AR-PRO Replacement 23x10.50-12 Tubes, Universal 23x8.50-12 23x9.50-12 Heavy-Duty Inner Tube with TR-13 Straight Valve Stems for Golf Cart, ATV, UTV, Lawn Tractor, Mowers, Garden Trailer, Snow Blowers

What It Is

This is a heavy-duty replacement inner tube designed to fit tires in the 23x10.50-12 size range, plus 23x8.50-12 and 23x9.50-12. It’s built for lawn tractors, zero-turn mowers, garden trailers, golf carts, ATVs, UTVs, and snow blowers that use 12-inch rims and require a TR-13 straight valve stem.

Fitment & Compatibility

Before buying, confirm your tire size is one of these: 23x10.50-12, 23x8.50-12, or 23x9.50-12. The tube’s 12-inch rim diameter is fixed—measure your rim’s bead seat diameter (not overall wheel diameter). Check your valve stem type: this tube uses a TR-13 straight metal stem (common on lawn/garden equipment). If your rim has a larger valve hole or requires a bent stem (e.g., some golf carts), you’ll need an adapter or a different tube. Not for tubeless-only rims or pneumatic tires with built-in sealant. Measure your tire’s actual width and height—oversized tubes can bunch and cause leaks; undersized tubes can stretch and blow out.

Key Things to Know

• Quality: Heavy-duty rubber resists punctures better than standard tubes, but it’s not puncture-proof. Use a tire liner for extra thorn/rock protection.
• Installation: Moderate difficulty—you’ll need tire irons and a bead breaker. Lubricate the tube and tire bead with soapy water to avoid pinching. Over-inflating before seating the bead can cause blowouts.
• Valve stem: TR-13 is standard for lawn tractors, but check your rim’s valve hole diameter (usually 0.625” or 0.453”). If it’s smaller, you may need a reducer or different tube.
• Common gotcha: Tubes often fit slightly loose in the tire—this is normal. If you feel a wobble after installation, re-check bead seating and tube alignment, not the tube itself.

Should You Buy It

Yes, if you need a reliable, budget-friendly replacement for a 12-inch lawn/garden tire with a straight valve stem and your tire size matches one of the three listed. Avoid it if you have an unusual rim offset, a bent stem requirement, or a tubeless tire system—this tube is built for standard, tube-type applications.
