We got this for use on a wheelchair with inflatable rubber tires. Getting to the valve on the wheel is problematic, but that would be the case with any pump. This does work very well to inflate the tires and is small enough to keep with the chair so it can be used at any time. Highly recommended!!REVISED: After a few months' use, the device became problematic. No amount of pumping would increase the tire pressure. It's now useless. Shame.
