Ever found yourself stranded with a flat tire on your trailer, only to realize your spare is nowhere in sight? Securing your spare tire is one of those simple steps that can save big headaches down the road.
Knowing how to properly attach a spare tire holder ensures your backup is always ready and easy to access. In this article, we’ll walk you through the why and how: the essentials, step-by-step instructions, and helpful tips for safe, hassle-free travel.
How to Choose and Install a Spare Tire Holder for Your Trailer
Having a spare tire ready to go is essential for every trailer owner. Whether you’re hauling cargo, equipment, or heading out on a family adventure, a flat tire can happen any time. A spare tire holder (also known as a spare tire carrier or mount) lets you keep your spare tire secure, accessible, and out of the way. But how do you choose the best spare tire holder for your trailer, and how do you install it properly? Let’s break it all down.
Understanding Trailer Spare Tire Holders
A spare tire holder is a device specially designed to mount your trailer’s spare tire securely onto the frame, tongue, or underside of the trailer. These holders come in various styles and sizes, each tailored to specific trailer designs and user preferences. Their main goal? Keep your spare tire easy to access and out of the way during transport.
Popular Types of Spare Tire Holders
When choosing a spare tire holder, it’s important to understand the main styles available. Here are some popular options:
- Bolt-On Frame or Tongue Mounts
- Attach directly to the trailer’s frame or tongue with bolts.
- Easy to install and remove.
- Compatible with most utility and boat trailers.
- Underslung (Hide-A-Spare) Carriers
- Mount under the trailer bed or frame.
- Keeps the tire hidden and out of the way.
- Often favored for RVs and large enclosed trailers.
- Clamp-On Holders
- Secure to an angle-iron or railing without drilling.
- Adjustable and portable.
- Great for temporary or adjustable setups.
- Bumper Mounts
- Attach to the rear bumper of a trailer or RV.
- Suitable mostly for square steel bumpers.
- Sidewall or Back-Mounted Holders
- Affix to vertical surfaces or gates.
- Sometimes lockable for extra security.
How to Choose the Right Spare Tire Holder
1. Check Compatibility
- Tire Size: Not all holders fit all tire sizes. Check your trailer’s rim diameter and bolt pattern (e.g., 5-lug, 6-lug).
- Trailer Construction: Identify your trailer’s frame type—some mounts fit only box frames, while others fit angle-iron or C-channel.
- Weight Rating: Make sure the holder is rated to support the weight of your spare tire.
2. Decide on Placement
Consider these locations:
- Tongue: Good for utility trailers; keeps the spare up front.
- Side/Back Frame: Frees up tongue space; easy rear access.
- Under-Frame: Hidden and neat, but may be harder to reach.
- Bumper: Convenient on RVs and campers with steel bumpers.
3. Assess Security Needs
- Locking Features: If theft is a concern, choose models with locking lugs or the ability to add a padlock.
4. Installation Simplicity
- No-Drill Options: Clamp-on mounts are ideal if you want to avoid drilling holes.
- Bolt-On Styles: More permanent but may require drilling.
5. Material and Durability
- Coating: Look for powder-coated or galvanized steel to resist rust and corrosion.
- Build Quality: Thicker, well-finished steel provides durability.
Step-by-Step: How to Install a Trailer Spare Tire Holder
Here’s a general guide for installing a bolt-on or clamp-on spare tire holder. Adjust the steps as needed for your specific carrier and trailer.
What You’ll Need
- The spare tire carrier (holder)
- The spare tire and appropriate lug nuts
- Wrench or socket set (size depends on your hardware)
- Drill (possibly, for bolt-on holders)
- Tape measure
- Level (optional, for aesthetic placement)
- Rust-inhibiting spray or touch-up paint (if drilling)
Installation Steps

-
Test Fit the Mount
- Hold the spare tire and mount up to the chosen spot.
- Mark the mounting holes with a pencil or marker.
-
Prepare to Attach
- For bolt-on: Position the mount and mark drill points.
- For clamp-on: Loosen clamps to fit around the frame or railing.
-
Drill Holes (If Needed)
- Carefully drill pilot holes at the marked points.
- Apply rust inhibitor or paint to the holes to prevent corrosion.
-
Attach the Mount
- Secure the mount to the frame using the provided hardware.
- For bolt-on: Use washers and lock nuts for extra security.
- For clamp-on: Tighten clamps evenly to prevent shifting.
-
Mount the Spare Tire
- Lift the spare onto the holder, aligning the lug holes.
- Insert mounting studs or lug bolts, and tighten securely.
-
Check Security
- Wiggle the tire—there should be no play.
- Double-check all bolts for tightness.
-
Test Access
- Practice removing and reinstalling the tire to make sure you can do it easily, even in an emergency.
Benefits of Using a Spare Tire Holder
Why not just toss the spare in your cargo area or truck bed? Using a proper holder offers several clear advantages:
- Space Efficiency: Frees up valuable cargo room for your gear.
- Protection: Keeps the spare off the ground, away from road debris and damage.
- Quick Access: You won’t need to unload the trailer to reach your spare.
- Safety: Prevents the tire from moving around and becoming a hazard.
- Security: Many holders can accommodate locks to deter theft.
Common Challenges and How To Overcome Them
While installing a spare tire holder is usually straightforward, you might encounter a few hiccups:
- Mismatched Bolt Patterns: Double-check your trailer’s and spare tire’s patterns for compatibility.
- Rust or Corrosion: On older trailers, it may be tougher to find solid, rust-free spots.
- Limited Mounting Locations: Some trailers offer little access or flat space for mounting. Undermount or clamp-on holders can be a solution.
- Interference with Trailer Features: Avoid blocking tail lights, license plates, doors, or ramps.
- Vibration Loosening Bolts: Use lock washers, thread locker, or nylon-insert lock nuts.
Practical Tips & Best Practices
- Regularly Check Tightness: Vibrations can loosen bolts—check them every couple of trips.
- Carry Proper Tools: Keep a lug wrench and jack in your emergency kit.
- Weatherproofing: Touch up any scratched or drilled areas with rust-resistant paint.
- Off-Season Maintenance: Remove and inspect the holder annually for rust or damage.
- Balance: Position the spare to avoid unbalancing your trailer or tongue weight.
Cost-Saving Tips for Your Spare Tire Holder
- Comparison Shop: Prices for spare tire holders range from around $15 to over $80 depending on features and build. Comparing prices at big box stores, trailer dealers, and specialty suppliers can yield savings.
- Look for Bundles: Some retailers offer combos with both the mount and wheel/tire for less.
- Shipping Costs: Bulky steel holders may carry extra shipping fees. Whenever possible, buy locally or look for free shipping offers.
- DIY Installation: Dealers may offer installation, but most holders can be self-installed if you’re handy—saving labor costs.
- Watch for Promotions: Retailers often discount trailer accessories before peak camping or travel seasons.
Summary
A well-chosen spare tire holder is a small upgrade that brings big peace of mind. It keeps your trailer’s spare tire secure, accessible, and off the ground, so you’re always ready for the unexpected. Matching your trailer, tire, holder type, and mounting location are crucial for a safe and hassle-free setup. With the right preparation and occasional maintenance, your holder will last for years and could save your trip from an untimely flat.
Frequently Asked Questions (FAQs)
1. Will any spare tire holder fit my trailer?
Not necessarily. You must check both your trailer frame type and the tire/rim bolt pattern. Always verify compatibility before buying.
2. Is drilling into the trailer frame necessary to install a spare tire holder?
Many holders require bolting and may need you to drill holes. However, clamp-on models can be installed without drilling, ideal for those wanting a less permanent solution.
3. Can I mount a spare tire holder underneath my trailer?
Absolutely! Underslung or hide-a-spare carriers are designed for this purpose. Just ensure there’s enough clearance and that you can access the tire when needed.
4. How do I prevent my spare tire from being stolen?
Choose a mount that offers locking features. You can use a wheel lock, locking lug nut, or a padlock to secure the spare.
5. What if my trailer has an aluminum frame?
You’ll need to use compatible hardware to avoid corrosion (such as stainless steel) and may want to use a clamp-on holder instead of drilling, as aluminum frames can be more vulnerable and may void warranties if drilled improperly.
With a few smart choices and proper installation, your trailer’s spare tire will always be ready when you need it most. Safe travels!
