So, you're the proud owner of a 2020 Jeep Gladiator Overland, and you're probably wondering about the best tire size to slap on that bad boy. You've come to the right place! Figuring out the perfect tire size can be a bit of a rabbit hole, but don't sweat it. We'll break it down, so you can make the best choice for your needs, whether you're hitting the trails or cruising down the highway. Let’s dive in, guys!

Understanding the Stock Tire Size

First things first, let's talk about the stock tire size on your 2020 Gladiator Overland. Knowing this is crucial because it gives you a baseline to work from. Generally, the Overland trim comes with 255/70R18 tires. This means the tire is 255 millimeters wide, the aspect ratio (sidewall height as a percentage of the width) is 70%, and it fits an 18-inch wheel. These tires are a decent all-around choice from the factory, balancing on-road comfort with some off-road capability. However, many Gladiator owners quickly start thinking about upsizing for a more aggressive look or better performance in specific conditions.

When you're thinking about changing tire sizes, keep a few things in mind. The overall diameter of the tire affects your speedometer and odometer readings. A significantly larger tire can make your speedometer read lower than your actual speed. Also, bigger tires can sometimes rub against the fender liners or suspension components, especially when turning or flexing off-road. That's why it's super important to do your homework and understand what fits without causing issues. Don't just slap on the biggest tires you can find without considering the consequences!

Another thing to consider is the effect on your Gladiator's performance. Larger, heavier tires can decrease your fuel economy and acceleration. They add more rotational mass, which means your engine has to work harder to get them moving. On the other hand, bigger tires can provide more ground clearance and better traction in off-road situations. It's all about finding the right balance for your specific needs and driving style. Are you mostly on the pavement, or are you tackling rocky trails every weekend? The answer to that question will heavily influence your tire size decision.

Considering Upsizing: What Fits?

Okay, so you're thinking about going bigger. Great! But how big is too big? A popular and generally safe upsizing option for the 2020 Gladiator Overland is 285/70R17 or 285/65R18. These sizes are usually accommodated without any modifications, especially if you stick with the stock wheels or wheels with a similar offset. The 285 width gives you a slightly wider stance and a more aggressive look, while the increased diameter provides a bit more ground clearance. Plus, these sizes are widely available, so you'll have plenty of tire choices.

Now, if you're itching to go even bigger, like 35-inch tires (e.g., 315/70R17), you'll likely need to make some modifications. This usually involves a leveling kit or a small lift kit to create enough clearance. A leveling kit raises the front of the Gladiator to match the height of the rear, giving it a more balanced look and providing a bit more room for larger tires. A lift kit, on the other hand, raises both the front and rear, providing even more clearance. Keep in mind that lifting your Gladiator can affect its handling and ride quality, so it's essential to choose a quality kit and have it installed properly.

Another modification you might need with larger tires is adjusting the Jeep's computer to recalibrate the speedometer. As mentioned earlier, larger tires can throw off your speedometer reading, and nobody wants to get a speeding ticket because their speedometer is inaccurate! A tuner or programmer can be used to adjust the computer for the new tire size, ensuring accurate readings and proper shifting of the automatic transmission. This is a relatively simple process, but it's often overlooked, so make sure to factor it into your plans.

Factors to Consider Before Choosing a Tire Size

Before you pull the trigger on a new set of tires, there are several factors you should consider to ensure you're making the best choice for your needs and your Gladiator. Let's break it down:

• Your primary use: Are you mostly driving on the road, or are you frequently hitting the trails? If you're primarily on the pavement, you might want to prioritize a tire with good on-road manners, low noise, and long tread life. If you're an avid off-roader, you'll want a tire with aggressive tread, strong sidewalls, and excellent traction in mud, sand, and rocks.
• Wheel offset: The offset of your wheels plays a big role in how tires fit. Offset refers to the distance from the wheel's mounting surface to its centerline. A different offset can change where the tire sits in relation to the fender and suspension. If you're using aftermarket wheels, make sure the offset is compatible with the tire size you're considering. A wrong offset can cause rubbing issues or even affect the handling of your Gladiator.
• Load rating: Pay attention to the load rating of the tires. The load rating indicates the maximum weight each tire can carry. Make sure the tires you choose have a load rating that meets or exceeds the requirements for your Gladiator. Overloading tires can lead to premature wear and even tire failure, which is definitely something you want to avoid.
• Tire type: There are several types of tires to choose from, including all-season, all-terrain, mud-terrain, and winter tires. All-season tires are a good compromise for on-road driving in various conditions. All-terrain tires offer a balance of on-road and off-road performance. Mud-terrain tires are designed for extreme off-road use, with aggressive tread patterns for maximum traction in mud and rocks. Winter tires are designed for optimal performance in snow and ice. Choose the tire type that best suits your driving conditions and needs.

Popular Tire Choices for the 2020 Gladiator Overland

Alright, let's get down to some specific tire recommendations. Here are a few popular choices among Gladiator owners, covering different tire types and sizes:

• BFGoodrich All-Terrain T/A KO2: This is a classic all-terrain tire that's known for its durability, traction, and relatively quiet ride on the road.

This tire is also available in sizes that fit the Gladiator Overland without modifications, making it a popular choice.
• Falken Wildpeak A/T3W: The Wildpeak A/T3W is another popular all-terrain tire that offers a great balance of on-road and off-road performance.

However, it's worth noting that the Duratrac can be a bit more expensive than some other options.

Maintaining Your Tires

Once you've chosen the perfect tire size and type for your 2020 Gladiator Overland, it's important to maintain them properly to ensure they last as long as possible and perform at their best. Here are a few tips:

• Check your tire pressure regularly: Proper tire pressure is crucial for optimal performance, fuel economy, and tire life. Check your tire pressure at least once a month, and always before a long trip. Use a quality tire pressure gauge and inflate your tires to the recommended pressure, which can be found on a sticker inside the driver's side doorjamb or in your owner's manual.
• Rotate your tires: Rotating your tires helps to ensure even wear and prolong their lifespan. The recommended rotation interval is typically every 5,000 to 8,000 miles, but it's always a good idea to consult your owner's manual or a tire professional for specific recommendations.
• Balance your tires: Balanced tires provide a smoother ride and prevent premature wear. If you notice vibrations or uneven wear patterns, it's a good idea to have your tires balanced. This is typically done when you rotate your tires.
• Inspect your tires regularly: Visually inspect your tires for any signs of damage, such as cuts, bulges, or uneven wear. If you notice any problems, have them addressed promptly by a tire professional. Catching problems early can prevent more serious issues down the road.
