2017 Nissan Altima Wheel Size

The 2017 Nissan Altima, a mainstay in the mid-size sedan segment, offers a balance of fuel efficiency, comfort, and reliability. While its exterior and interior features are often discussed, a critical, yet often overlooked, aspect is its wheel and tire specifications. These components directly influence the car's handling, ride quality, braking performance, and even its aesthetic appeal. This guide will delve into the intricacies of the 2017 Nissan Altima's wheel size, exploring the different options available, their impact on performance, and the technical considerations involved.

Understanding Wheel Size Designations

Before we delve into the specific wheel sizes for the 2017 Altima, it's crucial to understand the common nomenclature used to describe them. A typical wheel size designation might look something like "17x7J ET45 5x114.3." Let's break down each component:

Diameter: The first number, in this case "17," indicates the wheel's diameter in inches. This is the distance across the wheel where the tire sits. The 2017 Altima typically features wheel diameters ranging from 16 to 18 inches, depending on the trim level.
Width: The second number, "7," specifies the wheel's width in inches. This is the distance between the inner and outer flanges of the wheel where the tire is mounted. Wheel width is crucial for determining the appropriate tire size.
Flange Profile (J): The "J" indicates the shape of the wheel flange. This profile is standardized to ensure a secure and airtight seal between the wheel and the tire. Other common flange profiles include JJ, K, and B.
Offset (ET): "ET45" refers to the wheel offset, often denoted as ET (from the German "Einpresstiefe"). This is the distance in millimeters between the wheel's mounting surface and its centerline. A positive offset means the mounting surface is closer to the street side of the wheel, while a negative offset places it closer to the brake side. Offset significantly affects wheel fitment within the wheel well and can impact handling and suspension geometry. A larger positive offset will bring the wheel closer to the suspension components, while a smaller or negative offset will push the wheel further out.
Bolt Pattern: "5x114.3" indicates the wheel's bolt pattern. The first number, "5," signifies the number of bolts used to secure the wheel to the hub. The second number, "114.3," represents the diameter of the bolt circle in millimeters. The 2017 Altima uses a 5x114.3mm bolt pattern, which is a very common configuration.

It's essential to match the correct bolt pattern when selecting aftermarket wheels. An incorrect bolt pattern will prevent the wheel from being properly secured, leading to potentially catastrophic consequences.

2017 Altima Trim Levels and Wheel Sizes

The 2017 Nissan Altima was offered in several trim levels, each potentially featuring different wheel sizes and styles. Here's a general overview:

Altima S: Typically equipped with 16-inch steel wheels with wheel covers. These are the most basic wheels offered, prioritizing cost-effectiveness and durability. The tire size often paired with these wheels is around 215/60R16.
Altima SR: Often featured 17-inch alloy wheels with a sportier design. These wheels offer a better aesthetic appeal compared to the steel wheels and can slightly improve handling due to their lighter weight. A common tire size for the SR trim is 215/55R17.
Altima SV: Commonly came with 17-inch alloy wheels, often with a different design than the SR trim. These wheels aimed for a balance between style and comfort. The tire size is typically the same as the SR, 215/55R17.
Altima SL: The higher trim levels typically offered 17 or 18-inch alloy wheels with more intricate designs. These wheels enhanced the car's overall premium look. The tire size could be 235/45R18 for the 18-inch option.

Note: These are general guidelines, and specific wheel sizes may vary depending on optional packages or regional variations. It's always best to consult the vehicle's door jamb sticker or the owner's manual for the definitive wheel and tire specifications for your specific Altima model.

Impact of Wheel Size on Performance and Ride Quality

The wheel size directly affects several aspects of the vehicle's performance and ride quality:

Handling: Larger diameter wheels, especially when paired with wider tires, can improve handling and cornering grip. This is because they generally provide a larger contact patch with the road. However, larger wheels also increase rotational inertia, potentially making the car feel slightly slower to accelerate.
Ride Quality: Smaller diameter wheels with higher profile tires (meaning tires with a taller sidewall) tend to offer a more comfortable ride. The taller sidewall acts as an additional cushion, absorbing bumps and imperfections in the road. Larger diameter wheels with lower profile tires can transmit more road imperfections to the cabin, resulting in a firmer, and potentially harsher, ride.
Braking: Wheel size can indirectly affect braking performance. Larger wheels may allow for the installation of larger brake rotors and calipers, which can improve braking power. However, the weight of the wheels also plays a role, as heavier wheels require more energy to stop.
Fuel Efficiency: Lighter wheels generally improve fuel efficiency due to reduced rotational inertia. Larger, heavier wheels can decrease fuel economy, especially during stop-and-go driving.
Aesthetics: Wheel size and design significantly impact the vehicle's appearance. Larger wheels can give the car a more aggressive and sporty look, while smaller wheels may appear more practical and understated.

Considerations When Upgrading or Replacing Wheels

If you're considering upgrading or replacing the wheels on your 2017 Altima, there are several factors to keep in mind:

Bolt Pattern: As mentioned earlier, the bolt pattern must match the vehicle's specifications (5x114.3mm for the 2017 Altima).
Offset: Choosing the correct offset is crucial for proper wheel fitment. An incorrect offset can cause the wheels to rub against the suspension components or the fender liners. It can also negatively affect handling and stability. Consult with a reputable tire and wheel specialist to determine the appropriate offset for your desired wheel size and tire combination.
Tire Size: Selecting the correct tire size is essential for maintaining accurate speedometer readings and ensuring proper ABS and stability control function. Use online tire size calculators to determine compatible tire sizes for your chosen wheel diameter and width.
Load Rating: Ensure that the wheels you choose have a load rating that meets or exceeds the vehicle's specifications. The load rating indicates the maximum weight each wheel can safely support.
Wheel Weight: Consider the weight of the wheels, especially if you're concerned about performance or fuel efficiency. Lighter wheels can improve acceleration, braking, and fuel economy.
Professional Installation: It's always recommended to have wheels and tires installed by a qualified professional. They have the necessary tools and expertise to ensure proper installation and balancing, minimizing the risk of vibrations or other issues.

Technical Specifications and Common Problems

While exact specifications can vary, the standard wheel offset for the 2017 Altima is generally around ET45. Deviating significantly from this offset can lead to problems. A common issue encountered when upgrading wheels is tire rubbing, especially with larger diameter or wider wheels. This can be caused by an incorrect offset or the use of tires that are too wide for the wheel wells.

Another potential problem is vibration, which can be caused by improperly balanced wheels or loose lug nuts. Ensure that the wheels are properly balanced and that the lug nuts are tightened to the correct torque specification. It's also worth noting that using aftermarket wheels may sometimes require hub-centric rings. These rings fill the gap between the wheel's center bore and the vehicle's hub, ensuring a snug fit and minimizing the risk of vibration.

Finally, be aware of potential warranty implications. Installing aftermarket wheels that deviate significantly from the original specifications may void certain aspects of the vehicle's warranty, particularly those related to the suspension and braking systems. Check with your Nissan dealer for clarification.

Conclusion

Understanding the intricacies of wheel size and its impact on the 2017 Nissan Altima is crucial for maintaining its performance, ride quality, and overall safety. By considering the factors outlined in this guide, you can make informed decisions when upgrading or replacing your wheels, ensuring a proper fit and optimal performance for your vehicle. Always prioritize safety and consult with qualified professionals for expert advice.
