BKBNSJ 2-Pack 19x7-8 Inner Tubes with TR13 Valve – Heavy-Duty Fit for Mowers, Tractors & Golf Carts

Overview

The BKBNSJ 2-pack inner tubes are designed for common 19x7-8 sizing, compatible with a range of outdoor power equipment such as mowers, tractors, golf carts, and snow blowers. With two tubes in the box, you can swap in a spare quickly and get back to work or play without extended downtime.

Whether you’re maintaining a tidy lawn, navigating rugged fields, or clearing a path in winter, these tubes provide a reliable option to keep wheels turning smoothly. The universal fit covers several sub-sizes (19x7-8, 19x7.00-8, 20x7-8), so you can confirm compatibility before purchasing for peace of mind.

Durability and material performance

Constructed from high-quality butyl rubber, the inner tubes offer strong permeability control and resistance to aging and inorganic acids. They’re built to endure temperature swings, helping maintain performance under varied seasonal conditions.

• High-quality butyl rubber with good permeability control
• Resistance to aging and temperature variations
• Compatibility with a broad range of equipment (mower, tractor, golf cart, snow blower and more)
• Includes 2 tubes for quick replacement

Installation, testing, and care

Installing a spare tube is straightforward. Before you seal it in, test the new tube for leaks by submerging it in water—any visible bubbles indicate a defect and should be replaced. If you encounter an issue, contact us for a fast replacement.

• Two inner tubes included for easy swaps
• Before installation, submerge in water to check for leaks

Performance on the go

By reducing the friction between the tire and hardware, the inner tubes can lessen wheel vibration and extraneous noise, contributing to a steadier, more controlled ride. The TR13 straight valve stem design supports reliable inflation and helps keep air pressure steady over time.

Efficient air retention coupled with a robust valve design means less frequent reinflation, so you can focus on the task at hand rather than tire maintenance. Always verify your exact model to ensure the best fit, and store spares in a cool, dry place when not in use.
