The 2018 Jeep Compass spare tire location is under the cargo floor, accessed by lifting the rear carpet panel. Knowing exactly where your spare is and how to use it can save you time and stress on the road. This guide covers everything you need to know about the 2018 Jeep Compass spare tire, from location to replacement options.
2018 Jeep Compass Spare Tire Location And Access
Finding the spare tire in your 2018 Compass is straightforward. Open the rear tailgate and look at the cargo area floor. You will see a large carpeted panel covering the entire back section.
Lift the panel by pulling up on the plastic handle or edge near the rear seats. Underneath, you will find the spare tire nestled in a molded foam tray. The tray also holds the jack and lug wrench.
Here is what you will see under the cargo floor:
- Spare tire (usually a compact temporary spare)
- Scissor jack
- Lug wrench
- Towing eyelet (if equipped)
To remove the spare, simply lift it straight up out of the foam tray. The tire is not bolted down, so it comes out easily. Some models may have a small retaining bolt or strap—check your owner’s manual for specifics.
If your cargo area has a subwoofer or other accessories, the spare location remains the same. The foam tray is designed to fit around these components.
What Type Of Spare Tire Comes With The 2018 Jeep Compass
The 2018 Jeep Compass typically comes with a temporary spare tire, also called a “donut.” This is a smaller, lighter tire designed for short-term use only. It allows you to drive to a repair shop but is not meant for high speeds or long distances.
Key specs of the factory spare:
- Size: Usually T125/80R17 or T135/70R18
- Maximum speed: 50 mph (80 km/h)
- Maximum distance: 50 miles (80 km)
- Pressure: 60 psi (check your sidewall)
Some trims, like the Trailhawk, may come with a full-size spare as standard. If you have a full-size spare, it will be the same size as your regular tires. Check your vehicle’s window sticker or build sheet to confirm.
If you bought a used 2018 Compass, the spare might be missing or swapped. Always verify what you have before you need it.
How To Change A Flat Tire On A 2018 Jeep Compass
Changing a flat on your Compass is simple if you follow these steps. Always prioritize safety first.
- Park on a flat, stable surface away from traffic. Engage the parking brake.
- Place wheel chocks behind the opposite wheels if available.
- Open the tailgate and lift the cargo floor panel. Remove the spare tire, jack, and lug wrench.
- Loosen the lug nuts on the flat tire slightly (about half a turn) while the tire is still on the ground. Do not remove them completely yet.
- Position the scissor jack under the vehicle’s jacking point. The jacking points are marked with notches on the pinch weld behind the front wheels and in front of the rear wheels.
- Crank the jack until it contacts the jacking point. Continue cranking until the tire is about 2 inches off the ground.
- Remove the loosened lug nuts completely. Pull the flat tire straight off the hub.
- Mount the spare tire onto the hub. Align the holes with the studs and push it on firmly.
- Hand-tighten the lug nuts in a star pattern to ensure even pressure.
- Lower the vehicle until the spare touches the ground, then tighten the lug nuts fully using the wrench. Use the same star pattern.
- Lower the vehicle completely. Remove the jack.
- Stow the flat tire and jack back under the cargo floor. Drive slowly to a tire shop.
Remember: The spare tire is temporary. Do not exceed 50 mph. Get your flat repaired or replaced as soon as possible.
2018 Jeep Compass Spare Tire Size And Specifications
Knowing the exact spare tire size for your 2018 Compass is crucial for replacement or upgrade. The factory spare size varies by trim and optional packages.
Common spare tire sizes:
- Compact temporary: T125/80R17
- Compact temporary: T135/70R18
- Full-size spare: 225/60R17 or 225/55R18 (matching regular tires)
To find your specific spare size, check the sidewall of the tire itself. Look for a string of numbers and letters like “T125/80R17.” The “T” indicates a temporary tire.
If you need to replace the spare, you can buy a matching temporary tire from a Jeep dealer or online. Prices range from $100 to $200 for a new donut. A full-size spare will cost more, typically $150 to $300 depending on brand.
Important: Do not use a temporary spare on the front axle of an all-wheel-drive (AWD) Compass for long distances. It can damage the drivetrain. If you must use it, keep it on the rear axle if possible.
Can You Use A Full-Size Spare Instead Of The Donut
Yes, you can replace the temporary spare with a full-size tire. Many owners do this for peace of mind. However, there are a few things to consider.
First, a full-size spare takes up more space under the cargo floor. The foam tray may not fit properly. You might need to remove the tray or modify it. Some owners simply place the full-size tire in the well without the tray.
Second, the weight is higher. A full-size tire and wheel weigh about 40-50 pounds, compared to 20-30 pounds for a donut. This adds weight to the vehicle, slightly affecting fuel economy.
Third, the jack and lug wrench still work fine with a full-size spare. No special tools are needed.
If you choose to upgrade, make sure the full-size spare matches the diameter of your other tires. Otherwise, it can cause issues with ABS and traction control.
Where To Buy A Replacement Spare Tire For A 2018 Jeep Compass
You have several options for buying a replacement spare tire. Here are the most common sources.
- Jeep dealership: OEM parts, but expensive. Expect to pay $150-$250 for a donut.
- Online tire retailers: Tire Rack, Discount Tire Direct, Amazon. Prices vary, often cheaper than dealers.
- Junkyards or salvage yards: Used spares from wrecked Compasses. Cheap, but inspect for damage.
- Local tire shops: They can order a matching temporary tire for you.
When buying used, check the tire’s age (look at the DOT code) and tread depth. A spare that is more than 6 years old should be replaced, even if unused. Rubber degrades over time.
Also, ensure the spare includes the correct wheel. Some spares are sold as just the tire, not mounted on a rim. You will need a compatible wheel for your Compass.
2018 Jeep Compass Spare Tire Removal And Installation Tips
Removing and installing the spare tire is straightforward, but a few tips can make it easier.
Tip 1: The spare tire is heavy. Lift with your legs, not your back. If you have a full-size spare, consider asking for help.
Tip 2: The foam tray can be fragile. When removing the spare, pull straight up to avoid breaking the tray. If the tray cracks, you can buy a replacement from a dealer or online.
Tip 3: Keep the spare tire inflated to the correct pressure. Check it every few months. A flat spare is useless in an emergency.
Tip 4: If your Compass has a subwoofer in the cargo area, the spare location is still the same. The subwoofer sits on top of the foam tray. Just lift the subwoofer out carefully to access the spare.
Tip 5: When stowing the flat tire after a change, place it in a plastic bag to keep dirt and water off the cargo carpet. This prevents stains and odors.
Common Issues With The 2018 Jeep Compass Spare Tire System
Some owners report a few common problems with the spare tire setup. Here is what to watch for.
Problem 1: The foam tray cracks or breaks over time. This is usually due to age or heavy loads. A cracked tray can still hold the spare, but it may rattle. Replacement trays cost around $50-$80.
Problem 2: The spare tire is missing when buying a used Compass. Many used cars are sold without the spare. Always check before purchase. If missing, budget for a replacement.
Problem 3: The jack or lug wrench is missing. These are often stolen or misplaced. You can buy a replacement kit from a dealer or online for about $30-$60.
Problem 4: The spare tire is the wrong size. Some previous owners may have swapped the spare without checking compatibility. Verify the size matches your vehicle’s requirements.
Problem 5: The spare tire is flat or underinflated. This is common if the tire has not been checked in years. Always inspect the spare when buying a used Compass.
