Nissan Altima 2013 Wheel Size

The 2013 Nissan Altima marked a significant year in the model's history, representing the first year of its fifth generation (L33). A crucial aspect often overlooked, yet essential for performance, aesthetics, and safety, is the vehicle's wheel and tire configuration. This article delves into the wheel sizes, tire specifications, and related considerations for the 2013 Nissan Altima.

2013 Nissan Altima Wheel Size Options

The 2013 Altima wasn't a one-size-fits-all affair when it came to wheels. Nissan offered various trim levels, each sometimes sporting different wheel sizes and designs. The most common wheel sizes you'd find on a 2013 Altima were:

16-inch Wheels: Typically found on the base S and SV models. These offered a comfortable ride and better fuel economy due to the increased tire sidewall.
17-inch Wheels: Often equipped on higher-trim SV and SL models. These struck a balance between ride comfort and handling performance.
18-inch Wheels: Available on the sportier SR trim and as an option on some SL models. These wheels provided a more aggressive look and improved handling, but with a slightly firmer ride.

It's important to verify the exact wheel size on a specific vehicle, as options and regional variations could exist. The easiest way to confirm is to check the tire placard located on the driver's side doorjamb. This sticker contains vital information, including the original equipment (OE) tire size and recommended inflation pressure.

Understanding Wheel Specifications

Beyond just the diameter, several other specifications define a wheel. These include:

Width: Measured in inches, this indicates the width of the wheel's rim where the tire sits. For example, a 16x7 wheel is 16 inches in diameter and 7 inches wide.
Bolt Pattern (PCD): This refers to the number of lug nuts and the diameter of the circle they form. The 2013 Altima uses a 5x114.3mm (also expressed as 5x4.5") bolt pattern. This is a very common bolt pattern across many Japanese and some American vehicles.
Offset (ET): Measured in millimeters, offset is the distance between the wheel's mounting surface and its centerline. A positive offset means the mounting surface is closer to the outside of the wheel, while a negative offset means it's closer to the inside. The correct offset is crucial for proper wheel fitment and suspension geometry. Deviation from the original offset can impact handling, tire wear, and even potentially damage suspension components. The 2013 Altima generally uses an offset in the range of ET40 to ET50 depending on the wheel width.
Center Bore (CB): This is the diameter of the hole in the center of the wheel that centers it on the vehicle's hub. For the 2013 Altima, the center bore is 66.1mm. Using wheels with the correct center bore ensures proper wheel centering and prevents vibration. If using aftermarket wheels with a larger center bore, hub-centric rings should be used to ensure proper fitment.

Tire Specifications for the 2013 Nissan Altima

The tire size is intrinsically linked to the wheel size. Here’s a breakdown of the typical tire sizes used on the 2013 Altima, corresponding to the wheel sizes:

16-inch Wheels: Generally paired with P215/60R16 tires. The "P" indicates a passenger tire, 215 is the tire width in millimeters, 60 is the aspect ratio (sidewall height as a percentage of the width), and R16 denotes a radial tire with a 16-inch diameter.
17-inch Wheels: Usually fitted with P215/55R17 tires. Notice the change in aspect ratio to maintain a similar overall tire diameter.
18-inch Wheels: Typically equipped with P235/45R18 tires. The wider tire provides a larger contact patch for improved grip.

Beyond size, tire specifications also include load index and speed rating. These are crucial for safety. The load index indicates the maximum weight each tire can carry, while the speed rating indicates the maximum speed at which the tire can safely operate. Consult the tire placard on your vehicle for the recommended load index and speed rating.

Tire Pressure Monitoring System (TPMS)

The 2013 Altima is equipped with a Tire Pressure Monitoring System (TPMS). This system monitors the tire pressure in each tire and alerts the driver if the pressure drops below a certain threshold. When replacing wheels or tires, it's essential to ensure that the TPMS sensors are properly installed and functioning correctly. Many aftermarket wheels require specific TPMS sensors. Ignoring the TPMS can lead to inaccurate readings and potentially unsafe driving conditions. A malfunctioning TPMS can also trigger warning lights on the dashboard and fail vehicle inspections.

Aftermarket Wheel and Tire Options

Many Altima owners choose to upgrade their wheels and tires for aesthetic or performance reasons. When considering aftermarket options, it’s crucial to ensure proper fitment. Using online tools and consulting with reputable tire shops can help avoid potential issues such as:

Fender Rubbing: Using wheels or tires that are too wide or have an incorrect offset can cause them to rub against the fenders, especially during turns or when the suspension is compressed.
Suspension Interference: Wheels or tires that are too large can interfere with suspension components, limiting suspension travel and potentially damaging parts.
Brake Caliper Clearance: Certain aftermarket wheels may not clear the brake calipers, preventing them from being installed.
Altered Handling: Changing wheel and tire sizes can significantly impact the vehicle's handling characteristics. It’s important to choose options that are compatible with the vehicle's suspension and intended use.

When selecting aftermarket wheels, ensure they are load-rated appropriately for the vehicle. Using wheels with a lower load rating than required can compromise safety and potentially lead to wheel failure.

Maintenance and Longevity

Proper maintenance is essential for maximizing the life of your wheels and tires. Regular tire rotations (every 5,000-7,000 miles) help ensure even wear. Maintaining proper tire pressure, as specified on the tire placard, is crucial for fuel economy, tire life, and handling. Inspect your tires regularly for signs of wear and damage, such as:

Uneven Wear: Indicates potential alignment or suspension issues.
Bulges or Sidewall Cracks: Can lead to sudden tire failure.
Low Tread Depth: Reduces traction, especially in wet conditions.

Damaged wheels should be repaired or replaced promptly. Bent or cracked wheels can compromise safety and negatively impact handling. Periodically cleaning your wheels will also help prevent corrosion and maintain their appearance.

Common Problems and Considerations

While the 2013 Altima is generally reliable, there are some wheel and tire-related issues to be aware of:

TPMS Sensor Failures: TPMS sensors can fail due to corrosion, battery depletion, or physical damage. Replacement sensors can be costly.
Wheel Bearing Wear: Worn wheel bearings can cause noise and vibration, especially at higher speeds. Ignoring worn wheel bearings can lead to more serious damage and even wheel separation.
Alignment Issues: Misalignment can cause uneven tire wear and negatively impact handling. Regular alignment checks are recommended, especially after hitting potholes or curbs.

When replacing tires, consider the climate and driving conditions in your area. All-season tires are a good compromise for most drivers, but those in areas with heavy snow may want to consider winter tires for improved traction.

Conclusion
