Navigating the world of vehicle customization can be daunting, especially when it comes to finding the perfect tire for your Jeep Rubicon. Many Jeep enthusiasts are constantly seeking ways to maximize their vehicle’s performance without resorting to extensive and often costly modifications. One of the most effective methods to enhance your Jeep’s capabilities is to install the largest tires possible.

But what are the biggest tires for a stock Jeep Wrangler Rubicon you can install without lifting or modifying your vehicle? This guide will provide comprehensive information about just that, walking you through the factors you need to consider and the steps you need to take.

Understanding Your Jeep Rubicon’s Tire Specifications 

Understanding Your Jeep Rubicon's Tire Specifications 

Before diving into the topic of installing larger tires, it’s crucial to understand your stock Jeep Rubicon’s tire specifications. These parameters will guide you in choosing larger tires that are still compatible with your Rubicon.

Stock Tire Specifications

The stock tires for a Jeep Wrangler Rubicon typically measure 33 inches in diameter, fitting perfectly within the stock suspension setup. The exact specifications may vary slightly depending on the model year of your stock Jeep Rubicon, but the size remains relatively consistent across models.

The Significance of Tire Size 

Larger tires not only contribute to your Jeep’s aggressive aesthetic but also significantly improve its off-road performance. They provide greater ground clearance, traction, and overall capability. However, when fitting bigger tires, you should be aware that excessively large tires may cause rubbing against the fenders or wheel wells, particularly when turning or off-roading.

What Are the Biggest Tires for a Stock Jeep Wrangler Rubicon? 

While some people may ponder about stock Jeep Rubicons lifted, many are seeking information on the maximum tire size that can fit on a stock Rubicon without the need for a lift kit or modifications.

The 35-Inch Rule

Generally, the biggest tires you can fit on a stock Jeep Wrangler Rubicon without making any modifications are 35 inches. However, the specifics may vary depending on the model year and exact trim of your Rubicon, as well as the brand and design of the tires you choose. This size often fits well with the stock wheels, maintaining the vehicle’s balance and aesthetics.

Wheel Offset and Backspacing 

One aspect to consider when fitting larger tires is the wheel offset and backspacing. These two factors can determine how far the tire sticks out from the vehicle and how far it sits inside the wheel well.

Proper offset and backspacing are crucial to prevent the tires from rubbing against the suspension components or the fenders, especially when turning or going off-road. Some 35-inch tires may require wheels with specific offset and backspacing to fit properly.

Tire Width Considerations

 While the diameter of the tire is a crucial factor, the width of the tire also plays a significant role. Wider tires provide more surface contact, which can improve traction. However, they may also increase the risk of rubbing.

When selecting the biggest tires for a stock Jeep Wrangler Rubicon, keep in mind that the increase in size should not compromise the functionality of the vehicle.

Potential Rubbing Issues 

Even though a 35-inch tire should generally fit a stock Rubicon, some owners have reported occasional rubbing issues. These often occur during full compression of the suspension or during sharp turns.

The extent of this problem can vary based on the tire brand, design, and the specific model year of the Jeep. While some minor rubbing might not be a deal-breaker for off-road enthusiasts, it’s something to consider when choosing the biggest tires.

Specific Tire Brands and Models 

When determining the biggest tires for your stock Jeep Wrangler Rubicon, not all 35-inch tires are created equal. Specific brands and models may offer different tread designs, rubber compounds, and sidewall constructions.

These differences can affect the overall diameter and profile of the tire when mounted, which could impact whether or not the tire fits without modification. Always do your due diligence when researching tire brands and models to find the best fit for your Rubicon.

Choosing the Right Tires for Your Jeep Rubicon

Even within the parameters of the largest possible tire size for a stock Jeep Wrangler Rubicon, there’s a variety of tire types to choose from. Your choice should be informed by your driving conditions, terrain, and personal needs.

All-Terrain Tires 

All-terrain tires are ideal if your driving includes a mix of on-road and off-road terrains. These tires offer a balance of road comfort, traction, and durability, making them a versatile choice.

Mud-Terrain Tires 

For those frequently venturing off-road or into challenging terrains, mud-terrain tires could be more suitable. With aggressive tread patterns, these tires are designed to deliver maximum traction in off-road conditions.

Snow/Winter Tires

If you live in an area with severe winters, you might want to consider snow/winter tires. These are designed to provide optimal traction in snowy and icy conditions.

Highway Tires 

For primarily on-road use and highway driving, highway tires are a great option. They are designed for comfort, fuel efficiency, and long tread life, but they may not perform as well off-road.

Performance Tires

If you use your Jeep for speed and sporty driving, performance tires may be the best option. These tires are designed to provide excellent grip and handling at higher speeds, but they may not offer the best comfort or tread life.

Off-road Bias Tires 

Off-road bias tires are designed primarily for off-road use. They offer excellent traction in mud, rocks, and dirt but can be noisy and uncomfortable on the pavement.

Choosing the Right Tire Brand 

The brand of the tire can significantly impact the tire’s performance and longevity. It’s advisable to go for reputable brands known for their quality and durability.

Reading Tire Reviews 

Always take the time to read reviews from other Jeep owners. This can provide insight into how the tires perform in real-world conditions and might highlight any potential issues.

Balancing Budget and Quality 

When choosing tires, it’s essential to strike a balance between budget and quality. More expensive tires often offer better performance and longevity but at a higher cost.

Tire Warranty Considerations 

Lastly, check the warranty offered by the tire manufacturer. This could provide added peace of mind and can be a deciding factor between two similar tire options.


Fitting the largest possible tires on your Rubicon without resorting to lifting or modifying your vehicle can significantly enhance your vehicle’s performance and aesthetic appeal. The largest tires for a stock Jeep Wrangler Rubicon are typically 35 inches. However, a lot depends on factors such as wheel offset and backspacing, tire width, potential rubbing issues, and specific tire brands and models.

When choosing the right tire, consider the type of terrain you’ll be navigating, the quality of the tire, your budget, and the brand reputation. Remember, the goal is not just to install the biggest tires but to enhance your driving experience, on and off-road. With the right research and approach, you’ll have your Jeep Rubicon outfitted with tires that perfectly match your driving style and requirements.
