2018 Nissan Maxima Tires

The 2018 Nissan Maxima, a popular full-size sedan, offers a blend of performance and comfort. A crucial aspect of its handling, safety, and overall driving experience is the set of tires it's equipped with. Choosing the right tires for your Maxima is paramount, and understanding the factory specifications, available options, and performance considerations is key to making an informed decision. This article delves into the world of tires for the 2018 Maxima, providing you with the technical knowledge to select the best set for your needs.

Factory Tire Specifications and OEM Options

The 2018 Nissan Maxima, depending on the trim level (S, SV, SL, SR, Platinum), typically came equipped with one of two tire sizes from the factory. These original equipment manufacturer (OEM) tires were specifically chosen to complement the vehicle's suspension and performance characteristics.

Tire Sizes:

245/45R18: This size was commonly found on the lower trim levels like the S and SV. Let's break down what this alphanumeric code means:
- 245: This is the section width of the tire in millimeters. It represents the width of the tire from sidewall to sidewall.
- 45: This is the aspect ratio, expressed as a percentage. It represents the height of the tire's sidewall as a percentage of its section width. In this case, the sidewall height is 45% of 245mm.
- R: This indicates that the tire has a radial construction. Radial tires are the most common type of tire construction used today, characterized by the cords running radially across the tire from bead to bead.
- 18: This is the wheel diameter in inches. It indicates the size of the wheel the tire is designed to fit.
245/40R19: This size was typically found on the higher trim levels, such as the SR and Platinum, offering a slightly sportier appearance and potentially sharper handling. The breakdown is similar to the 18-inch tire, except for the aspect ratio (40) and the wheel diameter (19 inches). The lower aspect ratio signifies a shorter sidewall, generally contributing to improved cornering stability.

OEM Tire Brands and Models:

Nissan often partners with major tire manufacturers to provide OEM tires. Common brands that may have been fitted on the 2018 Maxima include:

Goodyear: Models like the Eagle Touring or similar grand touring tires.
Bridgestone: Models like the Turanza EL400 or similar touring tires.
Hankook: Ventus S1 noble2 being a possible selection.

These OEM tires are often designed to provide a balance of performance, ride comfort, and longevity. They are rigorously tested to meet Nissan's specific requirements. However, you are not limited to these brands when replacing your tires.

Understanding Tire Performance Categories

When selecting replacement tires, it's crucial to understand the different performance categories to match your driving style and needs. Here are some common categories:

Touring Tires: These tires offer a good balance of ride comfort, handling, and tread life. They are designed for everyday driving and long-distance cruising. They often have lower rolling resistance, contributing to better fuel economy.
Performance Tires: These tires prioritize handling and grip, providing enhanced responsiveness and cornering capabilities. They often have a stickier tread compound, but may have shorter tread life and ride more firmly than touring tires. Subcategories include:
- Summer Performance Tires: Designed for optimal grip in warm, dry conditions. Not suitable for cold weather or snow.
- All-Season Performance Tires: Offer a compromise between summer and winter performance, providing decent grip in a variety of conditions.
All-Season Tires: The most versatile option, offering decent performance in a variety of weather conditions, including light snow. They are a good choice for drivers who experience moderate winters.
Winter Tires: Designed specifically for cold weather and snowy/icy conditions. They have a specialized tread pattern and rubber compound that provides superior grip in winter conditions. Using winter tires significantly improves safety in cold climates.

Key Considerations for Tire Selection

Several factors should be considered when choosing replacement tires for your 2018 Maxima:

Driving Style: Do you prioritize comfort and fuel economy or sporty handling and performance? A touring tire might suit the former, while a performance tire would be better for the latter.
Climate: Do you live in an area with severe winters? If so, winter tires are a necessity. If you experience moderate winters, all-season tires might be sufficient.
Tread Life: Consider the expected tread life of the tires. Some performance tires have shorter tread life due to their softer rubber compound. The UTQG (Uniform Tire Quality Grading) treadwear rating can provide a relative indication of tread life, but it's important to remember that it's just a guideline.
Budget: Tire prices can vary significantly depending on the brand, model, and performance category. Set a budget and research tires within that range.
Noise Level: Some tires are quieter than others. Read reviews to get an idea of the noise level of different tires.
Load Index and Speed Rating: These are critical numbers molded into the tire's sidewall. They indicate the maximum load the tire can carry and the maximum speed it can safely handle. Always choose tires with a load index and speed rating equal to or greater than the original equipment specifications for your vehicle. Exceeding the tire's load capacity or speed rating can lead to tire failure and accidents. You can find the OEM specifications on the sticker located on the driver's side door jamb.

Plus Sizing and Alternative Tire Options

Plus sizing involves increasing the wheel diameter and decreasing the aspect ratio to maintain a similar overall tire diameter. This can improve handling and appearance. While possible, it's crucial to ensure that the new tire size doesn't cause clearance issues with the suspension components or fender wells. Consult with a tire professional to determine if plus sizing is appropriate for your Maxima. Generally, deviating significantly from the OEM tire sizes can affect speedometer accuracy and anti-lock braking system (ABS) performance.

It's also essential to use an online tire size calculator. These calculators help visualize the differences in diameter, width, and sidewall height between tire sizes. They will also show you the percentage difference in speedometer readings, which is a crucial element to keep an eye on. Keeping the overall diameter within +/- 3% of the OEM tire is advisable to avoid these issues.

Tire Pressure Monitoring System (TPMS)

The 2018 Nissan Maxima is equipped with a Tire Pressure Monitoring System (TPMS). This system alerts the driver when tire pressure is low. When replacing tires, it's important to ensure that the TPMS sensors are properly installed and functioning correctly. Some tire shops offer TPMS service, including sensor replacement and programming. Neglecting the TPMS can lead to inaccurate readings and potential safety issues.

Remember that TPMS sensors have a limited lifespan, as the battery inside will eventually die. It's usually advisable to replace them every 5-7 years, or when changing tires, to avoid having to pay for remounting and balancing later on.

Tire Maintenance

Proper tire maintenance is crucial for extending tire life and ensuring safe driving. Key maintenance practices include:

Regularly check tire pressure: Use a reliable tire pressure gauge and maintain the recommended tire pressure, which can be found on the sticker on the driver's side door jamb. Check when the tires are cold (before driving).
Rotate tires: Rotate your tires every 5,000-7,000 miles to ensure even wear. This helps to prolong the life of your tires.
Inspect tires for wear and damage: Regularly inspect your tires for signs of wear, such as uneven wear patterns, bulges, or cuts. Replace tires when the tread depth reaches the minimum legal limit (typically 2/32 inch).
Wheel Alignment: Proper wheel alignment is essential for even tire wear and optimal handling. Have your wheels aligned if you notice uneven tire wear or if the vehicle pulls to one side.

By understanding the factory tire specifications, performance categories, and key considerations for tire selection, you can choose the best tires for your 2018 Nissan Maxima. Remember to prioritize safety, performance, and your individual driving needs to make an informed decision and enjoy a safe and comfortable driving experience. Always consult a qualified tire professional if you have any questions or need assistance.
