Hey there, Ram enthusiasts! If you're like me, you know that the wheels on your truck aren't just about getting from point A to point B; they're a statement. They define your ride's stance, performance, and overall look. Today, we're diving deep into the wheel specs for the 2019 Ram 1500 Big Horn. Whether you're looking to upgrade, replace, or just understand what you've got, this guide will cover everything you need to know. Let's get rolling!

Understanding Wheel Specs

Before we jump into the specifics for the 2019 Ram 1500 Big Horn, let's break down what wheel specs actually mean. Understanding these terms is crucial for making informed decisions about your wheels and tires.

• Diameter: This is the overall size of the wheel, measured from one end to the other through the center. It's usually expressed in inches. For instance, a 20-inch wheel has a diameter of 20 inches. The diameter affects the tire size you can use and the overall look of your truck.
• Width: The width of the wheel is measured from the inside of one flange to the inside of the opposite flange. It's also expressed in inches. The width determines the tire's section width that can be safely mounted on the wheel.
• Bolt Pattern (or Lug Pattern): This refers to the number and spacing of the wheel's bolt holes. It's crucial to match the bolt pattern of your wheels to that of your vehicle's hubs. The 2019 Ram 1500 Big Horn typically uses a specific bolt pattern, which we'll discuss in detail below.
• 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 handling and clearance.
• Center Bore: The center bore is the diameter of the hole in the center of the wheel that centers it on the vehicle's hub. It ensures the wheel is properly aligned and balanced. If the center bore of the wheel is smaller than the hub, the wheel won't fit. If it's larger, you might need hub-centric rings to ensure proper alignment.

Knowing these terms will help you navigate the world of wheels and tires with confidence. Now, let's get specific about the 2019 Ram 1500 Big Horn.

2019 Ram 1500 Big Horn: Stock Wheel Specs

The stock wheels on the 2019 Ram 1500 Big Horn are designed to provide a balance of performance, comfort, and aesthetics. Knowing the exact specifications of these wheels is essential whether you're considering replacements or upgrades. The standard wheel size for the 2019 Ram 1500 Big Horn is typically 18 inches in diameter and 8 inches in width. However, it's worth noting that different trim levels or optional packages might include variations, such as 20-inch wheels. The bolt pattern for the 2019 Ram 1500 Big Horn is 5x139.7mm (or 5x5.5 inches). This means the wheel has five lug nuts, and the distance between each lug nut is 139.7mm. Ensuring that any aftermarket wheels you consider have the same bolt pattern is crucial for a proper and safe fit.

The wheel offset for the stock wheels is usually around +19mm. This offset is designed to provide the correct balance between wheel placement within the wheel well and clearance from suspension components. The center bore for the 2019 Ram 1500 Big Horn is 77.8 mm. This ensures that the wheel sits perfectly centered on the hub, reducing the risk of vibrations and ensuring a smooth ride. When considering aftermarket wheels, it's vital to ensure that they either have the same center bore or are compatible with hub-centric rings to match this specification. Understanding these stock wheel specs is the first step in making informed decisions about your Ram 1500 Big Horn's wheels. Whether you're sticking with the factory look or planning an upgrade, having this information at your fingertips is incredibly valuable.

Bolt Pattern Explained: Why It Matters

The bolt pattern, often expressed as 5x139.7mm for the 2019 Ram 1500 Big Horn, is a critical specification for your wheels. It dictates how the wheel attaches to the vehicle's hub, ensuring a secure and balanced connection. The first number (5 in this case) indicates the number of lug nuts or bolts used to secure the wheel. The second number (139.7mm) refers to the diameter of the circle formed by the lug nut holes. This measurement is crucial because even a slight discrepancy can prevent the wheel from fitting properly. Using the wrong bolt pattern can lead to several serious issues. First and foremost, the wheel may not sit flush against the hub, which can cause vibrations and an unbalanced ride. Over time, this can damage the wheel studs and the hub itself, leading to costly repairs. More critically, if the wheel is forced onto a mismatched bolt pattern, the lug nuts may not tighten correctly. This can cause the wheel to come loose while driving, resulting in a dangerous situation.

Imagine driving down the highway and suddenly feeling a wobble – that could be a wheel about to detach! To avoid these problems, always double-check the bolt pattern before purchasing new wheels. Consult your vehicle's manual, check online databases, or ask a professional at a tire shop to confirm the correct bolt pattern for your 2019 Ram 1500 Big Horn. When shopping for aftermarket wheels, ensure the listed bolt pattern matches your vehicle's specifications exactly. Some wheels may be advertised as
