Hey guys! If you're looking to upgrade or replace the tires on your 2019 Dodge Ram Big Horn, you've come to the right place! Ensuring you have the correct tire size is super important for your truck's performance, safety, and overall look. Let's dive into everything you need to know about the right tire sizes for your Big Horn.

Understanding Tire Sizes for Your 2019 Dodge Ram Big Horn

When it comes to your 2019 Dodge Ram Big Horn tire size, understanding the factory specifications is the first step. Generally, the standard tire sizes can vary based on the specific configuration of your truck, such as whether it’s a 2WD or 4WD model, and the trim level. However, here are some common factory tire sizes you might find:

• 275/60R20: This is a very common size found on many Big Horn models. The "275" represents the tire's section width in millimeters, "60" is the aspect ratio (the height of the sidewall as a percentage of the section width), "R" indicates it's a radial tire, and "20" is the wheel diameter in inches.
• 275/65R18: Another potential option, especially for models with 18-inch wheels. This size has a slightly taller sidewall compared to the 20-inch version, which can offer a more comfortable ride and better off-road performance.
• Other Sizes: Depending on specific packages and options, you might find slightly different sizes. Always double-check your truck's door placard or owner's manual for the exact original equipment manufacturer (OEM) tire size.

Why is it so important to stick to the recommended tire sizes? Well, using the correct size ensures that your speedometer and odometer read accurately. It also maintains the proper load-carrying capacity and avoids any potential clearance issues with the suspension or body of your truck. Plus, it keeps your truck handling the way the engineers designed it to!

Why Correct Tire Size Matters

Choosing the correct tire size for your 2019 Dodge Ram Big Horn is more than just a matter of aesthetics; it’s crucial for performance, safety, and the longevity of your vehicle. Here’s why:

• Speedometer and Odometer Accuracy: Using a tire size different from the original equipment manufacturer (OEM) tire size can throw off your speedometer and odometer readings. This happens because the tire's rolling circumference changes. If the rolling circumference is smaller, your speedometer will read higher than your actual speed, and your odometer will accumulate miles faster. Conversely, a larger rolling circumference will cause your speedometer to read lower, and your odometer will record fewer miles. Accurate readings are essential for tracking maintenance intervals, complying with speed limits, and getting precise fuel economy data.
• Handling and Stability: The tire size significantly impacts your truck's handling and stability. The engineers at Dodge designed the suspension and other vehicle systems to work optimally with specific tire dimensions. Deviating from these dimensions can compromise the vehicle's handling characteristics, making it less stable and predictable, especially during emergency maneuvers or in adverse weather conditions. Maintaining the recommended tire size ensures that your truck performs as intended, providing a safe and controlled driving experience.
• Load Capacity: Each tire has a specific load index, indicating the maximum weight it can carry safely. Using the correct tire size ensures that the tires can handle the load requirements of your 2019 Dodge Ram Big Horn. Overloading tires can lead to premature wear, tire failure, and potentially dangerous situations. Sticking to the recommended size guarantees that your tires can support the weight of your truck, passengers, and cargo without compromising safety.
• Clearance: The tire size affects the clearance between the tires and the vehicle's body and suspension components. Using tires that are too large can cause rubbing against the wheel wells or suspension parts, leading to damage to both the tires and the vehicle. This rubbing can also create noise and vibration, reducing ride comfort. Conversely, tires that are too small may not provide adequate ground clearance, increasing the risk of damage to the undercarriage of your truck.
• Fuel Efficiency: The tire size can also influence your truck's fuel efficiency. Larger tires generally have a greater rolling resistance, which means the engine has to work harder to turn them. This increased effort translates into lower fuel economy. While the impact may not be dramatic, it can add up over time. Sticking to the OEM tire size helps maintain the optimal balance between performance and fuel efficiency.

In summary, the tire size is a critical factor in ensuring the safety, performance, and longevity of your 2019 Dodge Ram Big Horn. Always consult your owner's manual or the tire placard on your vehicle to determine the recommended tire size and adhere to those specifications when replacing or upgrading your tires.

Checking Your Current Tire Size

Alright, before you rush out and buy new tires, let's make sure you know how to check your current tire size. This is super easy, guys, and it'll save you a lot of headaches later on. Here’s a simple step-by-step guide:

1. Locate the Tire Sidewall: Go to any of your tires and look at the sidewall. You'll see a series of numbers and letters – that's the code that tells you everything about your tire.
2. Read the Code: The tire size code will look something like this: 275/60R20. Let's break it down:
   • 275: This is the section width of the tire in millimeters. Basically, it’s how wide the tire is from sidewall to sidewall.
   • 60: This is the aspect ratio, which is the height of the tire's sidewall as a percentage of its width. So, in this case, the sidewall is 60% as tall as the tire is wide.
   • R: This indicates that the tire is a radial tire. Almost all modern tires are radial.
   • 20: This is the diameter of the wheel in inches. It tells you what size wheel the tire is designed to fit.
3. Check the Door Placard: Another great place to find the recommended tire size is on the door placard. This is a sticker usually located on the driver's side doorjamb. It provides essential information about your vehicle, including the OEM tire size, recommended tire pressure, and the vehicle's load capacity.
4. Consult Your Owner's Manual: If you're still unsure, your owner's manual is your best friend. It contains detailed information about your vehicle, including the recommended tire sizes for different configurations and driving conditions.

By following these simple steps, you can easily determine the correct tire size for your 2019 Dodge Ram Big Horn and ensure you're getting the right tires for your truck. It’s always a good idea to double-check this information before making a purchase to avoid any fitment issues or performance problems.

What About Alternative Tire Sizes?

Okay, so you know your OEM tire size, but what if you're thinking about going a little bigger or smaller? Here's the deal with alternative tire sizes:

• Upsizing: Some owners choose to upsize their tires for a more aggressive look or to gain a bit more ground clearance. If you're considering this, make sure the new tires won't rub against the suspension or fender wells, especially when turning. You'll also want to ensure that the larger tires don't negatively impact your truck's handling or put undue stress on the drivetrain.
• Downsizing: Downsizing is less common, but some people do it for better fuel economy or ride comfort. Just like with upsizing, make sure the smaller tires are still rated to handle the load capacity of your truck. Also, keep in mind that smaller tires can reduce ground clearance and may affect the truck's appearance.

Before making any changes, it's always a good idea to consult with a tire professional. They can help you choose alternative sizes that will work well with your 2019 Dodge Ram Big Horn without causing any problems. Also, use online tire size calculators to compare different sizes and see how they'll affect your speedometer reading.

Choosing the Right Tire Type

Beyond size, the type of tire you choose is also crucial. Here are some popular options:

• All-Season Tires: These are the most common type and offer a good balance of ride comfort, handling, and tread life. They're suitable for most driving conditions, including light snow.
• All-Terrain Tires: If you do a lot of off-roading or driving on unpaved roads, all-terrain tires are a great choice. They have a more aggressive tread pattern for better traction in dirt, mud, and gravel.
• Mud Tires: For serious off-road enthusiasts, mud tires provide maximum traction in deep mud and soft soil. However, they can be noisy on the road and may wear out more quickly than other types.
• Winter Tires: If you live in an area with heavy snow and ice, winter tires are a must. They have a special tread compound that stays flexible in cold temperatures and provides excellent grip on slippery surfaces.

Consider your driving habits and the conditions you typically encounter when choosing the right tire type for your 2019 Dodge Ram Big Horn. Also, check online reviews and ratings to see what other owners have to say about different tires.

Where to Buy Tires

So, you've figured out the correct tire size and type for your 2019 Dodge Ram Big Horn. Now, where should you buy them?

• Local Tire Shops: These shops often offer personalized service and can help you choose the right tires for your needs. They may also offer installation and balancing services.
• Chain Tire Stores: Stores like Discount Tire and Firestone offer a wide selection of tires and competitive prices. They also have online tools that can help you find the right tires for your vehicle.
• Online Retailers: Online retailers like Tire Rack and Amazon offer a convenient way to shop for tires from the comfort of your own home. Just make sure to factor in shipping costs and installation fees.

Compare prices and read reviews before making a purchase. Also, check for any rebates or promotions that can save you money.
