AR-PRO Inner Tube 6-12 (6.00-12) TR13 Offset Straight Valve Stem — 2-Pack Butyl Rubber

The AR-PRO 6-12 (6.00-12) inner tube with a TR13 offset straight valve stem is a heavy-duty replacement tube designed to restore reliable inflation and smooth rolling for lawn tractors, trailers, golf carts, and utility vehicles.

Built from resilient butyl rubber and shaped for both radial and bias ply 6-12 tires, this two-pack of inner tubes combines a rugged construction with a user-friendly TR13 straight valve stem. It fits a wide range of small vehicle wheels — from zero-turn mowers to compact trailers — and is intended to deliver steady air retention, resistance to pinching, and straightforward installation when you need to replace worn or damaged tubes.

How will this inner tube improve my lawn tractor or trailer ride?

Replacing an old or cracked tube with the AR-PRO 6-12 restores correct tire pressure and helps the tire maintain its intended shape under load. The butyl compound reduces slow leaks and stands up to repeated inflation cycles, which improves stability and reduces bounce over uneven ground.

• Butyl rubber resists air permeation for longer inflation retention.
• Proper pressure keeps tire contact patch consistent for better traction.
• Designed tolerance minimizes pinch flats during mounting and use.

Is the TR13 offset straight valve stem compatible with my wheel?

The included TR13 valve stem is a straight, rubber-mounted stem with a small offset that fits common 6-12 wheel valve holes. It is suitable for standard wheels used on lawn equipment and utility trailers; ensure your rim opening accepts a rubber-mounted TR13 for proper fit and sealing.

• TR13 valve type matches many small vehicle rims and tires.
• Rubber base allows a tight, vibration-resistant seal.
• Offset stem offers easier access when mounted on some rims.

Which tires and vehicles are compatible with this tube?

This tube fits 6-12 (6.00-12) sized tires and is engineered to work with both radial and bias ply constructions. Typical applications include lawn tractors, zero-turn mowers, golf carts, trailers, and small utility vehicles where a reliable replacement inner tube is required.

• Works with 6R12 radial and 6.00R12 bias ply tires.
• Commonly used on lawn tractors, garden trailers, and golf carts.
• Also suitable for some ATVs, UTVs, and sub-compact tractors where size matches.

How do I install and maintain these inner tubes for best life?

Installation is straightforward with basic tools: remove the tire from the rim, inspect for sharp objects, slightly inflate the tube to shape it, seat it inside the tire, and then remount the tire before fully inflating to the recommended pressure. Regular inspection and keeping debris-free rims and tires will extend tube life.

• Check tire interior and rim strip for nails, rust, or burrs before mounting.
• Inflate slowly to recommended PSI and avoid overinflation.
• Store spare tubes in a cool, dry place away from direct sunlight and oils.

Who is this product for? Owners of lawn tractors, utility trailers, golf carts, zero-turn mowers, and other small vehicles looking for a durable, easy-to-install replacement inner tube will find the AR-PRO 6-12 a practical choice. It suits DIYers who perform their own tire maintenance as well as service shops that need a reliable two-pack for routine repairs and fleet upkeep.
