Custom spare tire covers protect your Wrangler’s rear-mounted spare from UV damage. A Jeep Wrangler spare tire cover is more than just an accessory—it’s a shield for your tire and a style statement for your rig. Whether you daily drive your Jeep or take it off-road every weekend, the right cover keeps your spare looking fresh and your Jeep looking sharp.
You might think any cover will do, but that’s not true. The wrong one can fade, crack, or even trap moisture against your tire. This article walks you through everything you need to know: materials, sizing, installation, and maintenance. Let’s get your spare tire covered the right way.
Why You Need A Jeep Wrangler Spare Tire Cover
Your spare tire sits on the rear gate, exposed to sun, rain, mud, and road grime. Without a cover, the rubber degrades faster. UV rays cause dry rot and cracking. Dirt and moisture accelerate wear. A cover also protects the tire from theft and minor scrapes.
Beyond protection, a cover adds personality. You can choose a solid color, a camouflage pattern, or a design that shows off your Jeep’s name or a favorite brand. It’s a low-cost way to customize your rig.
Key Benefits At A Glance
- Blocks UV rays that cause cracking and fading
- Keeps dirt, mud, and road salt off the tire surface
- Reduces the risk of tire theft (some covers lock)
- Adds a custom look to your Jeep’s rear end
- Prevents the spare from rattling against the gate
Jeep Wrangler Spare Tire Cover
Now let’s talk about the specific options for your Wrangler. The market is full of covers for different models and years. You’ll find covers for the JK, JL, TJ, and YJ generations. Each has a slightly different spare tire mount and tire size.
Most covers are made from vinyl, polyester, or neoprene. Vinyl is waterproof and easy to clean but can crack in extreme cold. Polyester is breathable and resists fading. Neoprene is stretchy and snug but can trap moisture if not vented.
Material Comparison Table
| Material | Pros | Cons |
|---|---|---|
| Vinyl | Waterproof, cheap, easy to wipe clean | Can crack in cold, not breathable |
| Polyester | Breathable, UV-resistant, lightweight | Not fully waterproof, may fade over time |
| Neoprene | Stretchy, snug fit, good insulation | Can trap moisture, pricier |
Your choice depends on your climate and how you use your Jeep. If you live in a rainy area, go with a breathable polyester cover to prevent moisture buildup. If you’re in a dry, sunny place, vinyl works fine.
How To Choose The Right Size
Getting the size wrong is the most common mistake. A cover that’s too loose will flap in the wind and may blow off. One that’s too tight can stretch out or damage the tire’s sidewall. You need to measure your spare tire’s diameter and width.
Here’s how to measure:
- Check the tire’s sidewall for numbers like 33×12.50R17. The first number is the diameter in inches (33). The second is the width (12.50).
- If you don’t see the numbers, use a tape measure. Measure from the ground to the top of the tire (diameter) and across the tread (width).
- Compare your measurements to the cover’s size chart. Most covers list a range, like “fits 31-33 inch tires.”
Common sizes for Wranglers:
- Stock tires (30-31 inches): Look for a cover labeled 30-31
- 33-inch tires: Covers for 32-34 inches work best
- 35-inch tires: You’ll need a cover for 35-37 inches
- 37-inch and up: Oversized covers are available
If you have a lifted Wrangler with bigger tires, measure twice. Some covers are designed specifically for lifted Jeeps with aftermarket wheels.
Installation: Step-By-Step Guide
Installing a spare tire cover is simple. Most covers slip over the tire and tighten with a drawstring or strap. Some have a locking mechanism for extra security. Here’s how to do it right.
- Clean the spare tire with a damp cloth to remove dirt and debris. This prevents scratches on the cover’s interior.
- If your cover has a plastic backing or foam insert, place it behind the tire first. This helps the cover stay in shape.
- Slide the cover over the top of the tire. Pull it down evenly on all sides. Don’t force it—if it’s too tight, you may need a larger size.
- Adjust the cover so the design or logo is centered. Most covers have a small cutout for the valve stem. Align that with your tire’s valve.
- Tighten the drawstring or strap at the bottom. Pull it snug but not too tight—you don’t want to damage the cover or tire.
- If your cover has a lock, secure it now. Some covers use a cable lock that wraps around the tire and gate.
That’s it. The whole process takes about 5 minutes. If the cover feels loose after a few days, retighten the drawstring. Some covers stretch slightly over time.
Maintenance And Care Tips
A good cover lasts 2-3 years with proper care. Here’s how to extend its life.
- Wash the cover every few months with mild soap and water. Avoid harsh detergents that can fade the color.
- Rinse thoroughly to remove soap residue. Let it air dry completely before putting it back on.
- Check for mold or mildew, especially if you live in a humid area. If you see spots, clean with a vinegar-water solution.
- Remove the cover occasionally to let the tire breathe. This prevents moisture from getting trapped.
- Store the cover inside during winter if you don’t drive your Jeep. Cold can make vinyl brittle.
If your cover starts to fade or crack, replace it. A damaged cover won’t protect your tire and can look sloppy.
Customization Options
One of the best things about a spare tire cover is how much you can customize it. You’re not stuck with plain black. Here are popular options:
- Solid colors: Match your Jeep’s paint or go with a contrasting shade
- Camouflage: Popular for off-roaders who want a rugged look
- Logo designs: Show off brands like Jeep, Rubicon, or your own decal
- American flag: A classic choice that never goes out of style
- Custom text: Add your name, trail name, or a funny saying
Many companies offer custom printing. You can upload your own design or choose from templates. Prices vary, but expect to pay $30-$80 for a custom cover.
Common Problems And Solutions
Even a good cover can have issues. Here are fixes for the most common ones.
Cover Flapping At Highway Speeds
This usually means the cover is too loose. Tighten the drawstring or strap. If it still flaps, try a cover with a rigid backplate that holds its shape.
Moisture Buildup Behind The Cover
Breathable covers help, but if you see condensation, remove the cover for a day to let the tire dry. You can also add a small vent hole (carefully) to improve airflow.
Cover Fading After A Few Months
UV rays are tough. Choose a cover with UV-resistant coating. Park with the rear facing away from the sun when possible. Some covers come with a warranty against fading.
Cover Not Fitting Over Aftermarket Wheels
Aftermarket wheels often have different backspacing, which can push the tire out farther. Measure the overall width of the tire and wheel combo. You may need an oversized cover.
Security Considerations
Spare tire theft is a real concern, especially for lifted Jeeps with expensive tires. A cover alone won’t stop a thief, but it adds a layer of difficulty. Some covers come with a locking cable that loops through the wheel and around the gate hinge.
For maximum security, combine a cover with a dedicated spare tire lock. These locks replace the lug nuts on the spare and require a special key to remove. They’re cheap insurance for a $300 tire.
Budget Vs. Premium Covers
You can spend anywhere from $15 to $150 on a cover. Here’s what you get at each price point.
- Budget ($15-$30): Basic vinyl or polyester. They work but may fade or crack within a year. Good for temporary use or if you’re on a tight budget.
- Mid-range ($30-$60): Better materials, UV protection, and more design options. Most owners find this range offers the best value.
- Premium ($60-$150): Neoprene or heavy-duty polyester with reinforced stitching. Often include a backplate, lock, and warranty. Ideal for daily drivers in harsh climates.
Don’t overspend if you only drive your Jeep on weekends. But if it’s your daily driver, a premium cover pays off in the long run.
Frequently Asked Questions
Can I Use A Universal Spare Tire Cover On My Jeep Wrangler?
Yes, but you need to match the size. Universal covers fit a range of diameters. Measure your tire first. Some universal covers don’t have a cutout for the valve stem, so you may need to make one.
How Often Should I Replace My Jeep Wrangler Spare Tire Cover?
Every 2-3 years, depending on sun exposure and material quality. If you see cracks, fading, or loose stitching, replace it sooner.
Will A Cover Protect My Spare From Theft?
It helps, but it’s not foolproof. A cover with a locking cable is more secure. For best protection, use a dedicated spare tire lock in addition to the cover.
Can I Wash My Cover In A Washing Machine?
Only if the label says machine-washable. Most vinyl covers should be hand-washed. Polyester covers can go in the machine on a gentle cycle, but air dry only.
Do I Need A Cover If I Have A Hardtop?
Yes. The spare is still exposed to the elements, even with a hardtop. UV rays and rain affect the tire regardless of the roof.
Final Thoughts
Choosing the right Jeep Wrangler spare tire cover is about balancing protection, style, and budget. Measure your tire, pick a material that suits your climate, and install it correctly. With a little care, your cover will keep your spare looking good and lasting longer.
Don’t forget to check the cover’s fit after a few weeks. Tires can settle or change shape slightly. A quick adjustment keeps everything snug. And if you’re into off-roading, consider a cover with a rugged design that can handle mud and brush.
Your Jeep is an investment. A simple cover protects that investment and adds a personal touch. Take five minutes to measure and order one today. Your spare tire will thank you.
