Key Features – Bridgestone TR4 Tube

Exact Size Matching: Made specifically for 130/90-16, 325/100/90-19, and 80/100-21 tires. No guessing. No poor fit. Strong TR4 Metal Valve Stem: The straight metal valve stays firm under vibration and makes air filling easy. Quality Butyl Rubber Build: Thick, flexible rubber helps reduce slow air leaks and holds pressure longer. Stable Air Retention: Keeps tire pressure consistent for better balance and smoother rides. Handles Road Heat Well: Designed to perform during long highway rides without losing strength. Ideal for Spoke Wheels: Perfect for motorcycles that require tube-type tires. Easy to Install: Flexible material helps reduce pinching during mounting. Trusted Brand Manufacturing: Made by Bridgestone, a well-known name in motorcycle tire technology. Balanced Thickness: Strong enough for durability, flexible enough for proper seating inside the tire. Built for Everyday Riding: Suitable for street, touring, and light off-road use.

Fitment Clarity – Choose the Right Size

Correct tube sizing matters. Here’s how these options are typically used:

130/90-16 – Common for cruiser and touring rear wheels
325/100/90-19 – Often used on classic and dual-purpose front wheels
80/100-21 – Common on off-road and dual-sport front wheels

Always match the tube size to the tire sidewall marking. If your tire reads 80/100-21, choose the same tube size. Do not guess. Oversized tubes can crease. Undersized tubes can overstretch.

Installation Insight from Real-World Experience

When installing a Bridgestone TR4 Tube, add a small amount of air before placing it inside the tire. This helps the tube hold its shape and prevents twisting. Use tire lubricant to reduce pinch risk during mounting. After installation:

Inflate slowly
Check bead seating
Verify valve alignment

These simple steps extend tube life and improve ride safety.

Who This Is For

This tube is ideal for:

Riders using tube-type tires
Off-road and dual-sport riders
Cruiser owners with classic spoke wheels
Anyone replacing an aging or punctured tube

If you ride long distances, uneven roads, or mixed terrain, a trusted inner tube is not optional—it’s essential.
