OEM Tire Sizes for the 2021 Ford Ranger Lariat

So, what are the original equipment manufacturer (OEM) tire sizes for the 2021 Ford Ranger Lariat? Usually, the Lariat trim comes with a couple of different options depending on whether it's a 2WD or 4WD model, and sometimes even based on specific packages. Here’s a breakdown of the common OEM tire sizes you might find:

• 255/65R17: This is a pretty standard size you'll often see on the Lariat. The "255" refers to the tire width in millimeters, "65" is the aspect ratio (the height of the sidewall as a percentage of the width), "R" stands for radial construction, and "17" is the wheel diameter in inches. This size provides a good balance of comfort, handling, and fuel efficiency for everyday driving. It’s a solid all-around choice for most Lariat owners who primarily use their trucks for commuting and light hauling. Plus, this size offers a wide selection of tire options from various manufacturers, making it easier to find a tire that fits your budget and driving needs. For example, if you frequently drive in wet conditions, you might opt for a tire with better wet traction. Alternatively, if you prioritize fuel efficiency, you could choose a low rolling resistance tire.
• 265/60R18: You might also find this slightly larger size, especially if your Lariat has the optional wheel upgrade. Again, the "265" is the width, "60" is the aspect ratio, "R" is for radial, and "18" is the wheel diameter. This size can offer a bit more aggressive look and slightly improved handling, but it might also slightly reduce fuel economy compared to the 17-inch option. However, the 18-inch size can also enhance the overall appearance of your truck, giving it a more premium and sporty feel. Many Lariat owners choose this size for its aesthetic appeal, as it fills the wheel wells nicely and provides a more commanding presence on the road. If you often drive on rough roads or encounter potholes, the slightly larger tire can also offer a bit more cushioning and protection for your wheels.

To be absolutely sure, check the sticker on your driver’s side doorjamb. It’ll list the original tire size that came with your truck. Also, your owner's manual will have this information, plus recommended tire pressures. These are crucial details to ensure you're making the right choice when it's time for new tires.

Decoding Tire Size Numbers

Tire sizes can seem like a confusing jumble of numbers and letters, but once you understand what each component means, it becomes much easier to make informed decisions. Let's break down the typical tire size code, such as 255/65R17, to see what each part represents.

• 255 (Tire Width): The first number, in this case, "255," indicates the tire's width in millimeters at its widest point. This measurement tells you how much contact the tire makes with the road. A wider tire generally provides better grip and stability, which can be particularly useful in high-performance vehicles or trucks that frequently carry heavy loads. However, wider tires can also increase rolling resistance, potentially reducing fuel efficiency. So, choosing the right width involves balancing your need for grip with your desire for fuel economy.
• 65 (Aspect Ratio): The second number, "65," is the aspect ratio. This represents the height of the tire's sidewall as a percentage of its width. In this example, the sidewall height is 65% of the tire's width (255 mm). A lower aspect ratio means a shorter sidewall, which typically results in better handling and cornering performance. Conversely, a higher aspect ratio means a taller sidewall, which can provide a more comfortable ride and better absorption of bumps and potholes. The aspect ratio is a critical factor in determining the overall ride quality and handling characteristics of your tires.
• R (Radial Construction): The letter "R" indicates that the tire has a radial construction. Radial tires are the most common type of tire used today due to their superior durability, handling, and fuel efficiency compared to older bias-ply tires. In a radial tire, the cords that make up the tire's body run radially, or perpendicularly, from the center of the tire. This design allows the tire to flex more easily, improving ride comfort and reducing rolling resistance. Radial construction also provides better stability and longer tread life.
• 17 (Wheel Diameter): The final number, "17," is the wheel diameter in inches. This number tells you the size of the wheel that the tire is designed to fit. It's crucial to match the tire's wheel diameter to your vehicle's wheel size to ensure a proper and safe fit. Using the wrong size can lead to handling problems, tire damage, and even dangerous situations. When replacing your tires, always make sure that the new tires have the same wheel diameter as the original tires.

Understanding these components will empower you to choose the right tires for your 2021 Ford Ranger Lariat, ensuring optimal performance, safety, and comfort.

Alternate Tire Size Options

Okay, so maybe you're thinking of going a little bigger or smaller than the OEM tire sizes. That's cool, but you've gotta be careful. Here are a few things to keep in mind:

• Plus Sizing: This means increasing the wheel diameter while decreasing the tire's aspect ratio to keep the overall diameter the same. For example, you could go from a 255/65R17 to a 265/60R18. This can improve handling and give your truck a more aggressive look, but it might also make the ride a bit harsher. Plus sizing involves increasing the diameter of the wheel while simultaneously reducing the tire's sidewall height. The goal is to maintain the same overall tire diameter, so the speedometer and other vehicle systems continue to function correctly. Upgrading to a larger wheel size can enhance the vehicle's appearance and improve handling performance. However, the ride quality may become firmer due to the reduced sidewall height, which provides less cushioning.
• Minus Sizing: This is the opposite – decreasing the wheel diameter and increasing the aspect ratio. This can improve ride comfort and off-road performance, but it might make handling a bit softer. Minus sizing involves decreasing the diameter of the wheel while simultaneously increasing the tire's sidewall height. This setup is often used to improve ride comfort and off-road performance. The taller sidewall provides better absorption of bumps and rough terrain, making it ideal for off-road driving. Additionally, a smaller wheel size can sometimes reduce the cost of tires, making it an economical choice for drivers who prioritize comfort and practicality.

Before you make any changes, talk to a tire professional. They can help you find a size that fits properly without causing any problems with your truck's computer system, braking, or suspension. They can also advise you on the best tire types for your specific driving needs, whether you prioritize on-road comfort, off-road capability, or a balance of both.
