AR-PRO 2-Pack Inner Tubes 20x8-8 to 20x10-8 with TR-4 Valve

Overview

Discover AR-PRO’s 2-pack inner tubes, designed for common 8-inch rims and a tire width range from 8 to 10 inches. These tubes are a versatile option for several small-vehicle setups, offering a ready replacement when you need to minimize downtime in the yard or workshop. With two tubes per package, you’ll have a spare on hand for nearby projects or seasonal setups.

Universal fit and valve design

Each tube uses a TR-4 straight valve stem, a standard choice for many universal inner tubes used with lawn equipment and utility vehicles. The valve is rubber-coated and positioned with a 1.5-inch offset from the tube center, helping alignment during installation and inflating consistently as you top off air.

The 60 psi maximum rating gives you a practical range for typical outdoor equipment while maintaining a robust feel for demanding tasks. The valve length, at about 1.38 inches, is compatible with common rim holes of 1/2 inch and can be adapted for up to 5/8 inch with a B6 rim bushing if needed.

Compatibility and real-world use

These inner tubes fit tires labeled 20x8.00-8" through 20x10.00-8" on 8-inch rims. They also cover related sizes like 19x7-8" and 18x6.5-8" variants, making them a flexible choice for a range of equipment from riding movers to light utility trailers. This universal fit is ideal when you’re stocking spare parts for multiple machines, or when you’re matching replacements for different tires over time.

Real-life use cases include mowing, tilling, light landscaping work, snow clearing, and occasional garden hauling. The tubes are designed to maintain an airtight seal if punctured, helping to minimize operation interruptions during busy seasons.
