Super

Almost a year riding Tannus tires.
My opinion of them is good.
Got no punctures along the way. That's why I have bought them.
My Bike has a drive train 67T and a sprocket 13T. I repeat 67T x 13T. It's a gear ratio of 5.15.
Fastest I went uphill (3% incline) was 50 km/h.
Downhill in my city I went 60 km/h.
Those Tires are stable. Do they have grip? Yeah. Are they hard? Yep. Are they comfortable? Kinda.
If you want to have suspension and sort of a cushion in your bike, buy normal tires.
If you want your tires to be indestructible, want to take your track bike on a ride in the city? Buy Tannus.

This Brown bike is only for training purposes. It is purposely heavy and has a gear ratio for track (as I ride it everyday) . Still Tannus tires work their charm there.
The Beige bike is a mullet 28 front, 26 rear.
The Turquoise is 26 inch.
All of them have Tannus Airless tires.

700x40c is a good tire.
Maybe the best I ever had.

I'm a daily bike commuter and was tired of getting flats (once every few months) and missing work because of it. These tires remove that problem 100%. They weren't as hard to install as I thought but it's definitely a 2 person job. I take a hit in efficiency (add about 5 min to my 40 min commute) but it's worth it never having to worry about getting a flat.

With some difficulty I was able to install the tire. The rim was smaller than it should have been, so it took a lot of muscle power to install it. However, the tire I have used again is very good.

To be honest, full tires are the best I have had.
