Rule of thumb: mostly-indoor on concrete → rubber cushion. Clean floors + maximum tread life → polyurethane.

Rubber Cushion

Smooth ride on concrete, cut-resistant, lowest cost.

Standard Indoor Choice

Hub diameter is measured across the wheel bore, not the overall wheel width.

Polyurethane Options — SPS vs. Hyload

SPS (Soft Ride) — softer 85A durometer compound with enhanced shock absorption. Preferred where the forklift crosses between indoor and occasional outdoor surfaces.

Hyload — harder 98A durometer compound with higher load capacity and the longest tread life. Best for heavy-duty, smooth-floor warehouse work.

Frequently Asked Questions

What does 21x8x15 mean?

Overall diameter (21 inches) x section width (8 inches) x press-on hub bore (15 inches).

Should I choose rubber cushion or polyurethane?

Rubber cushion is the standard for most indoor applications and costs less. Polyurethane is non-marking and lasts significantly longer in high-cycle, hard-floor environments, but rides harder and performs best on smooth, flat surfaces.

Do I need special equipment to install a press-on tire?

Yes. Press-on tires are installed with a hydraulic press that presses the bonded steel band onto the wheel hub. Most operations have this done by a local tire service or dealer.

Is 21x8x15 a drive tire or a steer tire?

It depends on the forklift model — see the matched bundle sets on this page for the drive and steer combinations this size appears in.
