Safoner RV Spare Tire Mount for Travel Trailer — 4" Aluminum Bumper Carrier, 22" Post, Triple-Lock

Safoner RV Spare Tire Mount is a heavy-duty aluminum 4" bumper carrier that securely holds standard 4-, 5-, and 6-lug spare wheels well above the bumper for reduced scraping and long-lasting outdoor use.

This trailer spare tire carrier is engineered for recreational vehicles and travel trailers that use a 4" square bumper. Constructed from thick aluminum alloy formed into three one-piece components without welded joints, the design prioritizes corrosion resistance, strength, and durability for repeated road use. The 22" vertical post raises the tire to help avoid contact with driveways and uneven terrain, while a triple-lock mounting system fights vibration to keep the wheel firmly attached during travel.

How does this mount prevent the spare tire from scraping on driveways?

The taller 22" vertical post positions the spare wheel higher than many standard carriers, giving more clearance over curbs and driveway transitions. That extra height reduces the chance the tire will drag when backing out of steep ramps or passing over dips.

• 22" vertical post for increased ground clearance
• Raises tire above bumper lip to lower scraping risk
• Useful for low driveways, steep driveways, and rough roads

Will this fit my trailer bumper and wheel bolt pattern?

The carrier is built to mount to standard 4" square rear bumpers and includes lower mounting slots for minor vertical adjustment to fit bumpers up to 4.4" tall (max width 4.3"). It accepts common 4-, 5-, and 6-lug wheels with bolt patterns between 4.0" and 5.5".

• Designed for 4" square bumper receivers
• Adjustable lower slots for bumpers up to 4.4" tall
• Compatible with 4.0"–5.5" bolt patterns (4/5/6-lug wheels)

How robust is the construction for long-term outdoor use?

Safoner uses a three one-piece formed component design made from thick aluminum alloy, avoiding welded joints that can corrode or fail over time. Aluminum provides a high strength-to-weight ratio and naturally resists rust, making this carrier suited for exterior mounting and exposure to road conditions and weather.

• Thick aluminum alloy construction for strength and corrosion resistance
• No welded seams; three one-piece formed components for durability
• Engineered for exterior use on trailers and RV bumpers

How secure is the spare when traveling on rough roads?

The triple-lock mounting design combines an anti-loosening lock washer with dual locking nuts to help resist vibration and maintain a tight fit under road conditions. This reduces the chance of gradual loosening and keeps the spare wheel stable during highway and off-highway travel.

• Triple-lock mounting: lock washer plus two nuts
• Anti-loosening features to resist vibration
• Stable rear bumper mounting for long trips

Who is this for? Owners of travel trailers, campers, and utility trailers who want a dependable external spare tire mount that raises the wheel above the bumper, fits standard 4" square bumper receivers, and works with common wheel lug patterns. This carrier is especially helpful for people who frequently encounter low driveways, rough roads, or need a corrosion-resistant, easy-to-install backup wheel holder for long-term outdoor use.
