Hey Jeep enthusiasts! So, you're rolling in a brand-new 2023 Gladiator Rubicon – awesome choice, guys! This beast is built for adventure, and the right tires are key to unlocking its full potential. Today, we're diving deep into the world of 2023 Gladiator Rubicon tire sizes, covering everything from stock dimensions to the possibilities of upsized rubber. Whether you're planning to conquer the trails or just want a more aggressive look for your daily commute, this guide has you covered. We'll explore the factory tire specs, factors influencing your tire choices, and some tips to ensure a smooth and safe upgrade. Let's get this show on the road, shall we?

Stock Tire Size: The Foundation of Your Gladiator's Footprint

Alright, let's start with the basics. The 2023 Gladiator Rubicon typically rolls off the assembly line equipped with 33-inch tires. Specifically, the stock tire size is 285/70R17. This size is a sweet spot, offering a good balance of on-road comfort and off-road capability. This setup allows for decent ground clearance and provides a good foundation for tackling various terrains right from the factory. The 285/70R17 designation breaks down like this:

• 285: This number represents the tire's width in millimeters. So, a 285mm wide tire is pretty substantial, providing a good contact patch with the ground.
• 70: This is the aspect ratio, indicating the tire's sidewall height as a percentage of its width. In this case, the sidewall height is 70% of 285mm.
• R: This signifies that the tire is a radial tire, the most common type for modern vehicles.
• 17: This is the wheel diameter in inches. Your Rubicon's stock wheels are 17 inches.

Understanding these numbers is crucial for making informed decisions about tire upgrades. Knowing the stock size allows you to compare and contrast with larger options, ensuring you don't go too big without the necessary modifications. But why is the stock tire size important, anyway? Well, it is engineered to work well with your Gladiator's suspension, steering, and braking systems without any adjustments. The engineers at Jeep spent a lot of time perfecting this formula, and it's a great starting point for assessing other tire sizes.

Now, don't just take my word for it. Check your Gladiator's tire placard, usually located on the driver's side doorjamb. This placard provides the recommended tire size and inflation pressure, which is essential information. It also lists the vehicle's load capacity and other important specifications. So, while we're talking about upgrading, always keep safety first and consider the load-carrying capacity of your Gladiator. You don't want to overload your tires, which can lead to premature wear or, worse, a tire failure. Make sure the tires you choose are rated for the weight of your vehicle and the loads you intend to carry, particularly if you do any heavy-duty towing or hauling.

Finally, remember that the stock tire size is only a starting point. Your needs and preferences might push you towards a different tire size. Maybe you're looking for more ground clearance, or perhaps you want a more aggressive tread pattern for better off-road grip. Whatever your goals, always keep the stock size as a reference point. Also, consider that changing your tire size can affect your speedometer and odometer readings, so you might need to recalibrate your vehicle's systems to ensure accurate readings.

Upgrading Your Tires: Exploring Larger Sizes

Alright, so you're itching to go bigger, eh? I get it. Bigger tires often mean more ground clearance, a more aggressive look, and improved off-road performance. But before you jump into buying the biggest tires you can find, there are a few things you need to consider. Firstly, let's talk about the maximum tire size you can fit on a 2023 Gladiator Rubicon without any modifications. Generally speaking, you can squeeze in a 35-inch tire without making any significant changes. However, there are some caveats.

With a 35-inch tire, you might experience some rubbing, especially during off-road articulation or while turning sharply. To eliminate this, you might need to install a lift kit. A lift kit raises your Gladiator's suspension, providing more clearance for larger tires. There are several types of lift kits available, ranging from simple leveling kits to full-blown long-arm suspension systems. The type of lift kit you choose depends on your budget, your intended use of the vehicle, and the level of performance you desire. A leveling kit will provide a modest lift, often enough to fit 33-inch or some 35-inch tires. A full suspension lift will give you a more significant increase in ground clearance and articulation, but it will also be more expensive and require more complex installation.

Beyond a lift kit, there are other potential modifications to consider. For example, you might need to trim or modify your fender flares or bumpers to prevent rubbing. You might also need to adjust your steering stops to limit the turning radius and prevent the tires from contacting the inner fenders. And, as always, keep in mind the potential impact on your speedometer and odometer. When you increase the tire size, your speedometer will read slower than your actual speed, and your odometer will record fewer miles than you've actually driven. Many vehicles allow for recalibration to correct this issue; some use a programmer, while others can be adjusted through the vehicle's onboard computer. Make sure you check your local laws to ensure that your vehicle remains compliant with regulations after the modifications.

Here's a quick rundown of some common tire sizes that are popular upgrades for the 2023 Gladiator Rubicon:

• 33x12.50R17: This is a common upgrade that provides a wider tire and a more aggressive look, offering great off-road traction.
• 35x12.50R17: This size requires some modifications, such as a lift kit, but provides significantly more ground clearance and capability.
• 37x12.50R17: This is a much bigger tire, and it will require extensive modifications, including a lift kit, regearing, and possibly even modifications to the axles.

When you're choosing a tire size, consider your intended use of the vehicle. If you primarily drive on-road, a slightly larger tire size might be a good choice, as it will improve the look without significantly affecting ride quality or fuel economy. However, if you plan to do a lot of off-roading, you might want to go with a larger tire size, even if it requires more modifications. Consider the type of terrain you plan to tackle. If you plan to tackle rocks, mud, or sand, a tire with an aggressive tread pattern will be essential. If you primarily drive on pavement, a tire with a less aggressive tread pattern might provide better ride quality and fuel economy.

Factors to Consider When Choosing Tire Size

Alright, let's get down to the nitty-gritty and talk about the factors that influence your tire-size decision. It's not just about what looks cool; there's a lot more to it than that. Choosing the correct tire size involves a delicate balance of performance, aesthetics, and practicality. You don't want to end up with tires that rub, negatively affect your vehicle's performance, or simply don't suit your needs. Here are the crucial factors you need to consider:

• Lift Kit: As mentioned previously, the lift kit is important. Installing a lift kit is frequently necessary to accommodate larger tires. The height of the lift kit will determine the maximum tire size you can fit. Keep in mind that a lift kit can affect your vehicle's center of gravity, potentially impacting handling. Always choose a lift kit that matches your driving style and the terrain you frequent.
• Wheel Size: Your choice of wheel size plays a role too. When you upgrade your tires, you might also want to upgrade your wheels. Wider wheels can accommodate wider tires and provide better stability, but the wheel's offset and backspacing are also crucial considerations to prevent rubbing. Proper wheel fitment is a critical component of any successful tire upgrade.
• Gearing: Changing tire sizes can impact your vehicle's gearing. Larger tires increase the overall gear ratio, which can make your Jeep feel sluggish, especially during acceleration. Regearing your axles can restore your vehicle's performance. The regearing process involves replacing the gears in your axles to provide the correct gear ratio for your larger tires. This ensures that your Jeep maintains its original performance characteristics.
• Tire Load Rating: It is critical to select tires with a load rating that meets or exceeds your Gladiator's requirements. The load rating indicates the maximum weight the tire can carry. If you regularly carry heavy loads, such as camping gear or tools, ensure that your tires are rated to handle the weight.
• Tire Tread Pattern: Consider your driving conditions. Do you primarily drive on pavement, off-road, or a combination of both? Different tread patterns are designed for specific terrain types. For example, all-terrain tires offer a good balance of on-road comfort and off-road capability. Mud-terrain tires provide superior traction in mud and loose terrain but can be noisy and less comfortable on the road. Highway tires are designed for maximum on-road performance, with excellent ride quality and fuel efficiency.
• Speedometer Calibration: As noted earlier, changing your tire size will affect your speedometer and odometer readings. You will need to recalibrate your vehicle's systems to ensure accurate readings. Many vehicles allow for calibration through a programmer or the onboard computer. Proper calibration ensures that your speed and mileage readings are accurate.
