These AR-PRO butyl inner tubes are heavy-duty replacement tubes for 21x11-8 and compatible tires, supplied as a 2-pack with straight TR6 metal valve stems for reliable inflation and puncture resistance.

Replace worn or leaking inner tubes with a rugged option built for ATVs, lawn tractors, garden trailers, golf carts, snow blowers and other small utility equipment. Each tube is molded from thick butyl rubber for airtight performance and fitted with a TR6 metal valve stem that holds pressure securely under demanding use. The 2-pack gives you a spare for faster maintenance and less downtime on the trail, job site, or property.

Will these inner tubes fit my ATV, lawn tractor, or garden trailer?

Yes — the AR-PRO tubes are designed to work across a range of common small-tire sizes. They are sized to fit 21x11-8 and 22x11-8 listings and will often work with similar diameter/width tires listed as 22x10-8, 21x10-8, 20x11-9 and other close dimensions. Always confirm your tire’s published size before ordering.

• Primary fit: 21x11-8 and 22x11-8 tires
• Also compatible with nearby sizes like 22x10-8, 21x10-8, 20x11-9
• Works in equipment such as ATVs, garden trailers, wagons, lawn mowers, and some Gator models
• Sold as a two-pack so you have a spare for quick replacement

How durable are these butyl rubber tubes for rough use?

AR-PRO inner tubes use a thicker butyl compound to improve puncture resistance and reduce air loss over time. That thicker wall construction withstands rough surfaces better than thin general-purpose tubes, and the butyl material helps maintain an airtight seal so you need to inflate less often. They’re intended for frequent outdoor use where durability matters.

• 4X thicker butyl construction for improved puncture resistance
• Good airtight performance to minimize reinflation
• Suitable for rough terrain and utility applications

What does the TR6 metal valve stem mean for inflation and service?

The straight TR6 metal valve stem provides a more secure connection than some rubber-stem alternatives and is better suited to higher-pressure or heavier-load applications. Metal stems resist collapse and cracking, making them easier to use with air compressors and gauges. They also help ensure a reliable seal so your tire pressure stays consistent during operation.

• TR6 straight metal valve stem for secure inflation
• Compatible with standard air compressors and pressure gauges
• Reduced risk of valve failure compared with soft rubber stems

Are there tips for installing and maintaining these tubes?

Install carefully to avoid pinching or twisting the tube. Slightly inflate the tube before seating it in the tire, ensure the tire bead is even on both sides of the rim, and avoid sharp tools during installation. Regularly check pressure and inspect for foreign objects that can cause punctures.

• Slightly inflate tube before fitting to prevent twisting
• Seat tire bead evenly on both sides of the rim
• Avoid sharp tools and use rim-safe installation methods
• Keep a spare (this product is a 2-pack) for quick roadside repairs

Who this is for: These AR-PRO inner tubes are made for owners and operators of small utility vehicles and equipment — from ATV riders and landscapers to homeowners with garden trailers, lawn tractors, wagons, or snow blowers. If you need a durable, airtight replacement tube with a reliable metal valve stem and a spare on hand, this 2-pack is a practical, cost-effective choice.
