The Official 2021 Nissan Maxima SV Tire Size

So, what's the deal? What tire size did Nissan equip on the 2021 Maxima SV from the factory? The answer is 245/40R19. This is the tire size you'll find on most 2021 Maxima SV models. But, there's always a bit more to the story, right? While 245/40R19 is the standard, it's always a good idea to double-check the tire information sticker located on the driver's side doorjamb. This sticker is your ultimate source for the exact tire size recommended for your specific vehicle, including the correct inflation pressures. Things can sometimes vary slightly depending on the specific trim level or any optional packages your Maxima might have.

Understanding the Tire Code

Okay, let's break down that tire code: 245/40R19. It might look like gibberish at first, but each number and letter has a specific meaning:

• 245: This is the section width of the tire in millimeters. It's the width of the tire from sidewall to sidewall.
• 40: This is the aspect ratio. It's a percentage that tells you the height of the tire's sidewall compared to its width. In this case, the sidewall is 40% of the tire's width.
• R: This indicates the tire's construction. "R" stands for radial, which is the standard construction for most modern tires.
• 19: This is the wheel diameter in inches. It's the size of the wheel that the tire is designed to fit.

Knowing this breakdown empowers you to make informed decisions about your tires. This becomes crucial when you need to replace your tires. You'll know exactly what those numbers mean, making sure you select the correct size.

Why Tire Size Matters

Why is getting the right 2021 Nissan Maxima SV tire size so critical? Well, it's not just about looks, although the right tires can definitely enhance your Maxima's appearance. It has a huge impact on:

• Safety: The correct tire size ensures that your tires can properly handle the weight of your vehicle and provide optimal grip on the road. The wrong size can affect braking distances and overall handling, making your ride less safe.
• Performance: Tire size impacts acceleration, cornering, and overall performance. The right tires will allow your Maxima to perform at its best, ensuring a smooth and responsive driving experience.
• Fuel Efficiency: The size and type of tire can impact your car's fuel economy. Using the incorrect size can lead to lower gas mileage.
• Ride Comfort: The correct tires contribute to a comfortable ride by absorbing bumps and vibrations in the road.
• Accuracy of Speedometer and Odometer: Using the wrong tire size can cause your speedometer and odometer to display inaccurate readings. This could affect your ability to monitor your speed and track mileage accurately. This could also mess with your car's computer systems.

Choosing the Right Tires for Your 2021 Maxima SV

Now that you know the stock tire size, it's time to choose the perfect replacement tires. There are many tire brands and types, making the choice a little overwhelming. Let's look at the key factors to consider:

Tire Types

• All-Season Tires: These are a popular choice for their versatility, offering good performance in various weather conditions, including light snow. They're a good choice for those who experience a mix of weather conditions.
• Summer Tires: Designed for optimal performance in warm weather, summer tires provide excellent grip and handling on dry and wet roads. However, they are not recommended for use in cold temperatures or snow.
• Performance Tires: These tires are designed for high-performance driving. They offer superior grip, handling, and responsiveness, but they typically have a shorter lifespan.
• Winter Tires: Also known as snow tires, winter tires are designed to provide maximum grip and traction in snowy and icy conditions. They have a special tread pattern and rubber compound that performs well in cold weather.

Key Considerations When Choosing Tires

• Driving Conditions: Consider the weather conditions you typically drive in. Do you live in an area with heavy snow, or do you mostly drive on dry roads? This will help you narrow down the best tire type for your needs.
• Driving Style: Do you prioritize performance, or do you prefer a comfortable ride? This will influence the type of tire you choose.
• Tire Load Index and Speed Rating: Make sure the tires you choose have a load index and speed rating that meets or exceeds the original tires. This information is usually found on the sidewall of the tire. The load index indicates the maximum weight the tire can support, while the speed rating indicates the maximum speed the tire is designed to handle.
• Tire Brand and Reviews: Research different tire brands and read reviews to see what other drivers have to say about their experiences. This can help you get an idea of the tire's performance, durability, and overall value.
• Budget: Tires can range in price, so set a budget before you start shopping. Remember to factor in the cost of installation and any additional services, such as wheel balancing.

Where to Buy Tires for Your 2021 Maxima SV

You have several options for purchasing tires, including:

• Local Tire Shops: These shops offer a personalized service, including tire installation, balancing, and alignment. They can also provide expert advice on choosing the right tires for your needs.
• Online Retailers: Many online retailers offer a wide selection of tires at competitive prices. You can often have the tires shipped directly to your home or a local installer.
• Dealerships: Nissan dealerships also sell tires, but they may be more expensive than other options. However, they can ensure that you are getting the correct tires for your vehicle.

Maintaining Your Tires

Guys, once you've got your new tires, it's not set-it-and-forget-it! Proper tire maintenance is essential to extend their life and ensure your safety. Here's what you need to do:

• Check Tire Pressure Regularly: Tire pressure should be checked at least once a month, and always before long trips. You can find the recommended tire pressure on the driver's side doorjamb or in your owner's manual. Maintaining the correct tire pressure is important for fuel efficiency, handling, and tire wear.
• Inspect Tires for Wear and Damage: Regularly inspect your tires for any signs of wear and tear, such as cuts, bulges, or uneven wear. If you notice any damage, have the tires inspected by a professional.
• Rotate Your Tires: Tire rotation involves moving your tires to different positions on your vehicle to promote even wear. The recommended rotation interval is typically every 5,000 to 7,500 miles. Check your owner's manual for the recommended rotation pattern for your Maxima.
• Get Wheel Alignment: Regular wheel alignments are essential to ensure your tires wear evenly and your vehicle handles properly. Get an alignment check whenever you get new tires or if you notice any changes in handling.

Alternatives to the 245/40R19 Tire Size

While 245/40R19 is the recommended size, can you use other sizes on your 2021 Maxima SV? Technically, yes, but it is not recommended unless it's done professionally. Deviating from the factory-recommended size can affect your vehicle's performance, safety, and the accuracy of your speedometer and odometer. If you're considering a different size, it's crucial to consult with a tire professional. They can assess your specific needs and recommend a suitable alternative, ensuring it is safe and compatible with your vehicle.

Why You Shouldn't Just Guess

• Rubbing: Using a tire that's too wide or has the wrong offset can cause it to rub against the vehicle's suspension or body components. This can damage the tire and vehicle, and it can also make the car unsafe to drive.
• Speedometer Errors: Changing the tire size can affect the accuracy of your speedometer and odometer. This can lead to speeding tickets and inaccurate mileage readings.
• Handling Issues: Different tire sizes can change the handling characteristics of your vehicle. For instance, increasing the tire width can improve grip, but it can also make the steering heavier.
• Warranty Concerns: Using the wrong tire size can potentially void your vehicle's warranty. Always consult your vehicle's manual or a professional to be sure.
