SIMEIQI 4.10/3.50-4 Inner Tubes TR-87 Bent Valve – Heavy-Duty Replacement, 2-Pack for Wheelbarrows & Hand Trucks

Overview

Meet the SIMEIQI 2-pack of 4.10/3.50-4 inner tubes, equipped with a TR-87 bent valve. These tubes are designed as a dependable, heavy-duty replacement for common small-wheeled setups, helping you get back to work quickly and confidently. The thickened rubber and robust construction support consistent performance across varying conditions, from sunlit days on asphalt to damp, uneven surfaces in the yard.

Why this matters

Instead of replacing an entire tire, a single tube swap can save time and maintenance costs. The bent valve stem makes inflation easier in tight spaces, reducing lineup friction when you’re on the move. Made from high-quality natural rubber, the tubes are built to resist aging and to maintain a reliable air seal, so your cart stays steady during use.

• TR-87 bent valve for versatile inflation access in tight spots
• Thickened rubber adds shock absorption and better contact with uneven surfaces
• Maximum inflation up to 30 PSI, suitable for light-duty wheels
• 10-inch outer diameter, designed to fit 4.10/3.50-4 wheels
• Made from natural rubber for airtightness, ductility, and durability
• 2-pack gives you ready replacements for multiple machines

The combination of reliable air retention and straightforward installation helps you keep ongoing projects moving, season after season.

What You Gain
