It supports spare tires up to 35 inches in diameter and features a dual-layer stabilization design with rubber isolators to reduce movement and noise. Best for owners needing a highly adaptable, universal fit with vibration reduction. Limitation: installation may require precise alignment for non-standard crossbars.

Buying Guide
What should you consider before buying a truck spare tire rack?
Weight capacity, tire size compatibility, and mounting method are primary considerations. Check that your roof crossbars or rear frame can support the extra load. For longer trips or off-road use, look for vibration reduction features and anti-theft locking mechanisms. If you operate a fleet or multiple vehicle types, choose adjustable or universal-fit racks for flexibility.
Will this mount on my vehicle’s roof or undercarriage?
Roof-mounted carriers require compatible crossbars and rail spacing. Some models are designed for universal crossbars (1″–3″ thickness), while others target trailer or rear-frame mounting. Always verify mounting points and the vehicle’s roof capacity with the manufacturer’s guidelines.
Which features improve security and reduce noise?
Anti-theft locks and magnetic bases deter theft and accidental release. Dual-layer vibration control with rubber isolators minimizes road noise and movement, improving stability on rugged roads. Self-locking screws or chains add theft deterrence on semi-truck installations.
What are common limitations to expect?
Some racks require precise alignment or additional adapters for non-standard crossbars. Drilling is sometimes avoided but may be needed for certain installations. Large tires (near 35 inches) can add substantial weight, affecting fuel economy and handling. Always confirm compatibility with your vehicle and tires before purchase.
Maintenance and safety tips
- Regularly inspect locks, screws, and mounting brackets for corrosion or wear.
- Keep rubber isolators clean to maintain vibration reduction performance.
- Re-torque mounting hardware after the first few trips and periodically thereafter.
- Use the provided security hardware when parking in high-theft areas.
