TNCZHYLX Spare Tyre Mount Universal Carrier — 150 lb Capacity, Rust-Resistant Iron, No-Drill Install

A heavy-duty universal spare tire mount from TNCZHYLX that secures trailer, RV, and boat tires up to 150 lbs with rust-resistant iron construction and no-drill installation options.

When you need a dependable way to carry a spare wheel on trailers, campers, or boats, this universal spare tire carrier is built to hold up. It combines a reinforced triangular weld design with a rectangular rear plate and a sandblasted solid-iron finish to resist corrosion and keep the wheel locked in place. The mount accepts multiple bolt patterns and lug counts so it fits many common trailer wheels, and it installs quickly using supplied bolts—no drilling required in most setups.

What sizes and bolt patterns will this spare tire carrier fit?

The carrier is engineered for broad compatibility with trailer wheels. It fits 4-, 5- and 6-lug wheels and supports bolt patterns of 4", 4.5", 4.75", 5" and 5.5". This flexibility makes it useful for boat trailers, campers, RVs and many small utility trailers.

• Accepts 4, 5, and 6-lug wheel configurations.
• Supports major bolt circle diameters: 4", 4.5", 4.75", 5" and 5.5".
• Compatible with common trailer and RV wheel sizes.
• Works for boats, campers, utility trailers and tow vehicles.

How strong and durable is the mount under real-world conditions?

This spare tire mount has a 150 lb load rating thanks to an upgraded triangular support welded to a rectangular rear plate that secures the steel beam. The body is made from industrial-grade solid iron and finished with sandblasting to minimize surface imperfections and help prevent rust and corrosion.

• 150 lb rated capacity for most trailer spare tires.
• Triangular welded reinforcement distributes weight evenly.
• Sandblasted iron finish resists rust for longer service life.
• Hardware tightens to stop wheel wobble during travel.

How difficult is installation, and do I need special tools or drilling?

Installation is designed to be straightforward: the mount uses a sloped, bulged design to reduce wind drag and offer low ground clearance while locking the tire in place. Different-length bolts are included so you can often secure the carrier with just a wrench; in many cases no drilling is necessary. Measure your trailer rack thickness before ordering to confirm fit.

• No-drill installation typical—only a wrench required.
• Multiple bolt lengths included to fit varying rack thicknesses.
• Adjustable steel beam height to suit tire position and clearance.
• Simple removal for seasonal or storage needs.

Will this carrier protect the spare and minimize road noise or drag?

The mount’s sloping and bulging profile reduces wind resistance compared with flat-mounted alternatives, and the secure hold limits movement that can cause rattles or wear. Tightening the fasteners properly keeps the wheel stable, and the low-profile installation helps reduce added aerodynamic drag.

• Contoured shape lowers wind resistance and noise.
• Firm wheel clamp reduces rattling on rough roads.
• Low ground clearance option keeps tire tucked in.
• Powder-like sandblasted surface slows corrosion.

Who is this for: This TNCZHYLX spare tire carrier is aimed at trailer owners, RV and camper users, and boat trailer operators who need a sturdy, no-fuss way to carry a spare wheel. It’s especially useful when you want broad bolt-pattern compatibility, a heavy-duty 150 lb load rating, and a corrosion-resistant mount that installs without complex tools. Before purchase, measure the rack or bumper thickness and verify your wheel’s lug pattern to ensure the best fit.
