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

Safoner Trailer Spare Tire Holder is a heavy-duty, tilt-forward aluminum carrier that mounts to 4" RV bumpers to secure a spare tire while preserving storage access and improving ground clearance.

This aluminum spare tire carrier is built for RV and trailer use where durability, road vibration resistance, and easy access to rear storage matter. Constructed from three one-piece formed aluminum components with no welded joints, the unit resists corrosion and flex while lifting the tire higher above the bumper. The tilt-forward design allows you to open rear cargo doors without first removing the spare, and the triple-lock mounting system helps keep the tire in place on long trips.

How does the design protect my RV rear cargo access?

The carrier tilts forward so the spare tire clears the trailer’s rear door or cargo opening, letting you reach storage without unbolting the wheel. The mechanism is simple to operate and keeps the tire secure when returned to the locked position.

• Tilt-forward hinge for unobstructed cargo door movement
• No need to remove the spare to access rear storage
• High vertical post keeps tire away from door swing path

Will this fit my 4" RV bumper and wheel bolt pattern?

Yes — the Safoner carrier is made for standard 4" square rear bumpers and includes adjustable mounting slots to fit up to a 4.4" tall bumper (maximum width 4.3"). It accepts common wheel lug patterns so most trailer and RV spare wheels mount directly.

• Compatible with 4" square bumpers and bumpers up to 4.4" tall
• Works with 4-, 5-, and 6-lug wheels
• Accepts bolt patterns from 4.0" to 5.5" for broad wheel compatibility

How does the carrier handle road vibration and rough driving?

The carrier’s thick aluminum alloy construction and three one-piece formed components eliminate welded seams that can fatigue under vibration. A triple-lock mounting strategy — dual nuts plus an anti-loosening lock washer — reduces the chance of hardware backing off on bumpy roads.

• One-piece formed aluminum components for strength and fatigue resistance
• Heavy-duty triple-lock mounting system prevents loosening
• Taller 22" vertical post raises the tire to reduce scraping and impacts

What clearance and ground protection does the taller post provide?

The 22" vertical post positions the spare farther above the bumper so the tire is less likely to contact driveways, dips, and obstacles. That extra height helps prevent scraping and reduces the risk of tire damage when negotiating uneven surfaces.

• 22" post increases distance between tire and bumper/ground
• Improved clearance for driveways, dips, and uneven terrain
• Less chance of tire scuffing or impact against obstacles

Who is this for: This carrier suits RV and trailer owners who need a rugged, corrosion-resistant spare tire mount that preserves rear cargo access and increases ground clearance. It’s ideal for travelers with 4" square bumpers who want wide wheel compatibility (4–6 lug, 4.0"–5.5" bolt patterns) and a vibration-resistant mount for frequent road use.
