Crown Press-On Polyurethane Tire 15 x 9 x 11.25 – 10440-A

Pressed directly onto the wheel rim under hydraulic force rather than inflated, this Crown press-on polyurethane tire measures 15 by 9 by 11.25 inches and is built in the A compound formulation for Crown lift trucks. Running solid poly means there is no air to lose, so the tire cannot go flat and holds a constant rolling diameter, which matters for ride quality and for any speed sensing tied to wheel rotation.

In a load-bearing or drive position, the polyurethane compound governs how the tire behaves under weight, with different formulations trading among cushioning, load capacity, and resistance to chunking and heat buildup. As the tread wears down, the tire loses cushioning and can develop flat spots from repeated stops under load, felt as a rougher ride and, in a drive position, reduced traction.

At 15 by 9 by 11.25 inches in the A compound, it is sized to the Crown platform it was cataloged for. Match the three dimensions, outside diameter, width, and inside diameter, to the wheel, since a press-on tire has to seat correctly on the rim to run true.
