Is It Better to Choose Solid or Inflated Tires for Electric ...

Electric wheel chairs for the elderly have many uses and are favored by consumers. Electric wheel chairs for the elderly are constantly innovating in the selection of materials and functions. The materials have changed from iron pipes or steel pipes to aviation aluminum alloys. The functions can only be manually controlled before, and now only the controller can be used for electric walking.

Many customers have been asking whether the mobility wheel chair is solid or inflatable? Buying a wheelchair has always been hesitant, so consumers are struggling with which one to choose. So are wheelchair tires solid? Wheelchair tires have the difference between solid and inflatable inner tubes. Many solid tires are the most common type. They walk faster on flat ground, are not easy to burst, and are easy to push. Let's learn about wheelchairs and electric wheelchair tires together.

&#;. Wheel chairs are suitable for the following diseases

Spinal cord injury, lower extremity disability, craniocerebral disease, the elderly, infirm, sick people, the correct use is very good. When choosing a wheelchair, the cognitive function of the patient and at least one upper limb with normal function should be considered, and the wheelchair can be operated with familiarity.

&#;. Wheel chair tires include solid tires and pneumatic tires

So, which of the solid tires and pneumatic tires of the wheelchair is durable? Here I can tell you for sure that solid tires are definitely more durable. The solid type travels faster on flat ground and is not easy to explode and is easy to push, but it vibrates greatly on uneven roads, and it is not easy to pull out when it is stuck in the groove of the same width as the tire; The vibration is smaller than the solid one, the tubeless inflatable type will not puncture because the tubeless, and the inside is also inflated, it is more comfortable to sit up, but it is more difficult to push than the solid one. Mobile wheelchair solid tires have the following characteristics, you can refer to the following:

1. Don't be afraid of puncture, don't need to pump up, save you the pain of pushing the tire to repair the tire.

2. Good cushioning performance makes your driving safer and more stable.

3. It is not affected by the weather, and will never burst due to overheating in summer.

3. The difference between solid tires and pneumatic tire wheel chairs

In terms of shock absorption effect and comfort, pneumatic tires are better. From a cost-effective point of view, it is also a good pneumatic tire. Considering the economy of using the engine, it is better to use pneumatic tires. In terms of durability, solid tires are better. The shock absorption effect of pneumatic tires is good, and the push time is relatively light, and the solid tires are convenient and do not need to be inflated. It is suitable for the elderly who are inconvenient to cheer up.

Through the above analysis, we believe that everyone has learned that there are different advantages of pneumatic tires and solid tires for mobility wheel chairs. We hope everyone can choose a wheelchair that suits their needs, which is durable and comfortable.

This blog post examines the functional implications of tire selection and discuss what options are available. Like the biking industry, tire selection should be chosen for intended performance and terrain to be utilized on.  There are a wide range of maintenance and cost differences, but these should  be considered after the performance requirements are determined.

For the purpose of this article, we will discuss differences in types of tire, including performance, terrain, and maintenance, depending on selection.

Pneumatic

With a higher performance ultralightweight manual wheelchair, a higher performance tire is recommended. This usually means an air or pneumatic tire. This is also the lightest option when overall weight for optimum propulsion, or independent lifting of the chair is the end goal. Air tires also provide the best shock absorption and vibration damping. Clinically this can help with pain control and spasm management which can be often overlooked due to the maintenance requirements. There is often a no-cost pneumatic tire option given by manufacturers, but this may not give the best performance. Knowing how the chair will be utilized within the user&#;s environment will allow for the best clinical decision making.

There is a range of high pressure and treaded pneumatic tires available on most wheelchair order forms that can be selected based on the user&#;s specific performance needs.

While they do require some maintenance, pneumatic tires are the optimal choice for propulsion efficiency and comfort.  Kwarciak et al looked at solid vs pneumatic tires in different tests for efficiency. The evidence clearly showed that air tires are the most efficient and at 50% of recommended inflation (or 50% flat) they still rolled with less resistance than a solid tire.

All manual wheelchair users should be informed of the pros and cons of pneumatic tires, and given a choice to optimize performance. 

Solid/Urethane

A solid/urethane tire requires little to no maintenance and can be utilized with an ultralightweight manual wheelchair if the user is unable to maintain air, either themselves, or through a caregiver. While they are essentially maintenance free, performance and ride are significantly different than air. There is little shock or vibration absorption, and very little traction, leading to a bumpy and often uncomfortable ride outdoors, but performs well on indoor flat surfaces. They also are heavier and have increased rolling resistance, which has been demonstrated in multiple studies.

Pneumatic with airless insert

A third category is pneumatic with an airless or foam insert. This technically allows for the &#;feel of pneumatic, with no maintenance of a solid tire.&#; Unfortunately, this can add up to 1.5 times the weight of a pneumatic tire as well as significant rolling resistance, decreasing the overall performance of the chair and making it more difficult for the user to self-propel.  There is also more wear on the tire which can be difficult to change when the tread wears out.

Tire tread also contributes to the overall performance.  A larger knobby tread is better for traction, outdoor, and wet surfaces. A smooth, narrow, high pressure air tire is best for speed and maneuverability, both indoor and outdoor.

There are a wide range of tires in each category that have specific advantages and disadvantages; for example, there are many tires that are puncture resistant, or have varying levels of tread depending on environment. It is important for the clinicians and suppliers to understand the options and realize the importance that tire selection plays in overall wheelchair performance.

When deciding on tires, knowing lifestyle, environment, and preference can help determine what will be the best option. Do not make assumptions regarding maintenance and ride characteristics and involve the user in the selection process. Educate and empower with choice and allow the user to try different tire types. This will allow them to get the &#;feel&#; for the roll and could significantly enhance overall experience. Some users may choose to purchase a second set of tires and wheels to allow for easier access to multiple terrains. Best practice is matching the user&#;s need with the best performing material for them, not &#;what requires the least maintenance&#;.

Paying attention to the user&#;s needs and goals will allow for best matching of components to their lifestyle.

To summarize, some of the advantages and limitations of the three types of tires are included in the list below:

Pneumatic Tires:

Advantages:

• Generally lightest
• Shock absorbing
• Good traction on most terrain types
• The right amount of tire pressure can offer a softer ride over bumpy surfaces and provide that tactile grip which is important on wet surfaces

Limitations:

• Requires regular maintenance
  • Tires should be checked weekly
  • Inflation needed 1-2x per month

Solid/Urethane Tires:

Advantages:

• Designed to be fully puncture proof and low maintenance
• Durable against chemicals, sharp objects
• Wears at a slower rate
• Typically has higher tensile strength allowing it to carry heavier loads.

Limitations:

• Less effective on rougher terrain
• Heavier than air tires
• Recommend for indoor use (unless treaded)
• Usually a rougher ride
• Increased rolling resistance (poorer performance)

Foam Filled (Solid Inserts):

Advantages:

• More grip than solid/urethane tires
• Softer ride than solid/urethane tires

Limitations:

• More rolling resistance than pneumatic or solid/urethane tires
• Heaviest option
• Does not perform optimally outdoors
• Difficult to maintain over time
