Coast-down tests were performed with a wheelchair positioned on a two-drum dynamometer. Within each of three load conditions, tire type had a significant effect on rolling resistance (p < 0.001). The pneumatic tires had smaller rolling resistances and were less affected by load increases than the solid tires. Within the two tire types, higher air pressure or firmness and lower profile tread corresponded to less rolling resistance. Wheelchair users, clinicians, and researchers must consider the effect of tire type on wheelchair rolling resistance when selecting a manual wheelchair tire.PMID: 20104415 [PubMed - indexed for MEDLINE] Publication TypesEvaluation StudiesResearch Support, Non-U.S. Gov'tMeSH TermsEquipment DesignHumansMaterials TestingSurface PropertiesWheelchairs*Full Text SourcesDepartment of Veterans Affairs, Rehabilitation Research & Development ServiceDepartment of Veterans Affairs, Rehabilitation Research & Development Service - PDFWheelchairs and transport chairs enable those who are permanently or temporarily disabled to be more mobile, so that they can easily move around their homes and when out in public.
With wheelchairs, disabled individuals can gain greater independence in the home and go more places with minimal assistance. If you or someone you love is in need of a transport chair or wheelchair, Walgreens can help you to get the ideal model for your or their needs at a competitive price. There are two main types of rolling chairs that are used as mobility aids: transport chairs and wheelchairs. Both types feature supports for the feet, arm rests and four wheels, but they are designed to be operated differently. Transport chairs are for pushing an injured or disabled person. This type is ideal for individuals who are unable to move the wheelchair on their own and must rely on a caregiver for assistance. Wheelchairs can be operated by pushing the large back wheels on either side of the chair or by using a hand control in the case of a power or motorized chair. Many wheelchair models also have handles on the back, so that they can be pushed by a caregiver as well. Many different types of wheelchairs are available on the market to meet the needs of those who require a mobility aid.
Some wheelchairs fold or collapse for easy transport when on the go, and this type may be called a folding or travel wheelchair. You can purchase wheelchairs that have reclining seats and leg supports and bars for providing extra support for the body. Bariatric wheelchairs are designed for individuals who require an extra strong mobility device to accommodate their body weight. When you're comparing wheelchairs to purchase for yourself or for a loved one, there are many things that you'll need to consider beyond what type is right for your needs. The size and turning radius will affect how easy it is to maneuver the wheelchair to do activities like playing sports and to navigate certain settings like crowded stores. Smaller chairs are generally easier to steer, but they can be less stable. You'll also need to consider if the type of seat that the wheelchair has is adequate for supporting the body and is likely to protect the skin. The type of tires will determine which types of terrains the wheelchair will be able to safely travel.
Your doctor can help you determine which wheelchair features are essential for ensuring your safety or the safety of your loved one. Depending on your needs or the needs of your loved one, you may wish to purchase wheelchair and transport chair accessories. Special seat pads and cushions can help to alleviate discomfort, improve posture and reduce the risk of pressure sores. Cup holders and storage solutions can be added to a wheelchair, and there are also trays and desks that can be used for writing, reading, eating and completing other tasks.

Here's how it works: Anybody can ask a question The best answers are voted up and rise to the top I'm looking for a way to easily fill my wheelchair tires to 90 psi. I understand that I don't understand all the technical stuff I should consider when buying a small compressor or a tire inflator, and frankly, my head is spinning from it all. Originally, I thought I could get away with just an inflator, but it appears to me that very few of them have a minimum psi above 90.
And I'm suspicious that those numbers are inflated. I feel like the descriptions don't give me enough info. I'm having such trouble comparing all of them! Adding in the small compressors--I just can't figure this out. If I do need to go the compressor route, which I think I do, I have some restrictions in noise level and space. Some don't list if they're belt-driven, and I just don't know enough to extrapolate the missing info. Sizewise, I'm confused by the fact that sometimes smaller tanks show higher CFM than others and vice versa. I'm not looking for someone to try to explain all this to me, I guess I'm looking for someone to just advise me of what numbers am I looking for. By way of example: Would a pancake compressor which states "2.0 SCFM delivered @ 90 PSI pump, 3.5 gallon tank and 135 max PSI" work for my needs? Is one that says "200 PSI 3.0 CFM 2.5 gal 71.5 dB" going to be too much? Can someone just give me ballpark numbers to look for? I hope this makes sense to someone.
Thanks so much for your time!With the numbers you give me, could you possibly tell me what additional types of uses it might have, if any? The CFM of the compressor is the volume of air the compressor can move at the rated pressure. Your chair tires have a tiny volume just about any compressor on the market can handle them. The peak or max pressure is what you need to look at. The peak or max pressure is the value the compressor shuts down at for safety. You want this pressure to be higher than your needed pressure for losses in the hoses and the bit you loose when disconnecting the air fitting. All the pancake compresses I know of (even harbor freight) will have sufficient SCFM , if the max pressure is 125 this should more than enough to reach 90 psi on your tires once the tank fills without having to run longer than to fill the tank.
