Jeep Gladiator Spare Tire Mount: Best Options for Off-Roading
Reading Time: 8 minutes Owning a Jeep Gladiator is about more than just driving; it’s about adventure, off-roading, and being ready for anything. One often overlooked but critical part of this readiness is your spare tire mount. If you’ve ever been stuck with a flat tire miles away from help, you know why having a secure, accessible spare matters. Many Gladiator owners, especially beginners, are unsure about the best way to carry, mount, and protect their spare tire. This guide explains everything you need to know, in simple words, to make confident choices about your Jeep Gladiator spare tire mount.
Why The Spare Tire Mount Matters
The spare tire mount does more than hold a tire. It affects safety, storage space, and even how your Gladiator looks and handles. Here’s why it should be on your checklist:
- Quick access in emergencies: You need your spare fast during a flat.
- Protects your tire: Mounts keep your spare safe from damage.
- Saves space: A good mount stops the spare from taking up cargo room.
- Legal requirement: Many states require your spare to be properly secured.
One thing many new owners miss: a poor-quality or badly placed mount can loosen over time, risking your spare falling off during a drive or off-road trip.
Types Of Jeep Gladiator Spare Tire Mounts
Choosing the right mount starts with knowing your options. Not all mounts fit every need or tire size.
| Mount Type | Location | Best For | Pros | Cons |
|---|---|---|---|---|
| Factory (Underbody) | Under the bed | Daily driving | Hidden, frees up space | Hard to access, limits tire size |
| Bed Mount | Truck bed | Oversized tires, off-roading | Easy access, fits big tires | Loses cargo space |
| Tailgate Mount | On or near tailgate | Quick swaps, stylish look | Convenient, shows off spare | Adds rear weight, may block camera |
| Bumper Mount | Rear bumper | Heavy-duty, rock crawling | Very strong, no bed space lost | Expensive, may affect approach angle |
| Interior Mount | Cabin/behind seats | Show vehicles, city use | Safe from theft, weather | Reduces passenger/cargo space |
Pro tip: If you upgrade to a larger tire size, the factory underbody mount often won’t fit. Many beginners only find this out after buying new wheels.

Factors To Consider When Choosing A Spare Tire Mount
Picking a mount isn’t just about looks. Here’s what really matters for Gladiator owners:
- Tire Size Compatibility
- Measure your spare’s diameter and width.
- Most factory mounts fit up to 33-inch tires. For 35-inch or larger, you’ll need an aftermarket solution.
- Mounting Location
- Underbody mounts are discreet but hard to reach.
- Bed and tailgate mounts offer easy access but take up space.
- Ease of Installation
- Some mounts bolt on with basic tools.
- Others require drilling or professional help.
- Weight Rating
- Check the mount’s rated capacity. Oversized tires are heavier.
- Example: 37-inch tires can weigh 70–90 lbs with the wheel.
- Security
- Look for mounts with locking systems to prevent theft.
- Not all mounts include a lock—check before buying.
- Build Quality
- Powder-coated steel resists rust and lasts longer.
- Cheap mounts may fail on rough trails.
- Price
- Budget mounts start around $100; heavy-duty options can be $500+.
- Don’t sacrifice safety for cost.
- Legal Compliance
- Your spare must not block taillights or license plates.
Non-obvious insight: Vibration is a silent killer. Some mounts vibrate loose on rough roads. Always check for rubber isolators or anti-vibration features.

How To Install A Jeep Gladiator Spare Tire Mount
Installing a spare tire mount can be simple or complex, depending on the type. Here’s a general step-by-step for a basic bolt-on bed mount:
- Gather Tools
- You’ll need a socket wrench, torque wrench, and safety gloves.
- Check Parts
- Lay out all mount pieces and bolts. Check the instructions.
- Locate Position
- Place the mount where you want it in the bed. Check for clearance.
- Mark and Drill (if needed)
- Mark where bolts go. Some mounts require drilling; others use existing holes.
- Bolt in Place
- Secure the base with bolts. Tighten to the recommended torque.
- Attach Tire Carrier
- Fix the carrier arm or plate. Test for movement.
- Mount the Spare Tire
- Lift the tire onto the mount. Bolt it down tightly.
- Double-Check Security
- Shake the tire. There should be zero movement.
Example: Installing a DV8 Offroad bed mount usually takes about 30–60 minutes for a beginner, with no special skills needed.
Common mistake: Forgetting to re-torque bolts after the first 100 miles. Vibrations can loosen hardware.
Maintenance And Safety Tips
Even strong mounts need care. Here’s how to keep your setup safe and long-lasting:
- Inspect monthly: Look for rust, cracks, or loose bolts.
- Check after off-roading: Rough trails can loosen mounts.
- Clean regularly: Remove dirt and debris to prevent rust.
- Lubricate locks: If your mount has a lock, spray it with lubricant to prevent sticking.
- Replace worn parts: Don’t wait for failure—replace rusted or bent components immediately.
Unexpected insight: Salt and mud can corrode steel fast. If you live in a snowy or coastal area, rinse the mount after each trip.
Real-world Example: Upgrading From Factory To Bed Mount
Let’s say you upgraded your Gladiator’s tires to 35-inch all-terrains. The factory underbody mount won’t fit. Here’s what you might do:
- Buy an ACE Engineering bed mount (fits up to 40-inch tires).
- Install using basic tools in one hour.
- Lose about 10% of your bed cargo space but gain easy access and peace of mind.
- Add a locking lug nut for theft protection.
Many Gladiator owners report that bed mounts reduce the time to change a tire from 20 minutes (factory) to under 10 minutes (bed mount), which is critical during bad weather or off-roading.
Spare Tire Mount And Off-roading
If you go off-road, your choice of mount is even more important:
- Tailgate and bumper mounts are popular for off-roaders, as they keep the tire easy to reach.
- Bed mounts prevent underbody damage on rocks or deep ruts.
- Factory underbody mounts can drag or get damaged on tough trails.
Practical tip: Always check your mount after every trail run. Off-roading vibrations can loosen even the best hardware.
How A Spare Tire Mount Affects Your Jeep Gladiator
A spare tire mount isn’t just an accessory—it changes how your Gladiator works:
- Weight distribution: A heavy tire on the tailgate or bumper can change handling.
- Fuel economy: Extra weight can drop MPG by 1–2 miles, especially with large tires.
- Rear visibility: Tailgate and bumper mounts may block your camera or view.
- Appearance: Some mounts add a rugged, custom look.
What many miss: Insurance and warranty terms may change if you use a non-factory mount. Check with your dealer before making big changes.
