Cenipar 4.10/3.50-4 Inner Tubes with TR87 Bent Valve – 2-Pack for Wheelbarrows & Carts

Product overview

Upgrade your outdoor equipment with Cenipar’s 4.10/3.50-4 inner tubes, available as a convenient 2-pack. Designed for 4" rims, these tubes pair a rugged isobutylene isoprene rubber compound with a TR87 bent valve stem for easier inflation and proper seating. The result is a reliable, ready-to-use replacement option for wheelbarrows, garden carts, mowers, tractors, and similar equipment that relies on 4" tires. While no single part can guarantee flawless performance in every situation, these tubes are built to deliver steady air retention, durable wear, and smooth operation under typical outdoor use.

On a sunny workday, these tubes can help you keep projects moving. When you spot wear or a slow leak in a 4" tire, swapping in a Cenipar tube can minimize downtime and keep you productive. The two-tube pack gives you a spare on hand for seasonal maintenance or urgent repairs, helping you stay prepared without frequent trips to the store.

Installation tips

Check size before replacing: 4.10/3.50-4" tires on a 4" rim. Deflate the tire, remove the old tube, inspect bead seating, insert the new tube evenly, and inflate gradually to 30 PSI while monitoring seating to prevent pinch flats. No wheel replacement needed if the tire surface is intact.
