Understanding Wheel Specs

Before we get into the specifics for the 2019 Ram 1500 Big Horn, let's cover some basic wheel terminology. Understanding these terms will help you make the right choices when selecting new wheels. Knowing these basics ensures that when you're browsing through different wheel options, you'll be able to quickly identify what works and what doesn't for your specific vehicle. Plus, you'll sound like a pro when talking to the guys at the tire shop! So, let's break down the key terms you need to know.

• Diameter: This is the overall size of the wheel, measured from one end to the other through the center. It's usually measured in inches and is a critical factor when choosing new wheels because it affects the tire size you can use.
• Width: The width of the wheel is measured from one inner edge to the other, also in inches. It determines the tire's cross-sectional width that can be mounted on the wheel safely and effectively. Getting the right width is essential for maintaining proper tire performance and preventing issues like uneven wear.
• Bolt Pattern: This refers to the number and spacing of the wheel studs. It's described by two numbers, such as 5x139.7, where the first number is the number of studs and the second is the diameter of the circle they form, measured in millimeters. The bolt pattern must match your vehicle's hub for the wheel to fit correctly.
• Offset: The offset is the distance from the wheel's mounting surface to its centerline. It's measured in millimeters and can be positive, negative, or zero. The offset affects how the wheel sits in the wheel well and can impact the vehicle's handling and appearance. Choosing the correct offset is vital to avoid rubbing against the suspension or fender.
• Center Bore: This is the diameter of the hole in the center of the wheel that centers it on the vehicle's hub. It's measured in millimeters. If the center bore of the wheel matches the hub size of your vehicle, it is considered hub-centric, which is ideal for ensuring proper wheel balance and reducing vibration. If it's larger, you might need hub-centric rings to ensure a proper fit.

OEM Wheel Specs for the 2019 Ram 1500 Big Horn

So, what are the factory wheel specs for the 2019 Ram 1500 Big Horn? Knowing the original equipment manufacturer (OEM) specifications is important whether you're replacing a damaged wheel or just looking for an upgrade. Sticking to these specs ensures compatibility and maintains the vehicle's original performance and safety characteristics. Plus, it helps avoid any potential issues with warranty or insurance. Here’s what you need to know:

• Diameter: The 2019 Ram 1500 Big Horn typically comes with wheel diameters ranging from 18 to 20 inches, depending on the specific package and options. The most common size is the 18-inch wheel, which provides a good balance of ride comfort and handling.
• Width: The wheel width usually ranges from 8 to 9 inches. This width is designed to accommodate the factory-specified tire sizes, ensuring proper sidewall support and contact with the road.
• Bolt Pattern: The bolt pattern for the 2019 Ram 1500 Big Horn is 6x139.7mm (6x5.5 inches). This is a crucial specification because the replacement wheels must have the same bolt pattern to fit correctly on the vehicle's hub. Using the wrong bolt pattern can be dangerous and lead to wheel detachment.
• Offset: The offset typically ranges from +19mm to +25mm. The offset is critical because it determines how the wheel sits within the wheel well. The correct offset ensures that the tires don't rub against the suspension components or the fender.
• Center Bore: The center bore diameter is usually around 77.8 mm. Ensuring that the center bore of your new wheels matches this specification is essential for proper wheel centering and balance. If the center bore is larger, you may need to use hub-centric rings to fill the gap and ensure a snug fit.

Recommended Tire Sizes

Choosing the right tire size is just as important as the wheel specs. The tire size affects everything from ride comfort to fuel efficiency and handling. The OEM tire sizes are designed to work in harmony with the vehicle's suspension and wheel dimensions. Using the recommended tire sizes ensures that your Ram 1500 Big Horn performs optimally and safely. So, let's take a look at some of the recommended tire sizes for your truck.

• For 18-inch wheels: A common tire size is 275/65R18. This size provides a good balance of on-road comfort and off-road capability. It maintains the overall diameter close to the OEM specification, which helps preserve the accuracy of the speedometer and odometer.
• For 20-inch wheels: A typical tire size is 275/55R20. This size offers a more aggressive look and enhanced handling on paved surfaces. However, it may slightly reduce ride comfort compared to the 18-inch option.

It's also essential to consider the tire's load rating and speed rating. Make sure these ratings meet or exceed the manufacturer's specifications for the 2019 Ram 1500 Big Horn. Using tires with inadequate load or speed ratings can compromise safety and performance.

Aftermarket Wheel Options

Looking to add some personality to your Ram? Aftermarket wheels are a great way to customize the look and performance of your 2019 Ram 1500 Big Horn. But with so many options out there, it's important to choose wisely. When selecting aftermarket wheels, ensure they meet the specifications we discussed earlier: correct diameter, width, bolt pattern, offset, and center bore. Deviating from these specs can lead to fitment issues, performance problems, or even safety hazards.

• Material: You’ll find wheels made from steel, alloy, or even carbon fiber. Steel wheels are typically more affordable and durable, making them a good choice for off-roading. Alloy wheels are lighter and offer better heat dissipation, which can improve braking performance. Carbon fiber wheels are the most expensive but offer the best combination of strength and weight savings.
• Design: The design of the wheel can dramatically change the appearance of your truck. Consider factors like spoke pattern, finish, and color. Some popular styles include multi-spoke, mesh, and solid designs. The finish can range from polished to matte, and the color options are virtually endless.
• Brand Reputation: Stick with reputable brands known for quality and reliability. Research customer reviews and ratings to get an idea of the wheel's performance and durability. Brands like Fuel, Method, and Black Rhino are popular choices among truck enthusiasts.

Considerations for Upgrading

Before you make a purchase, there are a few things to keep in mind when upgrading your wheels. It’s not just about looks; you need to consider how the new wheels will affect your truck's performance and handling. Plus, there are some practical considerations to ensure a smooth and hassle-free upgrade process. So, let's cover the key considerations for upgrading your wheels.

• Load Capacity: Make sure the wheels you choose have a load capacity that meets or exceeds the requirements of your 2019 Ram 1500 Big Horn. Overloading your wheels can lead to failure, which can be extremely dangerous.
• Tire Fitment: Ensure that the tire size you plan to use is compatible with the new wheels. Consult with a tire professional to confirm the fitment and avoid any potential issues.
• Suspension Clearance: Check for adequate clearance between the wheels and suspension components. A larger or wider wheel may require modifications to the suspension or fender to prevent rubbing.
• TPMS Compatibility: If your truck is equipped with a tire pressure monitoring system (TPMS), make sure the new wheels are compatible with the sensors. You may need to purchase new sensors or have the existing ones transferred to the new wheels.
• Professional Installation: Unless you're an experienced mechanic, it's best to have your new wheels installed by a professional. This ensures that the wheels are properly mounted and torqued, which is essential for safety.

Maintaining Your Wheels

Once you've got your new wheels installed, proper maintenance is key to keeping them looking great and performing well. Regular cleaning and inspection can help prevent damage and extend the life of your wheels. Plus, well-maintained wheels enhance the overall appearance of your truck. So, let's go over some tips for maintaining your wheels.

• Regular Cleaning: Clean your wheels regularly with a mild soap and water solution. Avoid using harsh chemicals or abrasive cleaners, which can damage the finish. A soft brush or sponge is ideal for removing dirt and grime.
• Inspect for Damage: Periodically inspect your wheels for signs of damage, such as cracks, dents, or corrosion. Address any issues promptly to prevent further damage and ensure safety.
• Torque Checks: After installing or removing your wheels, re-torque the lug nuts after about 50 to 100 miles. This ensures that the wheels remain properly secured to the hub.
• Storage: If you're storing your wheels, clean them thoroughly and store them in a cool, dry place. Protect them from direct sunlight and extreme temperatures, which can cause damage.
