The tire size for your Nissan Altima depends heavily on the model year and trim level. There's no single answer, so let's break down how to find the precise tire size for your specific vehicle. Knowing your tire size is crucial for safe and proper vehicle operation. Using the incorrect size can impact handling, fuel economy, and even your speedometer accuracy.

Finding Your Nissan Altima's Tire Size: A Step-by-Step Guide

The easiest way to determine your Altima's tire size is to check the following locations:

1. The Driver's Side Doorjamb: This sticker usually details the recommended tire size, tire pressure, and other vital vehicle information. Look for a sticker on the driver's side doorjamb, often near the latch. This is the most reliable source.

2. Your Owner's Manual: The owner's manual provides detailed specifications for your vehicle, including the recommended tire size.

3. The Tire Sidewall: The tire size is printed directly on the sidewall of each tire. This information is often presented in a format like P215/60R17 or similar. We'll break down what this means below.

4. Your Vehicle's Tire Information Plate: Some models have a plate located under the hood or in the trunk that provides tire specifications.

Understanding Tire Size Numbers

Let's decode the typical tire size designation, for example, P215/60R17:

• P: Indicates the tire is for a passenger vehicle.
• 215: This is the tire's width in millimeters.
• 60: This represents the aspect ratio—the tire's height as a percentage of its width. A 60 aspect ratio means the tire's height is 60% of its 215mm width.
• R: Indicates a radial tire construction (almost all modern tires are radial).
• 17: This is the wheel diameter in inches.

Example: A P215/60R17 tire is 215mm wide, has a height that is 60% of its width, and fits a 17-inch wheel.

Common Nissan Altima Tire Sizes

While the specific size varies by year and trim, some common tire sizes for Nissan Altimas include:

• P215/60R17: A very common size across multiple model years.
• P215/55R18: Often found on higher trim levels or later model years.
• 235/45R18: Found on some sportier trims.
• P235/40R19: Seen on some higher-end models.

Important Note: Always consult your owner's manual or the sticker on your driver's side doorjamb for the specific tire size recommended for your Nissan Altima. Using the wrong size can negatively affect your vehicle's performance and safety.

What if I want to change my tire size?

Changing tire size is possible, but it's essential to consider the implications. Larger tires might affect your speedometer calibration, potentially leading to inaccurate readings. Smaller tires might increase your engine RPM at highway speeds. Always consult a tire professional before making changes to ensure compatibility with your vehicle and to avoid potential issues. They can help you determine which tire sizes are safe and appropriate for your Altima.

Ultimately, finding the correct tire size for your Nissan Altima is crucial for safety, performance, and compliance. Remember to always consult your owner's manual or the sticker on your driver's side doorjamb for the most accurate information.
