Hey guys! If you're wondering about the right tire size for your 2020 Subaru Forester, you've come to the right place. Choosing the correct tire size is super important for your vehicle's performance, safety, and overall driving experience. 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, think of it like wearing the right shoes. If they're too big or too small, you're not going to have a good time. Similarly, the wrong tire size can mess with your car's handling, fuel efficiency, and even the accuracy of your speedometer. Using the correct tire size ensures optimal performance and safety.

First off, the right tire size directly impacts your vehicle's handling. When your tires are the size that the manufacturer intended, your car responds predictably to your steering inputs. This predictability is crucial, especially in emergency situations where quick maneuvering is required. Imagine trying to swerve to avoid an obstacle with tires that are too large or too small; the car might not respond as expected, leading to a potentially dangerous situation.

Secondly, your car's fuel efficiency is closely tied to tire size. The rolling resistance of the tires—how much energy they need to move—affects how hard your engine has to work. The correct tire size ensures that the rolling resistance is optimized for your vehicle, helping you save money at the gas pump. Overinflating tires reduces the amount of tire surface area touching the road, which lowers rolling resistance; underinflating them increases it. Either way, you'll get worse gas mileage, but too little air in the tires also creates unsafe driving conditions. In addition, tires that are too large can increase rolling resistance, while tires that are too small might not provide enough grip, both negatively impacting fuel economy.

Finally, the accuracy of your speedometer and odometer depends on the correct tire size. These systems are calibrated to work with a specific tire size, and changing that size can throw them off. This means that if you have the wrong size tires, your speedometer might show that you're driving slower or faster than you actually are, and your odometer won't accurately track the distance you've traveled. This can lead to speeding tickets or incorrect maintenance schedules, both of which are easily avoided by using the right tire size. Ensuring that your speedometer and odometer are accurate is important for legal and practical reasons.

OEM Tire Size for the 2020 Subaru Forester

The Original Equipment Manufacturer (OEM) tire size for the 2020 Subaru Forester is typically 225/60R17 or 225/55R18, depending on the trim level. Always double-check the sticker on your driver's side doorjamb to confirm the exact size recommended for your specific vehicle. This sticker contains essential information, including the correct tire size and recommended tire pressure. Sticking to the OEM size ensures that your Forester performs as the engineers intended.

Understanding the tire size code can seem a bit daunting at first, but it’s actually quite straightforward once you break it down. Let's take the 225/60R17 tire size as an example:

• 225: This number indicates the tire's section width in millimeters. In this case, the tire is 225 millimeters wide from sidewall to sidewall.
• 60: This is the aspect ratio, which represents the height of the tire's sidewall as a percentage of its width. Here, the sidewall height is 60% of the tire's width.
• R: This letter signifies that the tire has a radial construction, which is the most common type of tire construction.
• 17: This number is the diameter of the wheel in inches. This tire is designed to fit a 17-inch wheel.

Different trim levels of the 2020 Subaru Forester may come with slightly different tire sizes. For instance, higher trim levels often feature larger wheels, which necessitate a different tire size to maintain the overall rolling diameter. It's crucial to check the sticker on your doorjamb to get the precise OEM tire size for your specific trim level. Tire manufacturers and retailers will also provide fitment guides that can help you determine the correct tire size for your vehicle. These guides take into account the year, make, model, and trim level of your car to ensure that you get the right tires. Ignoring these recommendations can lead to performance issues and potential safety hazards.

How to Find the Tire Size on Your Vehicle

Finding the tire size on your vehicle is a straightforward process. The easiest way is to check the driver's side doorjamb. There, you'll find a sticker that lists the original equipment tire size and recommended tire pressure. You can also find the tire size printed on the sidewall of your current tires. Look for a series of numbers and letters, such as 225/60R17. This will tell you the width, aspect ratio, and wheel diameter.

If you're having trouble locating the tire size information, you can consult your vehicle's owner's manual. The manual typically contains a comprehensive list of specifications, including the recommended tire size for your car. Alternatively, you can use online resources such as tire size calculators and fitment guides. These tools allow you to enter your vehicle's year, make, and model to find the correct tire size.

Another great resource is a local tire shop. Tire professionals can quickly identify the correct tire size for your vehicle and provide recommendations based on your driving needs and preferences. They can also help you understand the different tire options available and explain the pros and cons of each. Remember, correctly identifying your tire size is the first step in ensuring optimal performance and safety.

Plus Sizing and Alternative Tire Sizes

Okay, so what about plus sizing? Plus sizing involves increasing the wheel diameter while decreasing the tire's sidewall height to maintain the same overall diameter. For example, you might go from a 17-inch wheel to an 18-inch wheel. The main reason people do this is for aesthetic purposes, as larger wheels can enhance the vehicle's appearance. Plus sizing can also improve handling by reducing the tire's sidewall flex. However, it's essential to ensure that the alternative tire size doesn't cause rubbing or interfere with the suspension components.

When considering alternative tire sizes, it's important to stay within 3% of the original tire's overall diameter. This ensures that your speedometer and odometer remain accurate. You can use online tire size calculators to compare different tire sizes and determine their overall diameter. These calculators will also show you the difference in diameter between the original tire size and the alternative size. If the difference exceeds 3%, it's best to stick with the OEM size.

Before making any changes, consult with a tire professional. They can provide expert advice and help you choose an alternative tire size that meets your needs without compromising safety or performance. They can also ensure that the new tires fit properly and don't cause any issues. Keep in mind that deviating too far from the original tire size can negatively impact your vehicle's handling, fuel economy, and speedometer accuracy.

Choosing the Right Tire for Your Needs

Choosing the right tire isn't just about size; it's also about the type of tire. Different tires are designed for different driving conditions and purposes. For example, all-season tires are a popular choice for the Subaru Forester because they offer a good balance of performance in various weather conditions. They provide decent traction in both dry and wet conditions, making them suitable for year-round use. However, they may not perform as well as dedicated winter tires in heavy snow or ice.

Winter tires, on the other hand, are specifically designed for cold weather and snowy conditions. They have a special rubber compound that stays flexible in low temperatures, providing superior grip on ice and snow. If you live in an area with harsh winters, winter tires are a worthwhile investment. They can significantly improve your vehicle's handling and braking performance in winter conditions.

For those who enjoy off-roading, all-terrain tires are a great option. These tires have a more aggressive tread pattern that provides better traction on dirt, gravel, and other uneven surfaces. They are designed to withstand the rigors of off-road driving and offer enhanced durability. However, they may produce more road noise and have lower fuel efficiency compared to all-season tires. Selecting the right tire type depends on your individual driving needs and the conditions you typically encounter.

Maintaining Your Tires for Longevity

Once you've got the right tires, maintaining them properly is key to extending their lifespan and ensuring optimal performance. Regularly checking your tire pressure is one of the most important things you can do. Use a reliable tire pressure gauge to check the pressure at least once a month, and always inflate your tires to the recommended pressure listed on the driver's side doorjamb. Underinflated tires can wear out prematurely and reduce fuel efficiency, while overinflated tires can lead to a harsh ride and uneven wear.

In addition to checking tire pressure, it's important to rotate your tires regularly. Tire rotation involves moving the tires from one position to another on the vehicle to ensure even wear. The recommended rotation pattern varies depending on the vehicle and tire type, so consult your owner's manual or a tire professional for guidance. Tire rotation can help extend the life of your tires and maintain consistent handling.

Finally, be sure to inspect your tires regularly for any signs of damage, such as cuts, bulges, or uneven wear. If you notice any issues, have your tires inspected by a professional. Addressing problems early can prevent them from becoming more serious and potentially dangerous. Proper tire maintenance is essential for safety and longevity.
