Hey guys! Are you trying to figure out the right tire size for your 2019 Dodge Ram Big Horn? You're in the right place! Choosing the correct tire size is super important for maintaining your truck's performance, safety, and even its overall look. Let's dive into everything you need to know to make the best choice.

Understanding the Importance of Correct Tire Size

Okay, so why does tire size matter so much? Well, several factors come into play. First off, the right tire size ensures that your speedometer and odometer are accurate. If you're running on tires that are significantly different from the factory specifications, your truck might think it's going faster (or slower) than it actually is, which could lead to some serious issues, especially when it comes to obeying speed limits. Safety is another biggie; the wrong size can mess with your truck's handling and stability, making it less safe, particularly in challenging driving conditions like rain or snow.

Plus, the correct tire size affects your truck's performance. Think about it – the wrong size can impact your acceleration, braking, and even fuel efficiency. No one wants to be stuck with a gas-guzzler because their tires are too big or too small! And let's not forget about aesthetics. The right tires can give your Big Horn that perfect, aggressive stance you're looking for, while the wrong ones can make it look a bit off. Maintaining the proper tire size ensures optimal performance, safety, and fuel efficiency. It's not just about looks; it's about how your truck functions and how safe it is on the road. Proper fitment ensures accurate speedometer readings, prevents undue wear on suspension components, and maintains the intended handling characteristics. Ignoring these aspects can lead to a host of problems, from decreased fuel economy to compromised safety. By sticking to the recommended tire sizes, you ensure that your 2019 Dodge Ram Big Horn performs as intended, providing a smooth, reliable, and safe driving experience. For instance, using tires that are too large can cause rubbing against the wheel wells or suspension components, leading to damage and reduced maneuverability. Conversely, tires that are too small may not provide adequate grip, especially in adverse weather conditions, increasing the risk of skidding and loss of control. It's also worth noting that using non-standard tire sizes can affect your truck's resale value. Potential buyers may be wary of modifications that deviate from the original factory specifications, as they can indicate potential issues or a lack of proper maintenance.

OEM Tire Sizes for the 2019 Dodge Ram Big Horn

So, what were the original (OEM) tire sizes for the 2019 Dodge Ram 1500 Big Horn? This can vary a bit depending on the specific configuration of your truck, like whether it's a 2WD or 4WD model, and any optional packages it might have. But generally, you'll find a few common sizes. Typically, the 2019 Ram 1500 Big Horn came with either 275/65R18 or 275/60R20 tires. These sizes offer a good balance of ride comfort, handling, and appearance. It's always a good idea to double-check the sticker on your driver's side doorjamb. This sticker contains all sorts of useful information about your truck, including the original tire size, recommended tire pressure, and other important details. It's like a cheat sheet specifically for your truck!

Checking the sticker on your driver's side doorjamb is the easiest way to determine the factory-recommended tire size for your 2019 Dodge Ram Big Horn. This sticker provides essential information, including the original tire size and recommended tire pressure. If, for some reason, the sticker is missing or damaged, you can also consult your owner's manual or contact a local Dodge dealership. They should be able to provide you with the correct information based on your truck's VIN (Vehicle Identification Number). Using the correct tire size is crucial for maintaining your truck's performance, safety, and fuel efficiency. The original equipment manufacturer (OEM) tire sizes are designed to work in harmony with your truck's suspension and braking systems. Deviating from these sizes can lead to a variety of issues, including inaccurate speedometer readings, compromised handling, and increased wear on suspension components. It's also important to consider the load rating of your tires. The load rating indicates the maximum weight that each tire can safely carry. Make sure that the tires you choose have a load rating that meets or exceeds the requirements for your 2019 Dodge Ram Big Horn. Overloading your tires can lead to tire failure, which can have serious consequences. In addition to load rating, also pay attention to the speed rating of your tires. The speed rating indicates the maximum speed at which the tire can safely operate. While it's unlikely that you'll be driving your truck at its maximum speed on a regular basis, it's still important to choose tires with an appropriate speed rating for your vehicle. Consulting with a tire professional can help ensure that you select tires that are properly rated for your 2019 Dodge Ram Big Horn.

In this case, the sidewall is 65% as tall as the tire is wide. The
