AR-PRO 23x10.5/9.5/8.5-12 Inner Tube Replacement With TR-13 Straight Valve Stem (2-Pack) - For Golf Cart, Tractor, John Deere Lawn Mower, Snowthrowers, Tillers, Trailers, Wheelbarrows and ATV's

What It Is

This is a 2-pack of 12-inch inner tubes (23x10.5/9.5/8.5-12) with TR-13 straight valve stems, designed to replace worn or punctured tubes in tires on lawn mowers, golf carts, tractors, snowthrowers, tillers, trailers, wheelbarrows, and ATVs.

Fitment & Compatibility

Before buying, confirm your tire size matches one of these three dimensions: 23x10.5-12, 23x9.5-12, or 23x8.5-12. The tube fits any 12-inch rim with a tire width between 8.5 and 10.5 inches. Check your current tube’s valve stem type—TR-13 is a straight, short stem (about 1.5 inches long), common on lawn tractors and small utility vehicles. If your machine requires a bent or longer valve stem (e.g., TR-218), this won’t work. Measure your tire sidewall for the exact size stamped there—don’t rely on the rim size alone. This is an aftermarket replacement, not OEM-specific, so it fits any brand that uses these dimensions (John Deere, Cub Cadet, Toro, etc.).

Key Things to Know

• Quality: AR-PRO is a solid aftermarket brand with 20k+ reviews at 4.3 stars. Tubes are butyl rubber, which holds air well and resists ozone cracking better than cheap PVC.
• Installation Difficulty: Moderate. You’ll need to break the tire bead, remove the old tube, and re-seat the tire. A tire spoon or pry bar helps; a tube of tire lube makes it easier.
• Common Gotcha: The TR-13 stem is short—if your rim has deep offset or a hubcap, the stem may not protrude enough to attach a pump. Test fit before fully mounting.
• Double Check: These are tubes for tubeless-style tires (most lawn mower tires). If your tire is marked “tubeless,” you can still use a tube—just ensure the rim has no sharp edges that could puncture the new tube.

Should You Buy It

Buy this if you have a 12-inch tire on a lawn mower, garden tractor, or small utility vehicle that needs a reliable, affordable tube replacement. It’s a solid value for the price, but skip it if your machine requires a bent valve stem or a tube for a different rim size.
