What It Is

This is a pack of four 20x8.00-8 inner tubes with TR-4 straight valve stems, designed to replace worn or punctured tubes in lawn mowers, garden tractors, golf carts, wheelbarrows, and small motorcycles.

Fitment & Compatibility

Before buying, confirm your tire size is stamped on the sidewall. These tubes fit 20x8.00-8, 20x8-8, 20x10.00-8, and 20x10-8 tires. Measure your tire’s rim diameter (8 inches) and overall diameter (20 inches). They are aftermarket, not OEM-specific, so they work across brands like John Deere, Craftsman, Toro, and Honda as long as tire dimensions match. The TR-4 straight valve stem fits standard 0.625-inch rim holes. Check that your rim doesn’t have a bent or oversized valve hole.

Key Things to Know

• Quality: Tubes are butyl rubber, decent for the price, but some users report thinner walls than premium brands. Inspect for pinholes before install.
• Installation Difficulty: Moderate. You’ll need tire irons, a compressor, and patience. Overstretching can cause tears. Use soapy water to seat the tube without pinching.
• Common Gotcha: The TR-4 stem is straight, not angled. If your rim has a deep offset, a 90-degree stem may be easier to access for inflation.
• 4-Pack Value: At ~$10 per tube, it’s economical for multiple machines, but if you only need one, a single tube from a known brand might be simpler.

Should You Buy It

If you maintain several 20-inch turf tires (mowers, carts, wheelbarrows) and want a budget-friendly bulk option, this 4-pack is a solid choice. For a single tube or a high-stress application (e.g., heavy garden tractor), consider a thicker, premium tube instead.
