Atturo ST300 Trailer Tires ST225/75R15 117/112M

The Atturo ST300 tire in ST225/75R15 is a trailer tire designed to track steadily behind the tow vehicle while carrying the trailer's load. Its center rib, water channels, and interlocking tread support stable highway towing. This ST225/75R15 version has a 117/112 load index and M speed rating, so you can compare its actual rating against the vehicle's requirements.

Where It Fits

It is intended for trailer service; choose a size and load index suited to the trailer's axle, wheel, and rated load.

Features and Benefits

• Stable center rib: Helps the trailer follow the tow vehicle in a straight line.
• Water-clearing channels: Support traction on wet pavement.

Fitment and Notes

The load index indicates rated carrying capacity; a ply or load-range designation alone does not establish the tire's exact capacity. Trailer application only; verify wheel, axle, load, and speed compatibility before installation.

Why Atturo?

Atturo applies purpose-built tread design to work and towing applications, so you can choose a tire around the load and service your vehicle actually sees.
