Carrying bikes on a Jeep with a spare tire requires a rack designed to fit around that rear mount. A jeep spare tire bike rack is the smartest way to transport your bikes without blocking your tailgate or adding extra weight to your hitch. This guide covers everything you need to know to choose, install, and use the right rack for your Jeep.
You don’t want a rack that wobbles, scratches your paint, or makes it hard to open the back. The right setup lets you load up and hit the trail fast. Let’s break down the options, features, and installation steps so you can get riding sooner.
Jeep Spare Tire Bike Rack
This type of rack mounts directly onto your spare tire carrier. It uses straps or brackets to secure the rack to the tire itself. Most models hold two to three bikes, depending on the design and your tire size.
The main advantage is that it keeps your hitch free for towing. It also keeps bikes high off the ground, away from mud and rocks. But not every rack fits every Jeep. You need to check your tire diameter, wheel offset, and tailgate clearance.
How A Spare Tire Bike Rack Works
The rack attaches to the spare tire using adjustable arms and straps. These arms hook around the top and bottom of the tire. The rack then extends outward to hold the bike frames.
Most racks have padded cradles that protect your bike’s paint. They also include straps to secure the bikes in place. Some models have a tilting feature that lets you access the rear cargo area without removing the bikes.
Benefits Over Other Rack Types
- No hitch required – frees up your receiver for other gear
- Keeps bikes visible and secure behind the vehicle
- Easy to install and remove without tools
- Works with most Jeep models including Wrangler, Cherokee, and Gladiator
- Does not block rear lights or license plate when bikes are loaded
Key Features To Look For
Not all racks are built the same. Some are flimsy, others are rock solid. Here are the features that matter most when choosing a jeep spare tire bike rack.
Tire Size Compatibility
Your spare tire diameter is the first thing to check. Most racks fit tires from 29 to 37 inches. If you have a larger tire, look for an extender kit. Smaller tires may require a different mounting system.
Also check the tire width. A skinny spare might not provide enough surface area for the rack’s arms to grip. Measure your tire’s sidewall width and compare it to the rack’s spec sheet.
Weight Capacity
Each rack has a maximum load rating. Most can carry 60 to 100 pounds total. That means two mountain bikes or three lighter road bikes. Exceeding the limit can cause the rack to bend or the spare tire carrier to fail.
Consider the weight of your bikes. A downhill bike can weigh 35 pounds. Two of those plus the rack itself might push the limit. Always add up the total weight before loading.
Tailgate Access
Some racks block the tailgate handle or prevent it from opening fully. Look for a model that tilts away from the vehicle. This lets you open the rear door without removing the bikes.
Other racks have a quick-release mechanism. You undo a few straps and the whole rack swings to the side. This is very handy when you need to grab gear from the back.
Anti-Wobble Design
A wobbly rack is annoying and dangerous. The best racks use multiple contact points to lock onto the tire. Some have rubber pads that grip the tread. Others use metal brackets that bolt to the wheel studs.
Look for racks with adjustable tension straps. These let you tighten the rack against the tire until it feels solid. A good rack should not move at all when you shake it.
Installation Steps
Installing a jeep spare tire bike rack is usually straightforward. Most models come with clear instructions. Here is a general step-by-step process that applies to many popular brands.
- Clean the spare tire surface. Remove any mud or debris so the straps grip well.
- Position the rack against the tire. Align the top arms with the upper tread and the bottom arms with the lower tread.
- Hook the top arms over the tire. Pull them tight so they sit firmly against the rubber.
- Attach the bottom arms. These usually have a strap that goes around the bottom of the tire.
- Tighten all straps evenly. Work from top to bottom, checking that the rack is centered.
- Test the rack by shaking it. If it moves, tighten the straps more. If it still moves, adjust the arm positions.
- Load your bikes onto the rack. Secure each bike with the provided straps or bungees.
- Check clearance. Make sure the bikes do not hit the rear window or tailgate when you open it.
Some racks require you to remove the spare tire first. This is common with models that bolt to the wheel hub. Follow the manufacturer’s instructions carefully to avoid damaging your Jeep.
Tools You Might Need
- Socket wrench for bolt-on models
- Torque wrench to tighten bolts to spec
- Measuring tape to check tire diameter
- Level to ensure the rack sits straight
Top Brands And Models
Several companies make reliable spare tire bike racks. Here are the most popular ones that Jeep owners trust.

Yakima offers a similar design with a few extra features. Their rack has a built-in lock to secure the bikes. It also includes a hitch adapter if you want to use it on a different vehicle.
The Yakima rack fits tires from 29 to 37 inches. It holds two bikes and has a weight limit of 75 pounds. The straps are easy to adjust and do not loosen over time.

Allen Sports makes a budget-friendly option. Their rack is lighter and simpler than the premium brands. It holds two bikes and has a weight capacity of 60 pounds.
The Allen rack uses a single strap system. It is quick to install but may wobble more than higher-end models. It is a good choice if you only carry bikes occasionally.

Common Problems And Solutions
Even the best jeep spare tire bike rack can have issues. Here are the most common problems and how to fix them.
Rack Wobbles At High Speed
If the rack shakes on the highway, the straps are not tight enough. Stop and retighten them. Also check that the arms are properly seated on the tire tread.
Some racks have a secondary strap that goes around the wheel. Use it for extra stability. If the wobble persists, consider adding a stabilizer bracket that bolts to the wheel studs.
Bikes Hit Each Other
When you load two bikes, the handlebars and pedals can touch. This can scratch the frames. Use frame protectors or foam pads between the bikes.
Also adjust the bike positions. Alternate the direction of the handlebars. One bike facing left, the other facing right. This creates more space between them.
Tailgate Won’t Open
Some racks block the tailgate handle. If your rack does not tilt, you may need to remove the bikes to open the back. Look for a rack with a tilt feature if this is a deal breaker.
Another option is to install a tailgate hinge extension. This moves the spare tire outward, giving more clearance for the rack. It is a simple mod that many Jeep owners use.
Spare Tire Carrier Sags
Over time, the spare tire carrier can sag under the weight of the rack and bikes. This is more common on older Jeeps. Reinforce the carrier with a heavy-duty bracket or replace it with a stronger unit.
Some aftermarket carriers are rated for higher loads. They use thicker steel and better hinges. Upgrading the carrier is a permanent solution to sagging.
Tips For Safe Driving With A Rack
Driving with bikes on the back changes your vehicle’s handling. Here are some tips to stay safe.
- Check the rack before every trip. Tighten straps and bolts.
- Do not exceed the rack’s weight limit. Overloading can cause failure.
- Drive slower on bumpy roads. The rack and bikes add stress to the spare tire mount.
- Use a flag or light on the bikes if they extend past the vehicle width.
- Remove the rack when not in use. It adds drag and reduces fuel economy.
Also be aware of your rear visibility. The rack and bikes can block your view. Use your side mirrors more often. Some states require a rearview camera or additional mirrors if the cargo blocks the rear window.
Maintenance And Care
A little maintenance keeps your rack working for years. Here is what to do.
- Clean the rack after muddy trips. Dirt can cause rust and wear out straps.
- Lubricate moving parts like hinges and tilt mechanisms. Use a silicone spray.
- Inspect straps for fraying. Replace them if they show signs of wear.
- Check bolts and screws for tightness. Vibration can loosen them over time.
- Store the rack indoors when not in use. UV rays can degrade plastic parts.
If you live in a snowy area, wash the rack after driving on salted roads. Salt accelerates corrosion. A quick rinse with a hose prevents damage.
Frequently Asked Questions
Will a spare tire bike rack work on any Jeep?
Most racks fit Wranglers, Cherokees, and Gladiators. But you need to check your spare tire size and carrier strength. Some models like the Renegade have a different mounting system.
Can I use a spare tire rack with a lifted Jeep?
Yes, as long as the spare tire is the same size as the other tires. Lifted Jeeps often have larger tires. Make sure the rack is rated for that diameter.
How many bikes can I carry on a spare tire rack?
Most racks hold two bikes. Some three-bike models exist but they are heavier and may overload the carrier. Stick with two for safety.
Do I need to remove the spare tire to install the rack?
It depends on the model. Strap-on racks do not require removal. Bolt-on racks that attach to the wheel hub do require taking the tire off first.
Is a spare tire rack better than a hitch rack?
It depends on your needs. Spare tire racks keep the hitch free for towing. Hitch racks are more stable and easier to access the tailgate. Choose based on what you tow and how often you use the rear door.
Final Thoughts
A jeep spare tire bike rack is a practical solution for carrying bikes without a hitch. It mounts securely to your spare tire and keeps your bikes out of the way. Just make sure to check your tire size, weight limits, and tailgate clearance before buying.
Installation is simple with basic tools. Most racks come with everything you need. Take your time to adjust the straps and test the fit. A properly installed rack will not wobble or damage your Jeep.
