AR-PRO 2 Packs 20×8.00-8 to 20×10.00-8 Inner Tubes

These replacement inner tubes fit a range of 8-inch rim tires from 20×8.00-8″ to 20×10.00-8″, including common mower, tractor, golf cart, and garden trailer tires. They feature TR-4 straight valve stems with rubber-covered bases and a 1.5-inch offset. The tubes are rated up to 60 psi and can fit tires listed as 20×8.00-8″, 20×10.00-8″, 19×7-8”, 18×6.50/7.50/8.50/9.50-8”. Best for users needing a flexible, multi-size tube for small to mid-sized equipment. Choose this if you operate multiple machines with 8-inch rims and want a two-pack for back-up stock. Caution: verify if your rim hole accepts the 1/2-inch bore or needs adapter to 5/8-inch rims.
Bradley Rubber Tire Tube 32″

This Bradley 32″ tube is a straightforward, heavy rubber inner tube designed for large, high-volume tires. It includes one tube and a lower-profile valve stem with a safety valve cap, which acts as a removal tool for faster deflation. Best for users needing a simple solution for larger equipment or vintage-style tires where a plain, rugged inner tube is preferred. Limitation: lacks design features beyond basic rubber construction; not specialty-rated for extreme high-pressure use.
Trans American Rubber TR-218A Inner Tube (15.5R-38)

This Trans American Rubber inner tube uses the TR-218A valve stem and is suitable for both bias and radial tires. It supports 15.5R-38 sizes and is suitable for liquid ballast operations in some agricultural and heavy equipment contexts. Best for buyers needing a robust option for larger tractors or implements that require a TR-218A valve. Limitation: ensure compatibility with your tire’s exact size and valve type before purchase.
Premium Service Farm Tractor Tire Inner Tube TR218A

This Premium Service tube is designed for heavy-duty agricultural use, compatible with radial or bias tires and made from high-quality rubber that can stretch to fit multiple sizes. Best for farmers or maintenance crews needing a durable tube that can handle demanding field conditions. Limitation: its broad compatibility may make it less optimized for very specific tire profiles; verify exact size and radial/bias compatibility for your truck or tractor.
AR-PRO Replacement 6.00-16 Heavy-Duty Inner Tubes

This AR-PRO tube fits 6.00-16 tires and similar sizes, with TR15 valve stems and wide compatibility across 16″ rim tires found on tractors, trailers, wagons, and other farm utility equipment. Best for buyers with 16-inch rims seeking a reliable, heavy-duty option. Caution: confirm your exact tire width and rim hole diameter to ensure TR15 stem clearance and proper inflation.
Buying Guide: Key Considerations for Tractor and Trailer Inner Tubes
- Rim size and tire width: Match tube size to your tire’s exact rim diameter and width. Common combinations (such as 20×8.00-8 inches) require tubes rated for those dimensions.
- Valve type and length: TR4, TR218A, and TR15 are common stems. Consider stem length and whether you need a rubber-covered base for protection or a short stem for space constraints.
- Material quality: Butyl rubber typically offers good air retention and durability for farm and utility tires. Higher-end tubes may offer greater stretch and resistance to punctures.
- Radial vs. bias compatibility: Some tubes are designed for both, but verify compatibility with your tire construction to ensure reliable seating and inflation.
- Pressure rating: Most mower and utility tubes are rated around 60 psi, while larger or heavy-duty tubes may have different limits. Do not exceed the tire’s recommended pressure.
- Application context: Home lawn care, small farms, or large agricultural settings each benefit from different tube features, such as size range, durability, and valve design.
