Hey guys! Are you trying to figure out the right tire size for your 2018 Subaru WRX Premium? You've come to the right place! Getting the correct tire size is super important for your car's performance, safety, and overall driving experience. In this article, we're going to dive deep into everything you need to know about the 2018 Subaru WRX Premium tire sizes, making sure you get the perfect fit for your ride. Let's get started!

Understanding the Importance of Correct Tire Size

So, why does tire size matter so much? Well, think of it like shoes – too big or too small, and you're going to have a bad time. Here’s why getting the right tire size is crucial:

• Performance: Correctly sized tires ensure your WRX handles the way it’s supposed to. The right tires provide optimal grip, braking, and acceleration. If you're running on the wrong size, you might notice a decrease in handling precision, which can be a bummer, especially if you enjoy those sharp turns and quick maneuvers. Imagine trying to run a marathon in flip-flops – not ideal, right? The same goes for your car; the right tires are essential for peak performance.
• Safety: Tires are your car's direct connection to the road. Using the wrong size can compromise your vehicle's safety features, such as the anti-lock braking system (ABS) and electronic stability control (ESC). These systems are calibrated to work with specific tire sizes. Slapping on the wrong set can throw everything off, increasing your risk of accidents. Safety should always be a top priority, and the right tires play a huge role in ensuring that.
• Fuel Efficiency: Believe it or not, tire size can affect your gas mileage. Using tires that are too large or too small can increase rolling resistance, which means your engine has to work harder to move the car. This can lead to a noticeable decrease in fuel efficiency over time. Sticking with the recommended tire size helps maintain optimal fuel economy, saving you money at the pump. Plus, who doesn’t want to save a few extra bucks on gas?
• Accuracy of Speedometer and Odometer: Your car's speedometer and odometer are calibrated based on the original tire size. When you switch to a different size, it can throw off these readings. This means you might think you're driving the speed limit, but you're actually going faster (or slower). Similarly, your odometer might not accurately reflect the miles you've driven, which can affect your car's resale value and maintenance schedule. Keeping the correct tire size ensures these readings remain accurate.
• Ride Comfort: The right tire size contributes to a comfortable ride. Using tires that are too big can make your ride harsh and bumpy, while tires that are too small might not provide enough cushioning. The recommended tire size is designed to balance performance and comfort, giving you the best of both worlds. After all, you want to enjoy your time behind the wheel, not feel like you're riding a bucking bronco.

Recommended Tire Size for the 2018 Subaru WRX Premium

Okay, let's get down to brass tacks. For the 2018 Subaru WRX Premium, the standard tire size is 235/45R17. This means:

• 235: The width of the tire in millimeters.
• 45: The aspect ratio (the height of the sidewall as a percentage of the width).
• R17: The diameter of the wheel in inches.

Sticking with this size will ensure your WRX performs as intended. However, there are a few alternative sizes you might consider, depending on your specific needs and preferences. Just remember to check that any alternative sizes are compatible with your vehicle to avoid any potential issues.

Understanding Tire Size Markings

Ever looked at your tires and wondered what all those numbers and letters mean? Let's break it down so you can confidently decipher tire markings:

• Tire Width (235 in our example): This is the width of the tire measured in millimeters from sidewall to sidewall. A wider tire generally provides more grip but can also increase rolling resistance.
• Aspect Ratio (45 in our example): This is the height of the tire’s sidewall expressed as a percentage of its width. A lower aspect ratio (like 45) means a shorter sidewall, which can improve handling but may result in a harsher ride. A higher aspect ratio means a taller sidewall, offering more comfort but potentially reducing handling precision.
• Wheel Diameter (R17 in our example): This is the diameter of the wheel that the tire is designed to fit, measured in inches. It's crucial to match the tire's wheel diameter to your car's wheel size to ensure a proper fit.
• Load Index: This number indicates the maximum weight each tire can support when properly inflated. Always ensure your tires have a load index that meets or exceeds your vehicle's requirements.
• Speed Rating: This letter indicates the maximum speed at which the tire is designed to be driven for extended periods. Again, make sure your tires have a speed rating that matches or exceeds your vehicle's capabilities.

Understanding these markings will help you make informed decisions when it's time to replace your tires.

Factors to Consider When Choosing Tires

Choosing the right tires isn't just about size; it's also about considering your driving habits and local weather conditions. Here are some factors to keep in mind:

• Driving Conditions: Do you mostly drive in the city, on the highway, or off-road? Different tires are designed for different types of driving. For example, if you do a lot of highway driving, you might want to consider tires with a higher speed rating and better fuel efficiency. If you frequently drive in snowy or icy conditions, winter tires are a must. Understanding your typical driving conditions will help you narrow down your options.
• Weather Conditions: If you live in an area with harsh winters, you'll definitely want to invest in winter tires. These tires have a special tread pattern and rubber compound that provide superior grip on snow and ice. If you live in a warmer climate, all-season tires might be a better choice. They offer a good balance of performance in both wet and dry conditions. Consider your local weather conditions to ensure you have the right tires for the job.
• Tire Type: There are several types of tires to choose from, including all-season, summer, winter, and performance tires. Each type has its own unique characteristics and is designed for specific purposes. All-season tires are a versatile option that works well in a variety of conditions. Summer tires offer excellent grip and handling in warm weather. Winter tires provide superior traction in snow and ice. Performance tires are designed for high-speed driving and offer enhanced handling capabilities. Choose the tire type that best suits your driving needs and preferences.
• Budget: Tires can range in price from budget-friendly to high-end. While it's tempting to go for the cheapest option, it's important to consider the long-term costs. Cheaper tires might not last as long or perform as well as more expensive ones. Investing in quality tires can save you money in the long run by providing better fuel efficiency, longer tread life, and improved safety. Set a budget and look for tires that offer the best value for your money.

Where to Find the Right Tires

Finding the right tires for your 2018 Subaru WRX Premium is easier than you might think. Here are some places to check out:

• Local Tire Shops: These shops often have knowledgeable staff who can help you find the right tires for your car. They can also provide installation services and answer any questions you might have. Supporting local businesses is always a plus!
• Online Retailers: Websites like Tire Rack and Discount Tire offer a wide selection of tires at competitive prices. You can easily compare different brands and models, read reviews, and have the tires shipped directly to your door. Just make sure you know your car's tire size and other specifications before you start shopping.

They might offer tires that are specifically designed for your car and can provide expert installation services. Plus, they can ensure that the tires meet Subaru's standards for performance and safety.

Installation and Maintenance Tips

Once you've found the perfect tires, it's important to have them installed correctly and maintain them properly. Here are a few tips to keep in mind:

• Professional Installation: Unless you're a seasoned mechanic, it's best to have your tires installed by a professional. They have the tools and expertise to ensure the tires are properly mounted and balanced. This will help prevent premature wear and ensure a smooth ride.
• Regular Tire Rotation: Rotating your tires every 5,000 to 7,000 miles can help them wear evenly and extend their lifespan. Tire rotation involves moving the tires from one position on the car to another, following a specific pattern. Check your owner's manual for the recommended rotation pattern for your vehicle.
• Proper Inflation: Maintaining the correct tire pressure is crucial for safety, fuel efficiency, and tire life. Check your tire pressure regularly (at least once a month) and inflate your tires to the recommended pressure listed in your owner's manual or on the sticker inside your driver's side door. Use a reliable tire pressure gauge to ensure accurate readings.
• Wheel Alignment: A proper wheel alignment ensures that your tires are pointing in the right direction. Misalignment can cause uneven tire wear, poor handling, and reduced fuel efficiency. Have your wheel alignment checked periodically, especially if you notice your car pulling to one side or your tires wearing unevenly.
