Hey guys! If you're rocking a 2019 RAM 1500 Classic, one of the most important things to keep in mind is the tire size. Getting the right tires not only ensures a smooth and safe ride but also optimizes your truck's performance. In this article, we’ll dive deep into everything you need to know about finding the perfect tire size for your RAM 1500 Classic. Let’s get started!

Understanding the Importance of Correct Tire Size

Choosing the correct tire size for your 2019 RAM 1500 Classic is crucial for several reasons. First and foremost, safety is paramount. Properly sized tires ensure that your truck handles as it should, providing the necessary grip and stability on various road surfaces. Incorrect tire sizes can lead to reduced traction, making it harder to control your vehicle, especially in adverse weather conditions. This is something you definitely don't want to compromise on, especially if you frequently drive in areas with rain, snow, or ice.

Beyond safety, the right tire size also impacts your truck's performance. The diameter of your tires affects your speedometer and odometer readings. If you deviate too far from the original equipment manufacturer (OEM) specifications, your speedometer might not accurately reflect your actual speed, and your odometer could record mileage incorrectly. This can lead to issues with fuel efficiency calculations, maintenance schedules, and even potential legal problems if your speedometer is significantly off. Imagine thinking you're driving the speed limit, only to get pulled over because your speedometer is showing a lower speed than you're actually going!

Furthermore, the tire size affects your truck's ride quality and handling. The sidewall height of the tire, which is determined by the tire size, influences how much cushioning your tires provide. Taller sidewalls generally offer a smoother ride by absorbing more of the bumps and imperfections on the road. However, they can also result in slightly less precise handling due to increased flex. Conversely, shorter sidewalls provide better handling and responsiveness but may result in a harsher ride. Finding the right balance depends on your personal preferences and the type of driving you do most often. For example, if you frequently haul heavy loads or tow trailers, you might prefer tires with stiffer sidewalls for improved stability. If you primarily use your truck for daily commuting and want a more comfortable ride, you might opt for tires with taller sidewalls. Ultimately, understanding these factors will help you make an informed decision when selecting the best tire size for your 2019 RAM 1500 Classic.

OEM Tire Sizes for the 2019 RAM 1500 Classic

The Original Equipment Manufacturer (OEM) tire sizes are what the manufacturer, in this case, RAM, originally fitted onto the vehicle when it was new. Sticking with these sizes ensures optimal performance, safety, and compatibility. For the 2019 RAM 1500 Classic, the OEM tire sizes can vary depending on the trim level and specific options your truck came with. Here's a breakdown of the common OEM tire sizes for this model:

• 265/70R17: This size is often found on the base trim levels of the 2019 RAM 1500 Classic. The '265' represents the tire width in millimeters, '70' is the aspect ratio (the ratio of the sidewall height to the tire width), 'R' indicates that it's a radial tire, and '17' is the wheel diameter in inches. These tires provide a good balance of ride comfort and handling for everyday driving.
• 275/60R20: This is another common size, often equipped on higher trim levels or models with specific wheel packages. With a wider width and a larger wheel diameter, these tires can offer enhanced stability and a more aggressive look. The lower aspect ratio (60) means a shorter sidewall, which can improve handling but might result in a slightly firmer ride compared to the 17-inch tires.
• 265/60R20: This size might also be found on some models, offering a slightly narrower width compared to the 275/60R20, but still providing the benefits of a 20-inch wheel. It can be a good option for those who want the look of larger wheels without sacrificing too much ride comfort.

To confirm the OEM tire size for your specific 2019 RAM 1500 Classic, there are a couple of reliable places to check. First, look at the sticker located on the driver's side door jamb. This sticker contains vital information about your vehicle, including the recommended tire size and inflation pressure. It's usually the most accurate source of information for your truck's original specifications. Another place to check is your owner's manual. The manual will list the recommended tire sizes for the various trim levels and configurations of the 2019 RAM 1500 Classic. By verifying the OEM tire size, you can ensure that you're selecting replacement tires that match the original specifications, maintaining the intended performance and safety characteristics of your truck. If you're considering deviating from the OEM size, it's always a good idea to consult with a tire professional to discuss the potential implications and ensure compatibility.

How to Find Your Current Tire Size

Before you start shopping for new tires, you'll need to know your current tire size. Luckily, finding this information is pretty straightforward. Just take a look at the sidewall of your tires. You'll see a series of numbers and letters that describe the tire's dimensions and specifications. Let's break down what each part of the code means:

• Tire Width: The first number you'll see represents the tire width in millimeters. For example, if the code starts with '265,' it means the tire is 265 millimeters wide.
• Aspect Ratio: The second number is the aspect ratio, which is the ratio of the tire's sidewall height to its width. It's expressed as a percentage. For instance, if the code includes '70,' it means the sidewall height is 70% of the tire width.
• Tire Construction: The letter 'R' indicates that the tire has a radial construction, which is the most common type of tire construction.
• Wheel Diameter: The last number represents the wheel diameter in inches. For example, if the code ends with '17,' it means the tire is designed to fit a 17-inch wheel.

So, a typical tire size code might look like this: 265/70R17. This tells you that the tire is 265 millimeters wide, has an aspect ratio of 70, is a radial tire, and fits a 17-inch wheel. Once you've located this code on your tire's sidewall, write it down. This is the information you'll need when searching for replacement tires. It's also a good idea to check all four tires to ensure they're the same size. While it's generally not recommended to have different size tires on the same axle, it's important to verify that all tires match to maintain proper handling and safety. If you're unsure about any of the information on your tire's sidewall, don't hesitate to consult with a tire professional. They can help you decipher the code and ensure you're selecting the correct size tires for your vehicle.

Plus Sizing and Alternative Tire Sizes

Sometimes, you might want to explore alternative tire sizes for your 2019 RAM 1500 Classic. This could be for aesthetic reasons, performance enhancements, or to accommodate different driving conditions. One common approach is "plus sizing," which involves increasing the wheel diameter while decreasing the tire's aspect ratio to maintain a similar overall diameter. For example, you might go from a 17-inch wheel to a 20-inch wheel, but you'd select a tire with a lower aspect ratio to keep the tire's overall height the same.

The main advantage of plus sizing is that it allows you to use larger, more visually appealing wheels without significantly altering your truck's speedometer readings or ride height. Larger wheels can also improve handling and stability, especially when paired with tires that have shorter sidewalls. However, it's crucial to ensure that the alternative tire size you choose is compatible with your truck and doesn't cause any rubbing or clearance issues. You'll want to check that the tires don't rub against the fenders, suspension components, or brake calipers, especially when turning or going over bumps. This is where consulting with a tire professional becomes essential.

When considering alternative tire sizes, it's also important to think about the load rating and speed rating of the tires. The load rating indicates the maximum weight that a tire can safely carry, while the speed rating indicates the maximum speed at which the tire can be driven. Make sure that the alternative tires you choose have load and speed ratings that meet or exceed the original specifications for your truck. Using tires with insufficient load or speed ratings can compromise safety and performance. Additionally, keep in mind that changing tire sizes can affect your truck's fuel efficiency, ride comfort, and handling characteristics. Larger tires may increase rolling resistance, which can reduce fuel economy. Shorter sidewalls can provide better handling but may result in a harsher ride. Ultimately, the best alternative tire size for your 2019 RAM 1500 Classic will depend on your individual needs and preferences. Weigh the pros and cons carefully, and don't hesitate to seek expert advice before making a decision.

Where to Buy Tires

Once you've determined the right tire size for your 2019 RAM 1500 Classic, the next step is to find a reputable place to buy them. You have several options to choose from, each with its own advantages and disadvantages:

• Local Tire Shops: Local tire shops are a great option because they offer personalized service and expertise. The staff can help you choose the right tires for your truck and driving needs, and they can also provide installation services. Plus, you're supporting a local business! However, prices at local tire shops may be slightly higher compared to online retailers.
• Big Box Retailers: Stores like Walmart, Costco, and Sam's Club also sell tires. They often offer competitive prices and convenient installation services. However, the selection of tires may be limited compared to dedicated tire shops, and the staff may not have as much expertise in tire selection.
• Online Retailers: Online retailers like Tire Rack and Discount Tire offer a vast selection of tires at competitive prices. You can easily compare different brands and models, read customer reviews, and have the tires shipped directly to your home or a local installer. However, you'll need to arrange for installation yourself, and you won't have the opportunity to see the tires in person before you buy them.

When choosing a retailer, consider factors such as price, selection, service, and convenience. Don't be afraid to shop around and compare prices from different retailers. Look for sales, discounts, and rebates to save money on your purchase. Also, read customer reviews to get an idea of the retailer's reputation and the quality of their service. Once you've found a retailer you trust, make sure to ask about their warranty and return policies before making a purchase. A good warranty can protect you against defects in materials or workmanship, while a flexible return policy can give you peace of mind in case you're not satisfied with your purchase. By doing your research and shopping wisely, you can find the perfect tires for your 2019 RAM 1500 Classic at a great price.
