Trimax Spare Tire Locks

Trimax Spare Tire Locks: Purpose-Built Protection for Your Backup Wheel

A spare tire mounted on the outside of your truck, Jeep, trailer, or RV is an easy target for opportunistic theft — and losing it on the road can leave you stranded. Trimax has engineered a focused lineup of spare tire locks designed to close that vulnerability with heavy-duty hardware that's built to live outdoors in all weather conditions.

Trimax is a division of Wyers Products Group and produces more than 120 lifetime-warranted security products spanning markets such as trailer and towing, power sports, marine, RV, and bicycles — and has been in business for more than 20 years. That depth of experience in lock engineering is clearly reflected in the thoughtful design of their spare tire security solutions.

The TRIMAFLEX ST30: A Dual-Anchor Approach to Spare Tire Security

The flagship of Trimax's spare tire lineup is the ST30 TRIMAFLEX Spare Tire Cable Lock. What sets it apart from ordinary cable locks is a genuinely unique securing method: it is the only spare tire lock that secures both the tire and the tire bracket, locking through the wheel lug nut hole for maximum security — making it ideal for boat trailers, motor homes, trucks, Jeeps, vans, and more.

The ST30's construction is purpose-matched to its outdoor environment. It features a rugged 3-foot by 12mm braided steel cable system that loops around a welded frame member of the trailer or vehicle, and includes a weather-resistant cap and O-ring that help seal out dirt and corrosion. On the locking mechanism itself, a spring-loaded, 7-pin, high-security key cylinder resists drill-out attempts, and the knurled lock head is machined from 100% solid forged steel. Equally practical: there are no internal springs to seize up or break — a common failure point in locks exposed to the elements over time.

TNL740: Fast, No-Fuss Side-Mount Security

For vehicles with side-mounted spare tires, Trimax offers the TNL740 Spare Tire Nut Lock — a simpler, highly effective approach. It fits all side-mount spare tires, is also useful for securing propane tanks, provides a quick and easy solution to tire theft, and works by locking the tire nut to prevent wheel removal. This makes it an excellent option when a cable-and-bracket setup isn't practical or necessary.

Why Trimax Stands Out in Spare Tire Security

• Dual-anchor design: The ST30 is the only spare tire lock that secures both the spare tire and tire bracket to the welded frame member.
• Drill-resistant keying: A spring-loaded, 7-pin, high-security key resists attempted drill-outs and is rugged and durable — it will not bend or break.
• All-weather construction: A weatherproof cap protects against the elements, keeping the lock mechanism functional season after season.
• Broad vehicle compatibility: Both products are ideal for securing spare tires on boat trailers, motor homes, trucks, Jeeps, vans, and more.
• Lifetime warranty coverage: Trimax products are lifetime warranted, reflecting the brand's confidence in its build quality.

Whether you're hauling a boat trailer on weekends, overlanding in a Jeep, or parked long-term in an RV, Trimax's spare tire locks deliver focused, reliable protection. Explore the full range of security solutions from Trimax to find the right fit for your vehicle setup.
