16x6.50-8 Tire Inner Tube Heavy Duty 16x7.50-8 Tube with TR-13 Straight Valve Stem Fit for Tractor, Garden Trailer, Golf Carts, Wheelbarrows and More (1/Pack)

What It Is

This is a heavy-duty inner tube designed to replace a punctured or worn-out tube inside a 16-inch tire with a 6.50 or 7.50-inch width. It’s commonly used in lawn tractors, garden trailers, golf carts, wheelbarrows, and other small-wheeled equipment requiring a TR-13 straight valve stem.

Fitment & Compatibility

Before buying, check these three things:

• Tire size: This tube fits tires marked 16x6.50-8 and 16x7.50-8. The “16” is the overall diameter, “6.50” or “7.50” is the width, and “-8” is the rim diameter. If your tire says 16x6.50-8 or 16x7.50-8, it’s compatible.
• Valve stem: It has a TR-13 straight valve stem (standard 0.625-inch diameter hole). Confirm your rim’s valve hole size; most lawn mower rims use this, but some older or specialty rims may require a different stem (e.g., TR-15 or TR-87 for angled stems).
• Rim width: Works with 8-inch diameter rims. No need to match the exact tire width—this tube can stretch safely between 6.50 and 7.50 widths.

Key Things to Know

• Heavy-duty construction – Thicker rubber than standard tubes, offering better puncture resistance and longer life in rough terrain or with heavy loads.
• Installation tip – Before mounting, lightly inflate the tube to round it out, then dust with baby powder or talc inside the tire to prevent pinching between the tire and rim.
• Common gotcha – Over-inflating can cause the tube to bulge or blow out at the valve stem. Stick to the tire’s recommended PSI (usually 10-20 PSI for lawn equipment).
• Valve stem alignment – When installing, make sure the stem sits straight through the rim hole. A crooked stem can leak or snap off during use.

Should You Buy It

This is a solid, affordable replacement for a standard or heavy-duty tube in 16x6.50-8 or 16x7.50-8 tires. It’s a good choice if you need a quick fix for a flat on a lawn tractor, garden trailer, or golf cart and want extra puncture resistance without paying premium prices. Not ideal for high-speed or heavy commercial use—stick to OEM tubes for that.
