Best Spare Tire Cover Sizes for Jeep Wrangler: The Proven Guide
Jun
Finding the correct spare tire cover sizes for Jeep Wrangler is more involved than it sounds. Unlike most vehicles where the spare tire size is consistent across trims, Jeep Wranglers vary widely — from stock factory setups to heavily lifted off-road builds — and each configuration requires a different cover size.
This guide breaks down exactly which spare tire cover sizes for Jeep Wrangler apply to stock, mildly upgraded, and fully built off-road configurations, and shows you how to confirm the right size for your specific setup before ordering.
Why Spare Tire Cover Sizes for Jeep Wrangler Vary So Much
The Jeep Wrangler is one of the most heavily modified vehicles on the road. Owners routinely upgrade tires as part of lift kits, off-road builds, and aesthetic upgrades — often going from factory 30-inch tires all the way up to 35-inch or larger tires in a single modification.
This means two Jeep Wranglers sitting side by side in a parking lot may look similar but require spare tire covers that differ by three or four inches. Assuming your neighbor’s Wrangler uses the same size as yours is one of the most common Jeep-specific sizing mistakes.
The only reliable way to determine the correct spare tire cover sizes for Jeep Wrangler is to check the actual tire on your vehicle — not the trim level, not the year, and not what another owner uses.
Spare Tire Cover Sizes for Jeep Wrangler: Stock Builds
Stock Jeep Wranglers — meaning those running factory tires with no lift kit or tire upgrades — typically use spare tires in the following range:
- Jeep Wrangler JL (2018–present), stock: Most trims use 255/70R18 or 245/75R17 tires, producing overall diameters of approximately 30–31 inches. Correct cover size: 30″ or 31″
- Jeep Wrangler JK (2007–2018), stock: Factory tires are typically 245/75R17 or 255/75R17, measuring approximately 30–31 inches. Correct cover size: 30″ or 31″
- Jeep Wrangler TJ (1997–2006), stock: Factory tires are typically 225/75R16 or 235/75R15, measuring approximately 28–29 inches. Correct cover size: 28″ or 29″
Always verify by reading the sidewall code on your actual spare tire. Dealer-installed upgrades or previous owner modifications may mean your tire differs from the factory specification.
Spare Tire Cover Sizes for Jeep Wrangler: Mild Upgrades
Mildly upgraded Wranglers — those with a 2–3 inch lift and slightly larger tires — typically fall into this range:
- Tires in the 265/70R17 range → approximately 31.6 inches → cover size: 32″
- Tires in the 275/70R17 range → approximately 32.2 inches → cover size: 32″
- Tires in the 285/70R17 range → approximately 33 inches → cover size: 33″
This is the most common range for everyday Wrangler owners who want slightly more capability without going to an extreme build. The 32″ and 33″ sizes are the most frequently ordered spare tire cover sizes for Jeep Wrangler in this category.
Spare Tire Cover Sizes for Jeep Wrangler: Off-Road and Lifted Builds
Lifted Wranglers with aggressive off-road tires represent the widest range of sizing and also the most complexity. These builds commonly use:
- 33×12.50R17 or 33×12.50R15 → approximately 33 inches → cover size: 33″ (or 34″ V2 if tire is very wide)
- 315/70R17 → approximately 34.4 inches → cover size: 34″ V2
- 35×12.50R17 → approximately 35 inches → cover size: 35″
- 37×12.50R17 → approximately 37 inches → outside standard cover range
For off-road builds, tire width becomes especially important alongside diameter. A 33×12.50R17 tire — the “12.50” indicating a very wide 317mm tire — may fit better in a 34″ V2 than a standard 33″ due to the aggressive width and deep tread projection. This is exactly the scenario where choosing between standard size and V2 matters most.

Important: These are reference values only. Always verify by reading your actual tire’s sidewall code and calculating or measuring the overall diameter before ordering.
The Camera Hole Question for Jeep Wrangler
In addition to size, Jeep Wrangler owners must decide between a cover with or without a camera hole. Many modern Wrangler models — particularly JL models from 2018 onward — have a rear backup camera mounted through the center of the spare tire.
To check whether your Wrangler needs a camera hole:
- Stand directly behind your Jeep
- Look at the center of the spare tire
- If you see a small camera lens visible through the center → choose With Camera Hole
- If there is no lens visible → choose No Camera Hole
Camera hole selection does not affect size. It is a separate option chosen at checkout that determines cover compatibility with your vehicle’s backup camera system.
How to Confirm Your Exact Spare Tire Cover Size for Jeep Wrangler
Use this process to confirm the exact size before ordering:
- Locate the spare tire on your Wrangler. This is typically mounted on the rear tailgate.
- Read the sidewall code. Find the full tire code printed on the sidewall — for example, LT285/70R17.
- Calculate the overall diameter. Enter the sidewall code into a free online tire size calculator to get the overall diameter in inches. Alternatively, measure directly with a tape measure from tread edge to tread edge across the center of the tire.
- Choose the matching cover size. Match the calculated diameter to the closest available size. If between sizes, go larger.
- Assess tire width. If your tires are wide or aggressively treaded, consider whether the 34″ V2 option applies.
Frequently Asked Questions
What is the most common spare tire cover size for Jeep Wrangler?
The most commonly ordered spare tire cover sizes for Jeep Wrangler are 30″, 31″, 33″, and 34″ V2 — reflecting the wide range of stock and modified builds. The 33″ is particularly popular among owners who have upgraded to common off-road tire sizes without going to a full extreme build.
Do all Jeep Wrangler models use the same spare tire cover size?
No. Spare tire cover sizes for Jeep Wrangler vary significantly across model years and trim levels, and vary even more dramatically once tire upgrades are factored in. A stock TJ may need a 28″ cover while a lifted JL Rubicon on 35s needs a 35″ cover — a seven-inch difference on what appears to be the same type of vehicle.
My Jeep is a JK with stock tires. What size do I need?
Most stock Jeep Wrangler JK models use tires that measure approximately 30–31 inches in overall diameter. However, always confirm by reading the sidewall code on your actual spare tire — dealer-installed upgrades or previous owner modifications may mean your tire differs from the standard factory specification.
Should I choose 33″ or 34″ V2 for my 33×12.50R17 tires?
For 33×12.50R17 tires, either size can work — but the 34″ V2 is often the better choice. The “12.50” indicates a very wide tire (approximately 317mm), and the aggressive tread typical of this size benefits from the extra internal room that the V2 provides. If a standard 33″ feels tight or difficult to install on your specific tires, 34″ V2 is the right call.
Final Thoughts
The correct spare tire cover sizes for Jeep Wrangler depends entirely on your specific tire setup — not your model year, trim level, or what other owners use. Stock builds typically range from 28″ to 31″. Mild upgrades land in the 32″–33″ range. Serious off-road builds often need 34″ V2 or 35″.
Check your sidewall code, calculate your diameter, assess your tire’s width and tread profile, and choose accordingly. Two minutes of verification ensures your cover fits perfectly and protects your spare tire for years.
