The Extreme Max 5001.5837 Heavy-Duty Offset Spare Tire Carrier is a versatile, side-mount carrier designed for use on trailer frames up to 3.5" wide x 4" tall.

Finished with a sleek, black powder coat, the heavy-duty carrier features a steel construction that provides excellent strength and protects against rust and other damage, keeping your trailer looking great. The carrier fits most four and five-lug 12", 13", 14" and 15" spare tires. Includes two M12 x 1.75 x 45 studs.
