Q: A 700x35c - 44c (27x13/8) tube fits my road bike tire, will the airless insert work for my tire? Thanks
Asked by:  - 5/6/2015
A: sorry, no body makes an airless insert to fit into a 700 x 35 tire at this time, another option may be the Laguna airless tire http://www.airlesstiresnow.com/Nu-Teck--Marvel-Compound-City-Tread-Airless-Tire--Options_p_253.html

Q: My tire has on it 23-622 (700x23C) Will your 700x23C (25-622) size tube fit this?
Asked by:  - 4/30/2015
A: No, the reason is that the insert needs a really wide rim to make it fit or the tire should be slightly larger like 700 x 28, but these are not for road bike, please look at the Airless Tires like the Daytona 700 x 20. Inserts or Airless Inner Tubes can be very stiff and are meant for high weight situations where the terrain is very smooth. In the future we hope to change that but for now, please consider the Airless Tire as a better option

Q: Do you import to Australia, or can I order these tubes directly from you? Thank you in advance.
Asked by:  - 4/20/2015
A: yes, we ship to Australia all the time. We use a third party shipper who takes any overseas order we have and they ship to you via US Postal Service Priority Mail which is the cheapest way there to send something overseas.

Q: I have a 650c wheelset which is 23" (small womans Tri bike) with 650x23c tires. Will any of these sizes fit? are there alternative airless tire solutions?
Asked by:  - 1/15/2015
A: sorrowfully we must say that there isn't much for your size, these inserts are not what you need. as these are quite stiff and meant for heavy duty things not fine road bikes. The 650c tire selection shrinks every year too as more and more manufacturers quit making that size. The Continental Gatorskin is a tough tire that is still in production, good luck

Q: my tires say 54-559 so what airless tube will fit and what is the price?
Asked by:  - 5/28/2014
A: your tire is too large for one insert and not big enough for another, decide if you need a wider or thinner tire, order the insert, then go to a bike shop and find a tire to fit the insert

Q: I am purchasing a Busetti electric tricycle to go on rather long rides away from home on bike paths (sometimes on city streets). I am in my 80s. I don't want to get stuck away from home with a flat tire. Would these tire serve my purpose? And are they relatively easy to install? ........George
Asked by:  - 5/28/2014
A: maybe, need to make sure they will fit, look at the Stop A Flat, are lighter, will be easier to install, another option and more traditional is the almost flat proof schwalbe tires we sell

Solid Airless Foam Urethane Inner Tubes you stuff inside your bicycle or wheelchair tire.

Before you purchase

The manufacturer of this products asks all who purchase to understand that these "Solid Inner Tubes" require a good fit to work. They are also custom made and cannot be returned. Please take care before ordering. Please listen to the audio and watch the slide show before purchasing.

As a service to our customers who purchase these, we offer a No Hassle Return for $8.00. If you choose the No Hassle Return, then if you should for any reason need to return them, we will take them back no questions asked. The fee is per order.

The Kenda Brand insert is very hard and stiff and have been developed for Medical devices. They fit bicycles but the rims needs to be very wide. (At least an inch across). If you need a softer ride, look at the Stop A Flat which uses a softer material.

Getting the right fit means knowing your "ISO"

Every tire has a set of numbers like "26 x 1.95", but every tire also has another set of numbers in smaller type that looks like "47-559".

A 26 x 1.95 could be a range of sizes, but the actual size is imprinted on every tire in a five digit number known as the ISO number.

If your tire ISO width is less than the ISO width of the Inner Tube do not use

If your tire ISO width is no more than 5mm larger than the ISO width of the Inner Tube then use

If your tire ISO width is larger than 5mm wider than the ISO width of the Inner Tube, do not use

Rating Kenda American Airless 26 x 2.125
Hi, just got a set of these Kenda airless inserts recently, in the 26 x 2.125 size. The inserts are a grayish, proprietary urethane compound. You will receive exactly enough of the material to fit a tire of the 26 x 2.125 (ISO 57-559) width range. Hopefully in the future they'll do production with dedicated molds, for the larger inserts. These 26 x 2.125 inserts fit optimally (with less-or-no slack or kinks), if the tire's inner surface distance bead-to-bead 'circumference' (i.e. unfolded or 'opened' distance) is between 125mm and 130mm. Especially if fitting tires at the lower end of this range I recommend to have 2 or 3 *Downhill Tire Levers* to make the task easier and safer. Safety goggles and safety gloves are also recommended for the task. Examples are: * the Kenda Kwest 26 x 1.95, which has a slick road tread, and bead-to-bead tubular inner circumference of 130mm. * the Serfas Drifter 26 x 2.0, which has an inverted semi-slick tread for both good rolling and traction when needed. The Drifter 2.0 has an inner surface bead-to-bead distance of 125mm. You will need 2 or 3 *Downhill Tire Lever* tools to install this tire with the inserts. The Kenda American Airless inserts are a bit heavier than pneumatic tires, but they roll very well for heavier riders such as myself (@ 230-250lbs).
