WTB

Out of curiosity I bought three road tubes, intending to use them on a rim brake Fulcrum Zero wheels and having a spare in the bag. They installed easily, I just put a few pumps of air into the tube and mounted the tire/tube. The tire was a brand new GP 5K and I had to use a tire tool for the last section. Usually I'm a little paranoid about damaging a tube with the tire tool, but the tpu tube held its shape out of the way of the bead. That is reassuring if I need to install one on the side of the road.

The tubes hold pressure better than latex and are similar to butyl. I had to pump the tire up to 110psi to seat the tire before lowering it back to 85psi. No issues. I would certainly buy again.

My high expectations for tires betrayed me. I've had WTB tires in the past and they were usually durable, fit for purpose and affordable.

I was anxious to try these Macro tires on my Supercal. They are true to size mounted on 29mm internal width rims and weigh 745 grams each. I also run Vittoria inserts. I had high hopes the High Grip compound would impress but alas, I found the traction to be just ok. I'm 160 lbs and run them at 18/20 psi (WTB recommends a minimum of 20 psi) so more experimenting with lower tire pressures is needed.

These tires were a bit of a pain to mount, tight enough that I couldn't finish mounting them by hand. Once on, they beaded-up without much drama.

Also, the front tire has a slight lateral imperfection but isn't noticeable while riding.

Speaking of which, they seem to roll well in the dirt, I've had faster rolling tires but these are pretty ok.

I must say, they work well for light trail duty and have survived my past two rides on rock strewn trails with no problems, durability seems plenty good so far.

In the end, I had higher expectations for more outright grip. Not sure when but I understand a tan wall version will become available for the High Grip version.

The WTB NanoAir 700c TPU Road/Gravel tube is a decent tube. I bought 2 of them along with 2 Vittoria Zaffiro Pro Graphene 2.0 tires. One of them has probably over 1000 miles on it. And it holds air really well. I don't think I've had to add any ever since I put it on the bike. The other one got 2 pinch punctures and another puncture the first ride out and all at the same time. I tried patching the punctures. But, I couldn't get it to hold air. Which was really disappointing to me. Because it didn't hurt the tire at all, and there were no punctures in the tire. But, to be totally honest, I plowed down a chip seal road that has some really bad spots in it. So I'm not surprised that it may have gotten one pinch puncture. But, the other one and the other puncture was an unpleasant surprise. I'm probably going to get a few more for spares for my other bikes. Because they don't take up much space in my seat bags. And I have a tendency to also get a lot of punctures on my gravel bike. And I occasionally get punctures on my other bikes if/when I'm being careless.

Bought some of these tires for my gravel and single-speed bikes. On WTB and DT Swiss hoops, mounting them was easy-peasy and they are set-up tubeless with Orange Seal endurance.

Ride quality on pavement and hardpack

dirt/gravel is good. They feel like less effort is required to keep them moving with the tread center slick.

Not sure if the Vulpine S better or worse than Vittoria T30 Terrene's. Right now, I'm leaning towards the WTB's are less ideal than the T30's.
