GICOOL 23x8.5/9.5/10.5-12 Butyl Inner Tubes, 2 Pack with TR13 Valve Stem, Heavy-Duty Inner Tubes, Replacement Tubes for John Deere Garden Tractor, Lawn Tractor, Riding Mower, MTD Rider

What It Is

This is a 2-pack of heavy-duty butyl inner tubes (23x8.5/9.5/10.5-12) with TR13 valve stems, designed to replace worn or punctured tubes in riding mowers, lawn tractors, and garden tractors—commonly used on John Deere, MTD, and similar models.

Fitment & Compatibility

Before buying, confirm your tire size is listed as 23x8.5-12, 23x9.5-12, or 23x10.5-12. This tube fits any of these widths because it’s a single size that stretches to accommodate the range. Check your existing tire sidewall for the exact marking. Ensure your rim is 12 inches in diameter. The TR13 valve stem is a standard straight metal stem (approx 1.5" long) that fits most 12" rims—verify your rim’s valve hole is not recessed or angled, as that may require a different stem type. This is an aftermarket part, not OEM, but it’s a direct replacement for most John Deere, MTD, Cub Cadet, Husqvarna, and similar lawn tractor tubes.

Key Things to Know

• Quality: Butyl rubber holds air longer than standard rubber, resists dry rot, and handles moderate punctures better. The 2-pack is cost-effective if you’re doing both rear tires.
• Installation difficulty: Moderate. You’ll need tire irons, a bead breaker, and some patience. Watch for pinching the tube between the tire and rim—use baby powder or soapy water on the tube to reduce friction.
• Common gotcha: The TR13 stem is straight, not angled. On some mowers with tight clearance between the rim and axle, a 90° stem is easier to access for inflation. Measure your clearance before buying.
• Sizing note: If your tire is exactly 23x10.5-12, this tube will fit, but it will be stretched to its limit—consider a slightly larger tube (e.g., 24x12-12) for a looser fit and less stress on the rubber.

Should You Buy It

Buy this if you need a reliable, affordable replacement for a standard 12" lawn tractor tube and don’t mind doing the swap yourself. It’s a solid value for the price and works well on most John Deere, MTD, and similar riders. Skip it if you need an angled valve stem or have an odd-size rim.
