Dutton-Lainson Spare Tire Carriers

Dutton-Lainson Spare Tire Carriers: Built for the Trailer Life

When you're hauling a boat to the lake or towing a utility trailer across rough terrain, a flat tire is never just an inconvenience — it's a trip-ending problem. That's why having a reliable spare tire carrier mounted to your trailer is essential, and few names carry more credibility in this space than Dutton-Lainson. Founded in 1886, the company has grown into a leading manufacturer of quality products for marine, agricultural, industrial, and automotive markets. Their spare tire carriers reflect that same long-standing commitment to function and durability.

What Sets Dutton-Lainson Spare Tire Carriers Apart

Dutton-Lainson's spare tire carriers are engineered specifically for trailer applications — particularly boat trailers — where clearance, corrosion resistance, and secure mounting are non-negotiable. Several design features distinguish these carriers from generic alternatives:

• TUFFPLATE® Zinc Finish: Dutton-Lainson's spare tire carriers feature a zinc-plated TUFFPLATE® finish , providing robust corrosion resistance that holds up in wet marine environments and harsh outdoor conditions.
• Extra Offset Design: The heavy-duty carrier extends the spare tire at an angle to avoid damage or marring of boat finish, fitting wheel sizes from 13" to 15" with trailer tongues up to 3" x 5".
• Wide Rim Compatibility: Newly added length allows handling of extra-wide tires or spanning wider tongues of custom-built trailers, and carriers fit either 4 or 5 hole rims.
• U-Bolt Style Mounting: The U-bolt style bracket includes extra length to allow handling of wide tires and to fit wide tongues. This design provides a secure, rattle-free connection to a variety of trailer frame profiles, including I-beam styles.
• Lock-Ready Options: Certain models include a U-bolt style carrier with a lock bracket — just add your own padlock for theft protection. This is especially valuable at busy boat launch parking areas where spare tire theft is a known risk.
• Made in the USA: Dutton-Lainson spare tire carriers are made in the USA , backed by a manufacturer with over a century of American manufacturing expertise.

Choosing the Right Dutton-Lainson Carrier for Your Trailer

Certain models extend the spare tire up and away from the trailer and boat, with heavy-duty steel construction fitting wheel sizes from 9 to 14 inches and trailer tongues up to 3 x 5 inches. For larger wheels or wider frames, the Extra Offset model (DL22145) is a popular choice: it can handle 15" wheels and fits a variety of trailer frame sizes , making it a versatile solution for everything from bass boats to RV trailers. Meanwhile, the standard U-bolt models like the 6220 series offer a cost-effective, fit for 8", 9", or 12" wheels with 4 or 5-hole rims and a zinc TUFFPLATE finish.

With Dutton-Lainson being the last domestic manufacturer left for several major product lines, you can count on the company to do things the right way. Whether you're outfitting a simple utility trailer or a serious boat rig, Dutton-Lainson spare tire carriers deliver the dependability that comes from generations of American craftsmanship.
