It has been some time since the last update on the Nano 40 TCS tires here, but I have several miles on them now and I have tried them on another wheel set to see how they might mount up on non-WTB rims. The last update here can be seen if you click this link. That will take you back to see how I felt the tires worked tubeless on WTB rims and there is more there as well. Right now, let me give you a quick idea of how these tires have worked on another wheel set and then I will give an updated ride performance viewpoint.
The Nano 40 TCS tires are based upon a UST type dimension, so Stan’s wheels may not be a best fit for them. I chose to try the Nano 40’s on my set of HED Ardennes+ wheels, which were designed with tubeless use in mind. I used a Velocity USA “blue” tape and the Nano 40 TCS tires aired up with a weak floor pump easily. I have been able to run upwards of 50 psi and as low as 30psi with no adverse affects on “normal” gravel riding. Air retention has been really good for me, but remember- air retention has as much to do with your sealant as it does with the tire/rim combination. The sealant I use, which is not available commercially, has worked very well for retention of air, not to mention sealing punctures. So, if you aren’t seeing great results in terms of air retention over time with any particular tire/rim, it may be time to think about the sealant you use.
Finding out that the Nano 40 TCS tires worked well with the HED Ardennes + wheels was a good revelation, as the wide rim gives these tires a great, puffy profile, and the ride comfort has been really good. Rolling resistance is slightly better than a tubed Nano 40, but the level of comfort is greatly increased. You can easily feel that the tubeless Nano 40 is smoother feeling over the chatter and bumps.
The tread pattern works well on dirt too. You can really get a nice bite on dirt tracks in the corners with this tire and the tubeless nature of the set up allows for even better grip than I experienced with the tubed Nano 40’s. The tubeless set up also makes for a slightly less buzzy feel on pavement, but you still can feel that this tire has some serious tread. Gravel riding is very good with this tire as it also damps the vibrations well due to the tubeless set up, and the tread pattern along with the tire profile both work to lend some stability to the ride.
So Far…. Great tubeless performance, but a tad heavy for this size tire. They hold air really well and the Nano 40 TCS seems to roll very smoothly. They work on non-WTB rims from HED, and likely on others as well, but may not fit very good on Stan’s rims. The ride performance has been very acceptable with a noticeably damped feel compared to tubed tires.
Stay tuned for the “At The Finish” post on these tires
