20 x 1 3/8 in. (37-451) Primo Express Urethane Wheelchair Tire

The 20 x 1 3/8 in. (37-451) Primo Express (Xpress) Urethane Wheelchair Tire has a higher profile tire with rounded tread and slight notches in the center which provide a smooth comfortable ride. Solid urethane construction will ensure you never get a flat tire.

• Fits most 20 x 1 and 20 x 1 3/8 (451 mm) wheels that have a hole for an inner tube valve stem.
  
• Latex free.
  
• Sold individually (each). For a pair, please order a quantity of 2.

Fitment Notes
This tire will fit most rims that have a hole for an inner tube valve stem. If your existing wheelchair rim does not have a hole for an inner tube valve stem, chances are this tire will not fit. This is also the tire that Sunrise Medical uses for several of its Quickie model wheelchairs (Sunrise part 386232)

Installation Notes
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. 

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