2-Pcs 16x6.50-8 Tube 16x7.50-8 Inner Tube 16x650-8 16x750-8 Tube | Bent Valve Stem for Lawn Mowers / Snow Blowers / ATVs / Go Kart and More

What It Is

This is a two-pack of 16x6.50-8 and 16x7.50-8 inner tubes with a bent valve stem, designed to replace worn or punctured tubes in lawn mowers, snow blowers, ATVs, and go karts that use 8-inch rims with tire widths between 6.50 and 7.50 inches.

Fitment & Compatibility

• Tire sizes: Fits 16x6.50-8 and 16x7.50-8 tires. The tube’s 8-inch diameter matches the rim size—do not use on 7- or 9-inch rims.
• Valve stem: Bent stem (90-degree) is common on mowers and ATVs with limited clearance; straight-stem machines may need an adapter or different tube.
• Brand/model: Not OEM-specific. Works with most brands (Toro, John Deere, Craftsman, Husqvarna, etc.) that use these tire sizes. Check your current tire’s sidewall for exact size.
• Measurements: Tire width (6.50 or 7.50) is a range—tube will stretch. Verify rim width is 4.5–5.5 inches for proper fit.
• Before buying: Remove the wheel and inspect the old tube’s valve stem type and location. Measure tire height (16 inches) and rim diameter (8 inches) to confirm.

Key Things to Know

• Quality: Basic rubber tube—adequate for light-duty mowing/snow blowing. Not heavy-duty; may not hold up to sharp debris or high-speed ATV use.
• Installation difficulty: Moderate. Requires removing the wheel, breaking the tire bead, and careful tube insertion to avoid pinching. A tire spoon or pry bars are needed.
• Common gotchas: Bent valve stem can be tricky to align through the rim hole. Over-inflating (over 30 PSI) can cause blowouts. Under-inflating risks pinch flats.
• Valve stem length: Stem is about 1.5 inches—may be too short for deep rims or fender clearance. Check clearance before mounting.

Should You Buy It

Buy this if you need a quick, budget-friendly replacement for a standard 16x6.50-8 or 16x7.50-8 tube on a lawn mower or snow blower, and you’re comfortable with basic tire work. Skip it if you need heavy-duty ATV performance, a straight valve stem, or a tube for a different rim size—look for a thicker, size-specific option.
