HIAORS Inner Tubes 145/70-6 (145x70-6, 4.50-6) Pack of 2 with Bent Metal Valve Stem — Durable Replacement for Lawn Mowers & ATVs

HIAORS 145/70-6 inner tubes are a two-pack of replacement rubber tubes with bent valve stems engineered to fit 145x70-6, 4.50-6 and 5.30-6 utility tires for mowers, go-karts and small ATVs.

When a puncture or slow leak puts a utility tire out of service, swapping in a properly sized inner tube gets equipment back to work quickly. These replacement tubes match common 6-inch wheel sizes used on lawn tractors, garden carts, mini bikes and compact utility equipment. Each tube includes a pre-mounted bent metal valve stem to make inflation easier in confined rims and to reduce valve stem stress during use.

Will these inner tubes fit my 145x70-6 or 4.50-6 tire?

Yes — the HIAORS tubes are sized to replace inner tubes for tires labeled 145/70-6, 145x70-6, 4.50-6, 5.30-6 and equivalent 13x5.00-6 applications. Verify the tire sidewall markings before ordering to ensure compatibility. If your wheel has a 6-inch diameter and lists one of these size codes, this tube will be a suitable match.

• Fits: 145/70-6, 145x70-6, 4.50-6, 5.30-6, 13x5.00-6
• Designed for rims with a 6" diameter
• Check tire sidewall size and rim type before installation

How does the bent metal valve stem help installation and use?

The pre-attached bent valve stem is angled to make pumping easier when the wheel well or rim pocket limits straight access. Its metal construction resists bending and wear, which reduces the chances of valve damage during mounting and use. That angle also positions the valve for convenient tire pressure checks without removing the wheel in many applications.

• Bent valve simplifies inflation in tight wheel wells
• Metal stem offers improved durability over rubber-only stems
• Reduces valve stress during mounting and operation

What equipment can these tubes be used on?

These inner tubes serve a broad range of light-duty vehicles and tools that use 6-inch wheels. They work well in outdoor power equipment, small trailers and recreational vehicles where the listed tire sizes are common. Because they come in a two-pack, you can carry a spare or replace both front or rear tubes when doing maintenance.

• Lawn mowers, garden tractors and riding mowers
• Wheelbarrows, hand trucks, garden carts and utility wagons
• ATVs, go-karts, mini bikes, pressure washers and generators

How do I install and care for these replacement tubes?

Installing an inner tube requires removing the tire from the rim, inspecting and cleaning the wheel interior, then seating the tube and inflating to the recommended pressure. Avoid pinching the tube during installation and ensure the valve stem is properly aligned and tightened. Regularly check tire pressure and inspect for embedded debris that could cause new punctures.

• Deflate and unseat tire carefully to avoid pinches
• Inspect wheel for sharp edges, debris or corrosion
• Inflate to manufacturer-recommended pressure and test for leaks

Who this is for: This 2-pack from HIAORS is aimed at homeowners, landscapers and hobbyists who maintain small equipment with 6-inch wheels — anyone who needs an affordable, ready-to-install spare for lawn mowers, utility carts, go-karts, mini bikes or compact ATVs. It’s also useful for fleet managers and repair shops that service a variety of light-duty machines and want dependable replacement tubes with easier valve access.
