Trimax spare tyre cable lock 36" x 12mm Black/Chrome — welded-loop braided steel, weatherproof

The TRIMAX ST30 spare tire cable lock is a heavy-duty 36-inch, 12mm braided steel security cable that locks both your spare tire and its mounting bracket to deter theft.

Whether you tow boats, drive a motorhome, run a work van or own a Jeep, the ST30 was engineered to protect the full spare assembly — not just the tire — with a welded loop cable and a weatherproof locking cap. Built for outdoors use, this lock combines a thick braided steel cable, a bracket-encompassing routing design, and a sealed lock head so the mechanism keeps working in rain, salt air, and road grime.

How does the ST30 secure both the spare tire and the mounting bracket?

The ST30’s design routes the cable around the spare tire and through or around the bracket mounting points so the lock immobilizes the entire assembly. This prevents thieves from simply unbolting or lifting the spare off its mount.

• 12mm braided steel cable resists cutting and sawing attempts.
• Welded cable loops form a continuous, high-strength connection.
• Routing method includes both tire and bracket for full coverage.
• Lock head secures the cable ends together to prevent quick-release theft.

Will this fit my vehicle or trailer?

The 36-inch cable length and flexible braided construction make the ST30 compatible with most common spare tire locations on trailers, motorhomes, trucks, vans, and SUVs. Its looped end and adjustable routing accommodate a wide range of bracket styles and frame positions.

• 36" length works with rear and underbody spare mounts.
• 12mm cable diameter offers heavy-duty strength for larger vehicles.
• Flexible cable suits tight or angled routing around frames.
• Designed for boats, trailers, RVs, trucks, Jeeps and commercial vans.

How does the ST30 hold up outdoors and in harsh conditions?

The lock uses a weather-proof cap over the locking mechanism to keep out water, dirt, and salt, preserving function and resisting corrosion. The cable’s durable finish and welded construction are built for repeated outdoor exposure.

• Weather-proof cap protects the internal lock parts from moisture.
• Chrome and black finish reduces surface corrosion and wear.
• Welded joints maintain strength after repeated use and exposure.
• Materials chosen for marine and road-salt environments.

How difficult is it to install and use the TRIMAX ST30?

Installation is straightforward and requires no special tools beyond the vehicle’s existing spare mount access. Feed the cable around the tire and bracket, insert the ends into the lock body, and secure with the key; removal is the reverse process.

• Simple feed-and-lock operation for quick installation.
• Works with existing spare mounting hardware — no modifications needed.
• Comes with keys for straightforward locking and unlocking.
• Flexible cable eases routing in tight spaces beneath vehicles.

Who is this for: The TRIMAX ST30 is aimed at vehicle owners who carry an exposed spare and want stronger protection than a simple lug-nut lock — especially boat owners, RV and trailer users, off-roaders, fleet operators, and anyone parking in public or remote areas. If you need a robust, weather-resistant cable that secures both the tire and its mounting bracket, the ST30 offers a practical combination of length, thickness, and a sealed lock head designed for outdoor use.
