12 1/2X2 1/4 PU Solid Wheelchair Accessories
1. Product Introduction
Crafted from microcellular elastomer, our polyurethane tire offers excellent resilience and a unique micro-porous inner structure that effectively absorbs shock and dampens sound. This design delivers a remarkably smooth, quiet ride, making it the ideal choice for super-silent applications.
2. Applications
Thanks to its outstanding advantages-puncture-proof construction, superior cushioning, low noise, high safety, environmental sustainability, zero maintenance, and long service life-the PU tire is widely used across a variety of mobility and transport equipment, including wheelchairs, mobility scooters, bicycles, strollers, electric scooters, utility carts, and more.
3.Polyurethane Tire's Production Process And Size Range
Our PU solid tires sizes are as follows:
4x 1 1/4, 5X1.5, 6X1 1/4, 6x2, 7X1.5, 7X2, 8X2,8x2.5, 9x3,10X3, 12 1/2X2 1/4, 14x2.125, 20x1.5, 24x1.25, 24x1.5, 24 1 3/8 etc.
4. Key Features and Benefits of Our Solid Polyurethane Tires
(1) Weather and UV resistance – Formulated to withstand prolonged exposure to sunlight, oxygen, ozone, and other environmental factors, ensuring stable performance outdoors.
(2) Chemical resistance – Impervious to water, oil, dirt, acids, and alkalis, making them suitable for workshops, medical facilities, and outdoor terrain.
(3) High load capacity – In our internal tests, a PU tire consistently supports up to twice the weight of a comparable rubber tire without deforming.
(4) Puncture-proof – Since they are solid, there is no air chamber to rupture. Nails, glass shards, or sharp debris won't cause a flat.
(5) Maintenance-free – No air pressure is needed; they never leak, go flat, or require pumping. Once installed, you can simply forget about them.
5. In‑House Performance Tests
To verify long‑term reliability, we run every batch through a series of simulated real‑world tests in our factory:
Rolling drum test (endurance under continuous rotation)
Tension/compression force analysis (structural integrity)
Side impact (lateral shock resistance)
Drop testing (impact from height)
Static load (creep and deformation under sustained weight)
Circle track (turning and cornering behavior)
Coefficient of friction (grip on various surfaces)
Torque measurement (rolling resistance)
Noise test (acoustic performance)
Bump test (ride comfort over uneven surfaces)
These procedures help us catch any issues before products leave our facility.
6. Certifications
Our solid tires meet internationally recognised standards, including:
ISO9001:2015 (quality management)
ROHS 2.0, REACH, PAHS, EN14372:2004, and TUV Rheinland – ensuring compliance with safety, environmental, and material restrictions for global markets.
