Tannus 26″x1.75″ MTB Airless Solid Tire

The 26″x1.75″ R-grade Tannus Solid tire, the most modern solid tire in the world. Aither 1.1 R-Grade: The perfect hardness (100psi equivalent), incredible grip and extremely low rolling resistance, finally offers 1 compound for all riders. 

The Nano Technology Foam “Aither” patented by Tannus is engineered to provide maximum comfort, minimum rolling resistance and extreme durability. All Tannus tires are rigorously tested to survive at least 6000 miles, but we have seen them do much more. Once installed, the tires do not require any attention, no pump as they never go flat, they never change pressure, and always guarantee uniform performance on all surface conditions throughout their life span. Ride Tannus Solid tires like you would any other tire, wet or dry, fast or slow, on a light bike, or fully weighed down on a cycling tour, the Tannus tires can do it all, without any bad surprises. 

Unlike ANY other bicycle tire in the world, Tannus Solid tires are TÜV Safety certified meaning they offer what no other tire can, 100% reliability, and Safety. The patented Locking Pin System ensures the tire will always stay on the rim, and the nano tech Aither guarantees incredible traction and shock absorption. 

The 26″x1.75″ Aither 1.1 is compatible with most modern MTB and city bicycles with 28” wheels and ETRTO (inner rim width) of 17-20mm. For other rim widths please check the other tire sizes. (Be sure to check you rim width before purchase) 

The 1.75” tire width means it will be a perfect upgrade for any modern “MTB bike”, converting it into a reliable puncture friendly machine, the pump, tire levers and spare tube you can now leave at home forever. 

Each Tannus tire comes with all necessary tools and fitting instructions for home installation, however it is recommended that it be fitted by a licensed Tannus fitting service to guarantee safety and performance. If you do decide to fit them yourself make sure your wheel is trued, in proper working order, with all spokes properly tensioned and, if necessary repair the wheel before fitting. Make sure to follow the provided instructions very carefully.


It is important to make sure that the Tannus tire you want will fit your rim.

Check for Locking Pin sizes that will fit your rim.

The width of your rim is one of the most important factors when determining which Tannus tire is right for you. Each Tannus tire model and size comes with different sets of locking pins for mounting the tire to the rim. Below is a chart of the locking pin sizes that come with each tire. Select a tire that comes with locking pins that are approximately 3.5 mm wider (give or take 1mm) than the INNER width of your bike rim.

Check the tire size.

Matching the tire size to what is currently on your bike is a good place to start, but you may need to select a Tannus tire that is slightly wider or narrower to fit your rim.  When in doubt, go with the narrower tire since it will be easier to install.

Tires generally have their size listed in two formats on the sidewall. First is the size in inches or cm, second is the ISO or ETRTO size. Using the ETRTO size number from your tire tends to be more accurate and less confusing. A tire with an ETRTO size marked 37-622 indicates the width of 37 mm and the tire inner diameter of 622 mm. This designation is clear and allows an unequivocal match with the corresponding rim size.

A Tannus tire needs to fit snugly into your rim to ensure a safe ride and proper mounting.

If your rim looks like it will use the smallest locking pins that comes with the tire, it will be more difficult to install. This is because the bottom part of the tire that gets pressed into the rim is a fixed width, and the narrower the rim the more work you will have to do to “tuck” the tire in under the clincher part of your rim. For narrower rims, we recommend purchasing the Installation Pliers ( P-Tool) if you are planning to do the install yourself. This tool helps to apply more pressure to the Locking Pins with less hand strength.
