AR-PRO MR14/15 Inner Tubes 2-Pack, Heavy-Duty Butyl with TR13 Straight Valve Stems, Puncture-Resistant

Whether you run a mower, trailer, wagon, wheelbarrow, snow blower or small utility cart, the right inner tube keeps equipment rolling. These AR-PRO tubes are molded from thicker butyl rubber and fitted with TR13 straight valve stems to suit a wide range of R14 and R15 tire sizes. The design prioritizes puncture resistance, airtightness and simple installation so you spend less time repairing flats and more time working.

Which tires and equipment will these inner tubes fit?

These tubes are sized MR14/MR15 and compatible with many common 14" and 15" tire dimensions used on lawn and utility equipment. They are not automotive passenger car tubes—use them for mowers, trailers, wagons, wheelbarrows, small tractors and similar gear.

• Fits MR14/MR15 and 14"–15" tire size ranges listed (e.g., 265/60R14, 275/60R15, 235/75R15).
• Works with lawn mowers, garden tractors, wagons, snow blowers, wheelbarrows and yard trailers.
• Ideal when replacing worn or damaged inner tubes on small equipment rims.

How durable and puncture-resistant are these tubes?

AR-PRO inner tubes use a thicker butyl rubber compound to improve resistance to punctures and slow leaks compared with thin, economy tubes. The extra material adds robustness where tires encounter debris, gravel and garden tools.

• 4X thicker butyl rubber construction for increased durability.
• Improved airtight retention reduces frequent reinflation.
• Better suited to rough terrain and utility work than lightweight alternatives.

What valve type and inflation details should I know?

Each tube comes with a TR13 straight valve stem, a common choice for small equipment requiring reliable, high-pressure inflation. The straight stem simplifies pump access and pairs with standard caps and inflators compatible with TR13 fittings.

• Equipped with TR-13 straight valve stems for secure inflation.
• Compatible with common hand pumps and compressors using TR13 fittings.
• Inflate slightly during installation to avoid twisting; ensure bead seating before full inflation.

How do I install these inner tubes without causing damage?

Proper installation minimizes the risk of pinches or valve damage. Avoid using sharp tools, work the tube gently into the tire, and inflate gradually while checking bead alignment on the rim.

• Do not use sharp implements when replacing the tube.
• Partially inflate the tube to prevent twisting during placement.
• Make sure the tire bead sits evenly on both rim sides before final inflation.

Who is this for: The AR-PRO MR14/15 2-pack is made for homeowners, landscapers and small-fleet operators who need reliable, longer-lasting inner tubes for 14" and 15" lawn and utility tires. Choose these tubes when you want a straightforward replacement that resists punctures, holds air longer and uses a common TR13 valve stem for easy inflation—especially useful for mowers, garden tractors, wagons, wheelbarrows and small trailers.
