Securing a bike rack to your spare tire Jeep setup demands a model that clears the tire and supports the bike weight. Finding the right bike rack for spare tire jeep can be tricky because not every rack fits every Jeep model. You need something that attaches firmly to the spare tire mount without blocking your rear view or tailgate access.
This guide will walk you through everything you need to know. We will cover the best types of racks, installation steps, and common mistakes to avoid. By the end, you will know exactly which rack works for your Jeep and how to set it up safely.
Bike Rack For Spare Tire Jeep
When you drive a Jeep with a spare tire mounted on the back, you have a unique challenge. Standard trunk or hitch racks wont work because the spare tire blocks the mounting points. A dedicated bike rack for spare tire jeep solves this by clamping directly onto the spare tire itself or its mount.
These racks are designed to handle the weight of one or two bikes while keeping them stable off-road. They also allow you to open your tailgate without removing the rack, which is a huge plus for daily use.
Why Choose A Spare Tire Bike Rack
There are several reasons to pick a spare tire mounted rack over other options:
- It keeps bikes off the roof, lowering your center of gravity
- It does not require a trailer hitch or roof crossbars
- It leaves your rear bumper clear for other accessories
- It works well with most Jeep Wrangler, Cherokee, and Gladiator models
Just keep in mind that not all spare tires are the same. Tire diameter, width, and the type of mount (factory vs aftermarket) all affect which rack will fit.
Key Features To Look For
Before you buy, check these features on any rack you consider:
- Tire size compatibility – Most racks fit tires from 29 to 37 inches. Measure your spare first.
- Weight capacity – Look for at least 60 lbs total if carrying two bikes.
- Strap or clamp design – Straps are easier to adjust, clamps are more secure.
- Tailgate clearance – The rack should not hit your tailgate when you open it.
- Anti-wobble system – This keeps the rack from shaking on bumpy trails.
Top Rack Types For Jeep Spare Tires
There are three main styles of bike racks that attach to a spare tire. Each has pros and cons depending on your needs.
Strap-On Spare Tire Racks
These are the most common and affordable option. They use heavy-duty straps that wrap around the spare tire and hook onto the rim or the tire tread. The bike frame rests on arms that extend outward from the tire.
- Easy to install and remove
- Works with most tire sizes
- Can wobble if not tightened properly
- May block your rear camera or license plate
Hitch-Mount Racks For Spare Tire
Some Jeeps have a hitch receiver behind the spare tire. In that case, you can use a standard hitch rack with an extender. This is more stable than strap-on racks but requires a hitch.
- Very stable at highway speeds
- Can carry up to 4 bikes with a platform style
- Requires a hitch extender if the spare tire is in the way
- May make tailgate access harder
Tailgate Mount Racks
These racks attach directly to the tailgate or the spare tire mount bracket. They are less common but offer a clean look. They work best for Jeeps with a factory tire carrier.
- Does not touch the tire itself
- Allows full tailgate opening
- More expensive than strap-on racks
- Limited to one or two bikes
How To Install A Bike Rack On Your Spare Tire
Installing a strap-on spare tire rack is straightforward. Follow these steps for a secure fit.
Step 1: Prepare Your Jeep
Park on level ground. Open the tailgate and inspect your spare tire. Make sure it is properly inflated and the mount is tight. Remove any covers or accessories from the tire.
Step 2: Position The Rack
Hold the rack against the center of the spare tire. The arms should point outward, away from the Jeep. Adjust the straps so they are even on both sides.
Step 3: Attach The Straps
Wrap the top strap over the tire and hook it onto the rim or tread. Do the same for the bottom strap. Pull each strap tight, but do not overtighten yet.
Step 4: Tighten Evenly
Alternate between the top and bottom straps. Pull them snug until the rack does not move when you push it. Check that the rack is centered on the tire.
Step 5: Test The Fit
Close the tailgate and check for clearance. The rack should not hit the bumper or the tailgate handle. Open and close the tailgate a few times to confirm.
Step 6: Load Your Bike
Place your bike onto the arms. Use the provided straps or bungee cords to secure the frame. Make sure the pedals and handlebars do not hit the Jeep or the ground.
Common Installation Mistakes
Even with a good rack, mistakes happen. Here are the most common ones and how to avoid them.
Not Checking Tire Pressure
A low tire can cause the rack to shift. Inflate your spare to the recommended pressure before installing the rack.
Overtightening Straps
This can damage the tire sidewall or the rim. Tighten until snug, but not so tight that the tire deforms.
Blocking The License Plate
Many racks cover the plate. Use a license plate relocator kit or a bracket that moves the plate to the side.
Ignoring Weight Limits
Exceeding the rack’s weight limit can cause it to fail. Check the manual for max capacity, and do not overload it with heavy e-bikes.
Best Practices For Off-Road Use
If you take your Jeep off-road, your bike rack faces extra stress. Follow these tips to keep your bikes safe.
- Use anti-wobble straps or rubber pads to reduce vibration
- Check all straps and bolts before every trip
- Remove the rack when not in use to prevent wear on the tire
- Consider a locking pin or cable lock to prevent theft
On rough trails, the rack will bounce more than on pavement. Slow down over bumps and avoid sharp turns with bikes loaded.
Compatibility With Different Jeep Models
Not all Jeeps have the same spare tire setup. Here is how different models handle a bike rack.
Jeep Wrangler (JK, JL, TJ)
Wranglers have a rear-mounted spare that is easy to access. Most strap-on racks fit well. For JL models with a larger 33-inch tire, check that the rack arms extend far enough.
Jeep Cherokee (KL, XJ)
Cherokees with a rear spare are less common. If yours has one, measure the tire diameter. Many racks designed for Wranglers also work on Cherokees.
Jeep Gladiator
The Gladiator has a spare tire under the bed, not on the tailgate. You cannot use a spare tire rack on this model. Instead, use a hitch rack or a bed-mounted rack.
Jeep Renegade
Renegades with a rear spare are rare. If you have one, look for a compact rack that fits smaller tires (16-18 inches).
Maintenance And Care Tips
To make your rack last, clean it regularly. Salt, mud, and road grime can rust the straps and hardware. Rinse with water after off-road trips and dry with a cloth.
Lubricate any moving parts like hinges or locking pins once a year. Use a silicone spray to keep straps from cracking. Store the rack indoors during winter if possible.
Check the straps for fraying every few months. Replace them if you see any damage. A broken strap on the highway can cause a serious accident.
Frequently Asked Questions
Can I use a bike rack for spare tire jeep with a full-size spare?
Yes, most racks are designed for full-size spares from 29 to 37 inches. Just check the product specs for your tire size.
Will the rack block my rear camera?
It can. Many racks cover the camera on JL Wranglers. You may need a camera relocator kit or a rack that offsets the bikes.
How many bikes can a spare tire rack hold?
Most hold 1 or 2 bikes. Some heavy-duty models hold 3, but that adds a lot of weight to the spare tire mount.
Do I need a hitch extender for a spare tire rack?
No, spare tire racks attach directly to the tire, not the hitch. You only need an extender if you use a hitch rack with a spare tire in the way.
Can I open my tailgate with the rack installed?
Yes, most racks allow tailgate opening. However, you may need to tilt the rack or remove the bikes first on some models.
Final Thoughts On Choosing A Rack
Picking the right bike rack for spare tire jeep comes down to your specific Jeep model and how you use it. If you drive mostly on pavement, a simple strap-on rack works fine. For off-road adventures, invest in a heavier-duty model with anti-wobble features.
Always measure your spare tire before buying. Read reviews from other Jeep owners to see how the rack performs in real conditions. With the right setup, you can carry your bikes securely and enjoy the trail without worry.
Remember to check local laws about license plate visibility and bike overhang. Some states require a flag or light if the bikes extend past the rear of the vehicle. Stay safe and happy riding.
