctures due to running over Goat's Head weed and the last was due to a tiny, sharp arrow head shaped stone. So I finally decided to just buy new tires at that point. I've already gotten another flat with the new tires due to a tiny sharp wire. Dang. Really not the tires fault though and overall I think these are great tires for the trail riding that I do.

I am hard on tires, but I have had good luck with Vittoria Terrenos in the past. This time, both of these tires had numerous visible cuts and multiple plugs after about 250 km running tubeless. I removed them and switched to something hopefully more robust.
