AR-PRO Tire Inner Tube MR14/15 — 14"/15" TR13 Valve, 4X Thicker Butyl (1-Pack)

AR-PRO MR14/15 heavy-duty butyl inner tube with a TR13 straight valve stem — built to replace and reinforce R14 and R15 equipment tires for garden, yard and utility use.

This single-pack inner tube by AR-PRO is engineered as a direct-replacement solution for a wide range of lawn, garden and light utility tires sized for 14" and 15" rims. Constructed from thicker butyl rubber and fitted with a TR13 straight valve stem, the tube aims to keep air sealed under higher pressures and resist punctures while you work, tow or transport equipment.

Will this inner tube fit my R14 or R15 tire?

The AR-PRO MR14/15 tube is sized to accommodate many common R14 and R15 equipment tire measurements. Check the tire markings or your original tube model to confirm compatibility before purchase.

• Compatible sizes include MR14/15 plus common tire marks such as 265/60R14, 275/60R14 and multiple 15" variants.
• Designed for lawn mowers, garden tractors, wagons, trailers, wheelbarrows and similar utility tires.
• Compare rim diameter and cross-section numbers to ensure a correct match.

How durable and puncture-resistant is the butyl construction?

AR-PRO uses a reinforced butyl rubber formulation that is thicker than standard inner tubes to reduce the frequency of flats and slow leaks. While no tube is invulnerable, the heavier rubber improves abrasion resistance and maintains an airtight seal to minimize reinflation needs.

• 4X thicker butyl rubber for enhanced abrasion and puncture resistance.
• Airtight performance lowers routine top-offs compared with thinner tubes.
• Suitable for rugged surfaces encountered in yard work and light off-road use.

What are the valve specifications and inflation considerations?

The tube comes with a TR13 straight valve stem, a common valve type for equipment tires that supports secure inflation and compatibility with most pump connectors. Inflate the tube carefully when fitting to avoid twisting or seating errors.

• Equipped with a TR-13 straight valve for standard pump and compressor fittings.
• Partially inflate before seating the tire bead to prevent pinching or twisting.
• Follow tire manufacturer pressure recommendations; do not overinflate.

Are there installation tips or special precautions?

Proper installation helps extend tube life and prevents damage. Use soft tools and avoid sharp objects; inspect the tire and rim for debris or sharp edges before installation.

• Do not use sharp metal tools when replacing the inner tube.
• Inflate slightly during installation to ensure correct bead seating on both sides of the rim.
• Check rim strip and tire interior for objects that could puncture the new tube.

Who is this for: The AR-PRO MR14/15 inner tube is ideal for homeowners, landscapers, and small-fleet operators who need a reliable replacement tube for lawn mowers, garden tractors, trailers, wagons, wheelbarrows, golf carts and snow blowers riding on 14" or 15" rims. Choose this tube if you want a thicker butyl option with a standard TR13 valve for higher air retention and fewer roadside interruptions. If you rely on your equipment for regular yard work or towing light loads over mixed terrain, this AR-PRO tube provides a straightforward, durable replacement to keep your fleet moving.
