Pneumatic Tires and Air-Filled Wheels

These pneumatic air-filled wheels are rubber tire-and-tube assemblies on steel rims for carts and hand trucks. Wheels in this collection range from about 250 to 350 lb per tire on verified pneumatic titles. Sizes listed include 8 x 3 in at 250 lb and 10 x 3-1/2 in at 350 lb. Air tires cushion rough pavement better than hard poly or phenolic. Check tube and rim condition before you mount a tire. Measure bore and hub length on the old wheel before you place your order today. Read the listing for the exact size and offset hub shown. Confirm the rating on the listing before you buy. Keep the load on the rating printed for that SKU. Verify the SKU matches your old unit. Capacities below are per tire unless a listing says set. Flat-free options: solid rubber tires. Full pneumatic casters: pneumatic rough terrain casters.

Air vs flat-free

  • Air (this page): softest ride on gravel and thresholds; needs inflation and can puncture.
  • Solid eco-rubber: cannot go flat; firmer ride; see solid rubber hub.
  • Foam-filled: puncture-proof with a ride between air and solid.

Pneumatic tire questions

What sizes and loads are on this page?

Primary air tires are 8 x 3 in at 250 lb and 10 x 3-1/2 in at 350 lb per tire, plus a 10 x 3 in 4-pack at 350 lb per tire.

Centered or offset hub?

Match the hub length and offset on the wheel you are replacing. Offset hubs are common on hand trucks; centered hubs are common on some casters and carts.

When should I skip air tires?

If punctures or downtime are the problem, choose solid rubber or foam-filled wheels instead of air.

Do I need a full caster or just the tire?

This page is for tire-and-rim replacements. For complete swivel or rigid pneumatic casters, use the pneumatic casters hub.
