Benefits of Aero-Flex™ Solid Urethane Wheelchair Tires
The Aero-Flex™ material is made up of thousands of microscopic honeycomb-like cells formed by a matrix of a tough urethane elastomer. Benefits are many including:
  • Low rolling resistance making the wheelchair easier to propel
  • The Aero-Flex™ material provides excellent shock absorbing properties for a superior ride
  • Excellent load bearing capacity - ideal for standard to bariatric (high weight capacity) wheelchairs
  • Lasts 2-3 times longer than standard air filled nylon tires
  • Outstanding resistance to cutting and tearing
  • Completely flat free - no more worries about nails, glass, or pinch flats
24 x 1 3/8 in. (37-540) Aero-Flex™ Urethane Wheelchair Street Tire Fitment Notes
This tire will fit most 540 mm sized wheelchair rims. You’ll know you have a 540 mm rim if the existing tire size is 24 x 1” (23-540 mm), 24 x 1” (25-540 mm), 24 x 1 1/4” (32-540 mm), 24 x 1 3/8” (37-540 mm). You can confirm the size by looking at the size stamped on your existing tire. In most cases your rim will also have a hole for an inner tube valve stem (meaning the rim is of a standard size). If your existing tire is a pyramid design (smooth flat top) on a plastic rim, or is not stamped with the 540 mm size, this tire will most likely not fit. This tire will replace most tires used on Quickie, Top End (Invacare), TiLite, or any other wheelchair where the rim has a hole for a valve stem. It will also fit most rims including rims from Spinergy, Primo, and X-Core that have a hole for an inner tube valve stem. 

Installation Note – Please Read Before Purchase
Installing these tires onto a wheelchair rim can be very challenging without the proper tools. This is because the tire itself is smaller than the wheelchair rim and needs to be stretched onto the rim. If you do not have the ability or the tools to properly install these tires, it is advisable to seek professional help. You cannot install this tire by hand! Please note that EnableYourLife.com will only accept returns of undamaged / uninstalled tires.

If you have a properly mounted bench vise, you can purchase a solid tire installation tool which can be found on these pages:

Great to work and order from. Efficient takes no time at all and you get the proper part
   Good everyday tires, November 25, 2022  By Stephen (Studio City, CA)(Verified)
long wearing and works well with my Spinergy setup. Not the great price they once were though
   Good replacement, January 14, 2019  By J (San Antonio, TX)
Good replacement. Make sure you order the tire mounting tool. Even with that it took a lot of strength. Useful tip is leave the tire in hot water to soften the rubber. Then use soap and water to lubricate the mounting tool.
   Good tires, January 9, 2019  By Christie (Phoenix, AZ)
Replaced air tires using a solid inner tube. Tread is the same but the tire feels more agile and my WC rolls pretty easily. They were tough to get on using your tool but my friends were able to manage (with me cheering them on!). I''m hopeful they will last awhile.
   Wheel Chair tire installation, February 6, 2018  By Harold Wingler  (Terre Haute, IN)
Tires are a little difficult to install, but the special tool makes a great difference. I''m going to say it still takes four (4) hands to accomplish. If you are going to mount them yourself the tire tool will be a definite advantage. Order a Snap-On Vice Tire Setter, from
http://www.ocelco.com/, instructions accompany the tool. You will have less than $100.00 in the tires and the tool!! GOOD LUCK!
   Hard to install, December 18, 2017  By Anonymous (Atlanta, GA)
Way to hard to install. Tried to do it myself by watching youtube but forget it (my upper body strength is not the greatest). Had to pay 50 dollars to have them installed so they are not the great deal I thought. But now they are on and seem pretty good.
   Good tire, November 9, 2017  By Timothy (Chicago)
Good tire
   Decent tire and not too expensive, September 8, 2017  By Albert  (Harrisburg, PA)
I put these on a set of wire spoke wheels i got from EBAY for my sons wheelchair. These tires feel way more substantial than the kik (never heard of them) tires that were on there. Had them in two days CA to PA - thats crazy fast shipping. Thank you
   Not a fun experience, August 10, 2017  By James (TX)
No worth the aggravation to find an installer. I finally did but it cost $$$. I should have kept air filled tires and gotten heavy duty innertubes
   Great, June 1, 2017  By Billy  (SF, CA)
I replaced a set of shox tires and I have to say they make the wheelchair feel like it can tackle any surface. They are a little wider and taller than the Shox (I had to adjust the brake forward a little). I found out they are made by the same company so I''m guessing the material is the same so maybe its the more aggressive tread. I got what i thought was black but it is dark dark gray.
   Good so far, May 11, 2017  By john on wheels (KY)
hopefully they last longer than the express tires i replaced
   Good but tough to install, March 30, 2017  By Dan (Denver, CO)
These tires are really good and they have the same tread as my old ones but as others have noted they are tough to install. I watched my brother in law struggle for 1/2 hour. If it wasn''t for the install, I would have rated 5 stars
   No more air!, February 2, 2017  By Michelle (New York, NY)
Excellent replacement for the air filled tires on my daughters wheelchair. They even look the same. Had to pay extra to have them installed but it was worth it as i will never have to fuss with that air pump again!
   good tires, January 5, 2017  By Lindsay (Surprise, AZ)
I broke one of the tires trying to install. Called and got another tire with the installation tool and was able to install no problem. They feel pretty good but I wish you had them in blue to match my chair (quickie2)
   good but...., October 13, 2016  By Anonymous 
they should be easier to put on
   Good tires, September 30, 2016  By Manuel (Chicago, IL)
I replaced the stupid flat top tires that came with my moms wheelchair - wow what a difference. Drive, are you listening?
