WTB Nano Tire

I bought these tires last fall for a little gravel riding. They worked flawlessly on a few rides. The only thing I’d change is to make them wider, but 40mm is a feature, so I won’t knock them. I do a lot of road riding in the spring, and at first I left them on because I figured they’d endure the crappy spring roads better than G-One’s I had in reserve. I might just leave them on all summer. With 108 miles this week alone, I can say these tires ARE fast on pavement. I’m not even running them tubeless, yet. Better yet, when I do encounter the occasional gravel trail, I have no worries I’ll wash out. It’s all hammer down! Now, I know most are looking at these for hard-core gravel riding, and I haven’t done enough of that yet to comment. If you’re looking for a fast all-around tire that can handle both pavement and road, then given them a try.P.S. The guys at the shop I bought the bike were marveling over the tires. They have a high respect for the Nano’s. FWIW.

Daughter wanted knobby tread on her bike which she often uses for trail riding. They are for a Giant Cypress model with 28″ rims. I learned a LOT about buying and sizing bike tires doing the research on the multiple measurements (that all fit the same rim) and came a cross these which fit well within her birthday budget! They look good and she is very happy. No problem on the road or the dirt. I used her existing inner tube and swapped these out without any trouble. They are about as wide as you can get and knobby as you can get for a ‘normal’ width tire and fork assy.

Install: I put these on tubeless ready DT Swiss E1800 rims w/ Stan’s sealant. One tire installed without fuss on the first try. The second tire on the other hand was a much tighter fit on the rim and it was much more difficult to set the bead. After some furious pumping, I got the bead to set and pumped them up to 55psi. That’s when the sealant started bubbling out of the sidewall. Pumped them up to max pressure and let them sit overnight. Next day- completely flat. I pumped them up to 50psi and took them for a 20 mile ride and they were down to ~35-40psi. The tire I had the most trouble with still had some seepage issues, so I put a bit more sealant in and it was much better.Initial Ride impressions: They obviously don’t roll as well as slicks, but they feel light and very supple on the bike path/crushed limestone/ light gravel. They are also surprisingly good on singletrack. They also a mostly dry cyclocross race without any complaints.

Great tires, but they run 2-5mm smaller than advertised. They measured out to be 38mm on my wheels. Ended up sending back and ordering the 50mm and they were 45mm, which worked for what I want. Can’t go wrong with them and they offer lifetime replacement.

The side of this tire says something like “fast rolling”. The tire is great, believe me, and for such a knobby tire it is probably fast rolling. But they are indeed knobby and you feel it through the bike and hear it, and all of that is resistance. They throw up little rocks on gravel way more than any other tire I’ve had, but they also whip through soft stuff (wet or dry) way better. I set them up tubeless and while I do not see any leaks of the sealant, I do have to pump them up before every ride (which is every few days). Maybe I need more sealant or maybe it’s my rim tape. The tire was easy to mount — not too tight, not too loose. I’m happy with the tire and assuming I don’t have any issues or something, I will gladly be buying additional sets.
