2019 Dodge Ram Big Horn Tire Size Guide

Hey guys, welcome back! Today, we're diving deep into a topic that's super important for your ride: the tire size for your 2019 Dodge Ram Big Horn. Choosing the right tires isn't just about looks; it's about performance, safety, and even fuel economy. So, if you've been scratching your head wondering, "What size tires fit my 2019 Ram Big Horn?" you've come to the right place. We'll break down the stock sizes, explore upgrade options, and give you the lowdown on why it all matters.

Understanding Your Stock Tire Size

Alright, let's get down to business. The 2019 Dodge Ram Big Horn, like many trucks, came with a few different tire size options depending on the specific configuration and packages. However, the most common OEM (Original Equipment Manufacturer) tire sizes you'll find on the 2019 Ram Big Horn are typically 275/65R18 and 275/55R20. Let's decode what those numbers mean, shall we? The first number, 275, refers to the tire's width in millimeters. So, you've got a 275mm wide footprint. The second number, 65 or 55, is the aspect ratio – it's the tire's sidewall height as a percentage of its width. A 65 aspect ratio means the sidewall is 65% of 275mm, and a 55 means it's 55% of 275mm. The letter 'R' simply stands for Radial construction, which is standard on pretty much all modern tires. Finally, the 18 and 20 indicate the diameter of the wheel, in inches, that the tire is designed to fit. So, you're looking at either 18-inch or 20-inch wheels. Knowing these stock sizes is your baseline. If you're just replacing a worn-out tire, sticking to these numbers is usually the safest bet. It ensures your speedometer and other vehicle systems are calibrated correctly. Plus, it means no modifications are needed to your suspension or fenders. Easy peasy!

Why Tire Size Matters for Your Ram Big Horn

So, why all the fuss about tire size for your 2019 Dodge Ram Big Horn? Well, guys, it's a big deal for a few reasons. First off, performance. The tire size directly impacts your truck's handling, grip, and braking. A wider tire might give you better traction, especially in dry conditions, while a tire with a taller sidewall could offer a more comfortable ride. Think about it: a bigger contact patch means more rubber hitting the road, which can translate to better acceleration and stopping power. On the flip side, if you go too big or too wide without the right setup, you could actually reduce your performance. Your speedometer and odometer are calibrated for specific tire sizes, so changing them significantly without recalibration can throw off your readings. Imagine thinking you're going 60 mph when you're actually doing 65, or vice versa! That's not ideal. Then there's fuel economy. Larger, heavier tires often require more energy to spin, which means your engine has to work harder, leading to lower MPG. It's a trade-off: sometimes a more aggressive tire that looks awesome might cost you a bit more at the pump. Safety is another huge factor. The wrong size tire can affect your truck's stability, especially during cornering or emergency maneuvers. You want tires that are designed to work with your truck's suspension and braking system. Plus, fitting oversized tires can sometimes lead to rubbing against your fenders or suspension components, which is not only annoying but can also damage your truck. We definitely don't want that! Lastly, load capacity and towing. Your tires have a specific load rating, and changing to a different size or type of tire can alter how much weight your truck can safely handle. If you're using your Big Horn for towing or hauling heavy loads, this is something you absolutely need to consider. Always check the load index on the tire sidewall and ensure it meets or exceeds your truck's requirements.

Exploring Tire Upgrade Options

Now, let's talk upgrades! Many Ram owners love to customize their trucks, and changing the tire size on a 2019 Dodge Ram Big Horn is a popular way to do it. Whether you want a more aggressive look, better off-road capability, or just a smoother ride, there are options. A common upgrade is to go from the stock 18-inch wheels to larger 20-inch wheels, or vice versa, if you prefer a beefier tire profile. Many people also choose to go up one size in tire diameter, for example, moving from a 275/65R18 to a slightly larger all-terrain tire like a 275/70R18 or even a 33-inch equivalent, provided there's enough clearance. All-terrain (AT) tires are a fantastic choice for Ram owners who want a blend of on-road comfort and off-road prowess. They have a more aggressive tread pattern than highway tires, offering better grip in mud, dirt, and gravel, but are still quiet enough for daily driving. For those who want maximum off-road grip, mud-terrain (MT) tires are the way to go. They have deep, widely spaced lugs that excel in challenging terrain but can be noisy and less fuel-efficient on the highway. If you're planning on significant off-roading or hitting challenging trails, MTs are worth considering. On the flip side, if your truck is primarily a daily driver and you rarely venture off pavement, highway-terrain (HT) tires or all-season tires might be a better fit, offering a quieter, more comfortable ride and better fuel economy. When considering upgrades, always check for potential rubbing. A slightly larger tire might fit without modification, but going too big without a lift kit or leveling kit could cause issues. Many online tire calculators can help you compare the dimensions of different tire sizes to your stock ones. Remember, if you significantly change your tire size, you might need to recalibrate your speedometer and odometer to ensure accurate readings. This can often be done with a programmer tool. Don't forget about the wheel offset and backspacing too, as these factors also play a role in how a tire fits and whether it will rub.

Factors to Consider When Choosing New Tires

When you're on the hunt for new tires for your 2019 Dodge Ram Big Horn, there are a few key things to keep in mind. First, your driving habits. Are you mostly cruising on the highway? Do you tackle rough roads or go off-roading? Are you hauling heavy loads or towing a trailer? Your answers will guide you toward the right type of tire. For highway cruising, highway-terrain (HT) or all-season tires are usually the best bet for comfort and fuel efficiency. If you venture onto dirt roads or deal with occasional mud or snow, all-terrain (AT) tires offer a great balance. For serious off-roading, mud-terrain (MT) tires are king, but be prepared for a noisier ride and reduced fuel economy. Second, weather conditions. If you live somewhere with harsh winters, snow tires or all-terrain tires with the
