Mounting a spare tire bike rack for jeep requires the right adapter to clear the rear-mounted spare. A spare tire bike rack for jeep is one of the smartest ways to carry your bikes without blocking your tailgate or adding a hitch. If you own a Jeep Wrangler, Cherokee, or any model with a spare on the back, this rack solves the “where do I put the bikes” problem fast.
You do not need to drill holes or remove your spare tire permanently. Most racks clamp directly onto the spare or use a bracket that fits between the spare and the carrier. This keeps your Jeep looking clean while letting you haul one, two, or even three bikes on long trips.
But not every rack works with every Jeep. You have to check the tire size, the offset, and whether the rack clears the tailgate handle. This guide walks you through everything—from choosing the right rack to installing it in under 30 minutes.
Why Choose A Spare Tire Bike Rack For Jeep
Hitch racks are great, but they block your rear camera and make it harder to open the tailgate. Roof racks require you to lift heavy bikes overhead. A spare tire mount puts the bikes right where you can see them and access them easily.
Another big plus: you keep your hitch free for a cargo carrier or a trailer. If you camp or haul gear, that extra hitch space matters. Plus, the weight sits low and centered, so your Jeep handles better than with a roof load.
Most racks also fold down or tilt away so you can open the tailgate without removing the bikes. That is a huge convenience when you need to grab a cooler or a bag from the back.
Key Benefits At A Glance
- No hitch needed—frees up your receiver for other accessories
- Easy access to tailgate with tilt or fold features
- Keeps bikes stable and secure on rough trails
- Works with most Jeep models that have a rear-mounted spare
- Simple install with basic hand tools
How To Pick The Right Spare Tire Bike Rack For Jeep
Before you buy, measure your spare tire. The rack needs to fit the tire diameter and width. Most racks work with tires from 29 to 35 inches, but some only fit stock sizes. Check the specs on the product page carefully.
You also need to look at the offset. Some spare tires stick out far from the tailgate. If your spare is aftermarket or has a deep offset, you might need an adapter plate to bring the rack closer to the tire. Without it, the rack will wobble or hit the tailgate handle.
Weight capacity is another big factor. A single bike rack usually holds up to 50 pounds. A two-bike rack can hold 80 to 100 pounds total. If you have heavy e-bikes or fat-tire bikes, look for a heavy-duty model with reinforced arms.
Compatibility Checklist
- Measure your spare tire diameter and width
- Check the offset of your spare tire
- Confirm the rack fits your Jeep model and year
- Verify the weight limit for your bikes
- Look for a tilt or fold feature for tailgate access
Top Spare Tire Bike Rack For Jeep Models
There are several brands that make reliable racks. The most popular ones include the Smittybilt, Rugged Ridge, and the Yakima SpareTime. Each has its own strengths, so pick based on your needs.
The Smittybilt SRC is a solid choice for Wranglers. It bolts directly to the spare tire carrier and holds two bikes. It has a tilt-down feature so you can open the tailgate. The build is all steel, so it is heavy but very durable.
Rugged Ridge makes a similar rack that fits both JK and JL models. It uses a clamp system that grips the spare tire. The arms fold up when not in use, which keeps the rack out of the way. It is a bit lighter than the Smittybilt but still strong.
Yakima SpareTime is a premium option. It works with most Jeeps and has a quick-release mechanism. The rack tilts away from the tailgate without tools. It is more expensive, but the build quality and ease of use are top-notch.

Installation Guide For Spare Tire Bike Rack For Jeep
Installing a spare tire bike rack for jeep is straightforward. You do not need a mechanic. Just a socket set, a wrench, and about 30 minutes. Here is the step-by-step process.
First, remove the spare tire cover if you have one. Some racks clamp directly to the tire, so the cover needs to come off. If your rack uses a bracket that goes behind the tire, you can leave the cover on.
Next, position the rack on the spare tire. Most racks have adjustable arms that wrap around the tire. Tighten the straps or bolts evenly so the rack sits centered. Do not overtighten—you can damage the tire sidewall.
If your rack uses a bracket that bolts to the spare tire carrier, remove the lug nuts and slide the bracket in place. Then reinstall the lug nuts and tighten to the manufacturer’s torque spec. This method is more secure but takes a few extra minutes.
Once the rack is mounted, attach the bike arms. These are the parts that hold the bike frame. Adjust them to fit your bike’s geometry. Most arms have foam pads to protect the frame. Make sure the pads are clean and dry before loading the bike.
Finally, test the tilt feature. If your rack tilts, make sure it clears the tailgate handle and the rear window. If it hits, you may need an adapter to space the rack out or in.
Tools You Will Need
- Socket set with metric and standard sizes
- Torque wrench (if using bracket mount)
- Allen wrenches (usually included with rack)
- Measuring tape
- Level (optional but helpful)
Common Problems And Fixes
One common issue is the rack hitting the tailgate handle. This happens when the spare tire is too close to the body. A simple fix is to use a spacer or adapter that moves the rack forward. You can buy these adapters online for about $20.
Another problem is wobbling. If the rack shakes while driving, check the straps or bolts. They may have loosened during the first few miles. Retighten them and add a drop of thread locker to the bolts. Also, make sure the bike is centered on the rack. An off-center load will wobble more.
Some users report that the rack blocks the rear license plate. This is illegal in many states. You can buy a license plate relocation kit that moves the plate to the spare tire or the rack itself. It is a cheap and easy fix.
Adapter Plates And Why You Might Need One
If your spare tire has a deep offset, the rack will sit too far from the tailgate. This makes the rack unstable and can cause the bikes to hit the rear window. An adapter plate brings the rack closer to the tire, reducing leverage and improving stability.
Adapter plates are usually made of steel and bolt between the spare and the carrier. They add about 1 to 2 inches of clearance. Some racks come with an adapter included, but many do not. Check the product description before buying.
If you have a lifted Jeep with oversized tires, an adapter is almost always needed. The larger tire pushes the rack further out, which increases the lever arm. Without an adapter, the rack will flex and may damage the spare carrier.
Spare Tire Bike Rack For Jeep And Tailgate Access
One of the best features of these racks is the ability to open the tailgate without removing the bikes. Most racks have a tilt mechanism that swings the bikes away from the tailgate. This is essential for daily use.
There are two types of tilt mechanisms: manual and spring-assisted. Manual tilts require you to pull a pin and push the rack forward. Spring-assisted tilts use a gas strut to lift the rack automatically. Spring-assisted is easier but more expensive.
Some racks also have a fold-down feature. Instead of tilting, the arms fold down so you can open the tailgate. This works well if you have limited space behind the Jeep. However, fold-down racks usually require you to remove the bikes first.
Test the tilt or fold mechanism before you load the bikes. Make sure it moves freely and does not bind. If it sticks, lubricate the pivot points with silicone spray.
Weight Distribution And Driving Safety
When you load bikes on a spare tire rack, the weight sits behind the rear axle. This can affect your Jeep’s handling, especially on rough roads. Keep the load as light as possible. Do not exceed the rack’s weight limit.
If you carry two heavy bikes, the rear end may sag. This can reduce traction on the front wheels. If you notice sagging, consider adding air springs or a weight distribution hitch. These are not common on Jeeps, but they help if you haul heavy loads often.
Also, check your tire pressure. A heavy load on the spare tire rack can put extra stress on the spare tire carrier. Make sure the spare is properly inflated and the carrier bolts are tight. Loose carriers can cause the spare to wobble, which makes the rack unstable.
Maintenance Tips For Your Rack
Spare tire racks are exposed to mud, salt, and sun. Clean the rack regularly with soap and water. Pay attention to the pivot points and straps. Dirt and grit can cause premature wear.
Lubricate the tilt mechanism every few months. Use a dry lubricant like silicone spray. Avoid oil-based lubes because they attract dirt. Also, check the straps for fraying. Replace them if you see any damage.
If your rack has foam pads, replace them when they crack or harden. Old foam can scratch your bike frame. You can buy replacement pads online for a few dollars.
Winter Storage
If you live in a cold climate, remove the rack during winter if you do not use it. Salt and snow can cause rust. Store the rack in a dry place. If you leave it on, rinse it with fresh water after driving on salted roads.
Some racks have plastic parts that become brittle in cold weather. Do not force the tilt mechanism if it feels stiff. Warm it up with a heat gun or wait for the temperature to rise.
