♥ The tire replacement accessory comes with a wheel hub on the rear wheel, which is made of nylon and is lighter and more sturdy, making it very suitable for use by heavy weight individuals. ♥ The lightweight rear wheel of the wheelchair is more convenient to rotate and is very suitable for the elderly/disabled, who can easily use it. ♥ Anti slip tire surface, with beautiful pattern design on the rear tires, which can increase ground friction and be easily applied to heavier roads ♥ Replacing wheels with high-precision bearings can reduce resistance, ensure safe and stable use, and effectively extend service life. ♥ We sincerely recommend purchasing two wheelchair replacement wheels at once, as wheelchairs produced in the same batch have a higher compatibility when used together.
