Description

The WTB Nano 40 is built for speed—added SG2 Protection will keep you hammering

A nearly uninterrupted centerline provides swift efficiency on hardpack terrain while staggered outer knobs allow you to stay on the gas while mashing up chunky climbs or hanging on through loose gravel corners.

The high-volume 40mm casing allows for lower tire pressures and a smoother ride while still reducing drag and rolling resistance. This makes for an all-out gravel destroyer that still appeases those clamoring for a truly big cyclocross tire. Everybody's irrefutable favorite, 'nough said.

Take your tires to the next level with SG2

This version of the Nano features WTB's all-new SG2 puncture protection. This new protection layer is a lightweight, ultra-thin nylon insert that provides bead-to-bead coverage to ensure all surfaces of the tire are provided with an additional level of defense against punctures.

Exactly how much more durable are they? Lab tests show the addition of the bead-to-bead SG2 puncture protection layer to a 120tpi casing provides 33% more sidewall protection and 17% more tread protection than the standard 60tpi offerings without SG2.

While SG2 is primarily a puncture protection layer, its tightly woven fibers also improve air retention, which prevents seeping at the sidewall and helps maintain pressure between rides.


Features:

  • A dense dual DNA centerline keeps these tires fast on the hardpack the aggressive side knows are grippy in the loose
  • Super-supple 120tpi casing
  • Tubeless-ready
  • Extra-durable SG2 Puncture Protection to keep you rolling over the most demanding terrain

I've put 1500+ miles on these from last summer, through the winter and well into this spring. I bought them on a suggestion from a buddy, and am glad that I did.

These have been rock solid and do a great job at being all 'rounders. Enough bite and grip for most surfaces but the loosest/wettest conditions. Decently fast on tarmac, but not the fastest. The only situations I've found these to lack is in wet/muddy or snow/icy conditions (although they do better here than my previous g-king sk's) and they lose a bit of grip in sandy/loose corners. Nothing that don't also trouble all tires I've ridden to be fair.

I'm going to try a drier tire next for the coming dry season, but would not hesitate to buy these again.

I've ridden Nanos in the 40 width for four seasons now. They hold up well, wear well, and perform nicely on both pavement and gravel. They also work well on dirt single track. Traction is very good in a variety of conditions and they corner well. I've been able to run one set for an entire year, usually, riding 6-8 hours a week, on average.

I've found the 40s measure closer to 38-39 and fit in my frame when other 40s won't. The width gives me a soft ride at 26-28 psi while not risking my wheelset to rock damage. In the Utah winter, I rely on Nanos for 2-3 hour road rides with some patches of snow or ice.

I really, really wanted to give these tires a go but the sidewalls are so thin that the tire flops around all over the place when you are trying to mount for a tubeless setup. I tried everything I could practically think of but tubeless is seemingly impossible for these tires. I would return/exchange except I've had these for a long while collecting dust as I thought I could win this battle. Now I guess I'll try and sell them at a loss. Not sure I'll be trying another WTB tire on my dime. I'm sure they are a nice tire but I didn't buy them to run with tubes for my first tubeless setup. I ended up trying a tire from a different brand and the process was so easy. Maybe a strap around this tire would help or maybe one of the foam liners for flat protection would make things easier but at this point I'm cutting my losses.

Are you looking for Jeep tires for your gravel bike? These are them.

Are you single-track-on-your-gravel-bike-curious? They do that.

Do you like to taunt roadies with that "rahr, rahr, rahr" sound as you creep up on them? These are for that too.

They are my goto all road tire for daily ramblings. I don't ride a mountain bike, I just pretend my carbon fork is invincible...

Now, the things they are not the best at:

* Fast cornering through sketchy, soupy gravel

* Mud - like most gravel tires, they don't shed mud very well

I bought these WTB Nano 700c TCS Light SG2 Gravel Tires to replace a more aggressive tire. Rode more on a combination of gravel/pavement/cement, and I just wanted something a little faster/smoother. These WTB Nano's still provide the grip I like like/need but also have increased my speed a touch and provide better efficiency.
