AR-PRO 4.80-12 Inner Tubes 2-Pack for 12" Tires — Heavy-Duty Butyl with TR13 Valve for Lawn Tractors & Trailers

AR-PRO 4.80-12 inner tubes are heavy-duty butyl replacements with TR13 valve stems designed to restore airtight performance to 12" utility tires.

These replacement inner tubes are built for utility equipment—lawn tractors, trailers, mowers, ATVs and more—that use 12" rims. Constructed from thicker butyl rubber and fitted with straight TR13 valve stems, the tubes prioritize puncture resistance and consistent inflation so you spend less time topping off air and more time working. The set includes two identical tubes sized to fit common 4.80-12 and 5.30-12 tire applications.

Will these inner tubes fit my lawn tractor or trailer tires?

Yes—these inner tubes are made to fit 12" rim tires with common size markings like 4.80-12 and 5.30-12. They match the internal diameter requirements for many lawn and garden tractors, utility trailers, push mowers, and similar equipment. Always check the size printed on your tire sidewall before purchasing to confirm a correct match.

• Compatible with many 12" rim tires including 4.80-12 and 5.30-12 sizes.
• Intended for lawn tractors, trailers, wagons, mowers, rototillers and similar equipment.
• Confirm tire sidewall size to ensure fitment.

How does the TR13 valve stem help with inflation and maintenance?

The tubes come with a straight rubber TR13 valve stem that provides a reliable seal and is sized for common high-pressure small-tire applications. A solid valve stem reduces the chance of air loss at the inflation point and makes connecting pumps and pressure gauges straightforward. If you maintain tire pressure regularly, the TR13 stem simplifies topping up and reduces maintenance time.

• Durable TR13 straight valve stem for secure inflation.
• Works with standard pumps and pressure gauges for small utility tires.
• Improves pressure retention compared to worn or damaged stems.

What benefits come from the thicker butyl rubber construction?

Heavier butyl rubber increases puncture resistance and extends the tube’s service life under rough or debris-prone conditions. The thicker material also helps maintain airtight performance so tires hold pressure longer between fills. While no inner tube is fully puncture-proof, robust butyl significantly lowers leak risk in demanding yard and off-road environments.

• 4X thicker butyl construction for better puncture resistance.
• Improved air retention reduces frequency of reinflation.
• Designed to endure rough surfaces common to lawn and utility use.

Any tips for swapping and installing these inner tubes?

Careful installation prevents damage and ensures a long service life. Slightly inflate the tube before seating it inside the tire to avoid twists, and avoid using sharp tools or prying metal that can tear the rubber. Check that the tire bead sits evenly around the rim and that the valve stem is straight to prevent leaks and premature wear.

• Inflate the tube slightly to remove twists before final installation.
• Do not use sharp tools when removing or installing the tube.
• Ensure tire bead is evenly seated on both rim sides and valve stem is straight.

Who is this for: This 2-pack is ideal for homeowners, landscapers, farmers and DIY mechanics who need reliable, heavy-duty replacement inner tubes for 12" utility tires. Choose AR-PRO tubes if you want improved puncture resistance, dependable air retention and a straightforward TR13 valve stem for routine inflation and maintenance.
