15x6.00-6" Inner Tubes with TR87 Bent Valve Stem - Replacement Lawn Mower Tire Tubes - Suitable for Yard Tractors, Wheelbarrows, ATVs, and More (6.00-6)

What It Is

This is a 15x6.00-6" inner tube with a TR87 bent valve stem, designed to replace a flat or punctured tube in pneumatic tires on lawn tractors, wheelbarrows, ATVs, and similar small equipment. It fits inside a tire that is 15 inches tall, 6 inches wide, and fits a 6-inch rim.

Fitment & Compatibility

Before buying, verify three things:

• Tire size: Your tire sidewall must read “15x6.00-6” (or “15x6.0-6”). This tube fits that exact tire, not a 13" or 16" tire.
• Rim diameter: The rim must be 6 inches in diameter. Measure across the bead seat (where the tire sits) – not the outer lip.
• Valve stem: The TR87 is a bent (90-degree) valve stem, about 1.5 inches long. It’s common on lawn tractors with deep rims or limited clearance. If your original tube had a straight stem, this will work but the stem will angle sideways. Ensure the stem hole in the rim is at least 0.625 inches (5/8") wide.

Does not fit: Zero-turn mowers with low-profile tires (e.g., 18x6.50-8), or any tire that isn’t a 15x6.00-6. No brand-specific fit – this is universal for the size.

Key Things to Know

• Quality: Butyl rubber, standard thickness. Good for the price, but not heavy-duty. Expect 2–4 years of typical use. Avoid for commercial mowing or heavy loads.
• Installation difficulty: Moderate. You’ll need tire irons or pry bars to break the bead. Watch for pinching the tube between the tire and rim – use a little air in the tube first to prevent folds.
• Common gotcha: The bent stem can be tricky to align through the rim hole. Deflate the tube slightly, push the stem through first, then seat the tube. Over-tightening the stem nut can crack the stem base.
• Valve core: It comes with a removable valve core (for adding sealant or deflating). Keep it tight – loose cores cause slow leaks.

Should You Buy It

Yes, if you need a budget-friendly, direct replacement for a 15x6.00-6 tube on a lawn tractor or wheelbarrow and you’re comfortable with basic tire work. Skip it if you need a heavy-duty tube for rough terrain or commercial use – spend more for a thicker rubber option.
