Are Solid Tires Good?
Now more and more wheelchairs and scooters with pu solid tires, so pu solid tires are good? What advantages does the pu solid tires have over pneumatic tires?
Most people need pu solid tires because they have the following advantages that air tires cannot match：
A. Eco-friendly: The pu solid Tires do not have bad effect on the ozone layer and are 100% recyclable.
B. Inflation-free: The airless tyres are non-pneumatic tires keeping users away from the worries of flat tire,air leakage.
C. Noise Reduction: The polyurethane has the effect of shock absorption, sound-absorbing,making users feel comfortable while in use.
D. Puncture Proof: The airless Tyres are solid tires that are no afraid of nails, shards, or broken piece of glass.
E. Maintenance Free: The pu tire is solid structure and not air pressure for load support.They cannot leak or go flat, and never need to be pumped up or repaired. The solid tires are maintenance free, which allows wheelchair users with limited mobility to not have to worry about having to be stranded at the side of the road when their wheelchair suddenly breaks down during use.
Why can't solid tires with such advantages replace pneumatic tires?
The reason are as below:
A. The solid tires are heavier than that of pnematic tires with the same size;
B. The solid tire's shock absorption performance is not as excellent as that of pneumatic tires.
Although the micro-porous inner wall structure（as below picture） of PU solid tires also has a shock-absorbing effect. This can only meet the basic daily needs, if the wheelchair user requires particularly high shock absorption effect, compared with that, the maintenance-free performance is not very important for them, then it is still recommended to choose air tires.

Solid tires and pneumatic tires have their own advantages, the choice depends on the user for which performance is more focused. Of course, you can also go to the dealer's store for a test ride to experience the actual effect of both tires.
