Finding the right tire size for your Nissan Altima SR is crucial for optimal performance, safety, and handling. This guide will provide you with all the information you need to ensure you're using the correct tires for your vehicle.

Standard Tire Size for the Nissan Altima SR
The standard tire size for most model years of the Nissan Altima SR is 215/55R17. However, it's absolutely critical to verify this information. Different model years and even trim levels within the SR might have variations. Always check your vehicle's specifications.
Where to Find Your Tire Size Information:
- Your Driver's Side Doorjamb: This is the most reliable location. The sticker usually lists the recommended tire size, along with other important vehicle information.
- Your Owner's Manual: The owner's manual provides comprehensive details about your vehicle, including tire specifications.
- The Tire Sidewall: The tire itself will have the size printed on the sidewall. This is useful if you're already looking at a tire, but remember, this is the current tire size, not necessarily the recommended size.
