Understanding Tire Size Notation
The tire size notation can seem confusing, but it’s pretty straightforward once you break it down. For example, in the size 225/50R18:
– 225 refers to the tire width in millimeters.

– R indicates that the tire is of radial construction.
– 18 is the diameter of the wheel in inches.
Why Tire Size Matters
Choosing the right tire size is not just about aesthetics; it affects various aspects of your vehicle’s performance:
- Handling: Wider tires can improve grip and handling, especially in corners.
- Ride Comfort: The right sidewall height can absorb bumps better, leading to a smoother ride.
- Fuel Efficiency: Incorrect tire sizes can lead to increased rolling resistance, affecting your fuel economy.
- Speedometer Accuracy: Using the wrong size can throw off your speedometer readings.

Exploring the Smallest and Biggest Tire Sizes for the 2015 Altima SL
When it comes to the 2015 Nissan Altima SL, tire size plays a pivotal role in how your vehicle performs on the road. While the stock tire size is 225/50R18, many owners have explored alternatives, either for performance upgrades or to address specific driving conditions. Let’s break down the smallest and biggest tire sizes that can be fitted on the Altima SL, along with some insights from forums and owner feedback.
Smallest Tire Size Options
For those looking to downsize from the stock 225/50R18 tires, the smallest compatible size is generally 215/55R17. This size offers a few benefits and trade-offs:
- Improved Ride Comfort: The smaller diameter can provide a softer ride due to a taller sidewall.
- Cost-Effective: 17-inch tires are often cheaper than 18-inch options, which can save you money during replacements.
- Better Winter Performance: A narrower tire can cut through snow better, making it a good choice for winter driving.
However, downsizing also comes with some drawbacks:
- Reduced Handling Precision: A smaller tire may not grip the road as well during high-speed maneuvers.
- Speedometer Calibration: Switching to a smaller tire size can affect your speedometer accuracy, so be aware of that.
Owner Feedback on Smaller Tires
Many owners who switched to the 215/55R17 size have reported a noticeable improvement in ride comfort. However, some have mentioned that the handling feels a bit less sharp compared to the stock tires. Forums often highlight brands like Michelin and Continental as reliable choices for this size, with users praising their longevity and performance in various weather conditions.
Biggest Tire Size Options
On the flip side, if you are looking to upsize your tires for a more aggressive stance or enhanced performance, you might consider going up to a size like 235/45R18. This option provides a broader contact patch, which can enhance grip and cornering stability.
- Enhanced Grip: A wider tire can improve traction, especially during spirited driving.
- Aggressive Look: Upsizing can give your Altima a more aggressive and sporty appearance.
- Better Performance on Dry Roads: Wider tires tend to perform better in dry conditions.
However, upsizing also has its pitfalls:
- Reduced Fuel Efficiency: Wider tires can increase rolling resistance, potentially lowering your fuel economy.
- Increased Road Noise: Some users report that wider tires can generate more road noise.
- Potential for Rubbing: Depending on your Altima’s suspension setup, larger tires may rub against the fender wells during turns or bumps.

Drivers who have opted for the 235/45R18 size often rave about the improved handling and sporty feel. Many forum discussions highlight brands like Goodyear and Bridgestone as top choices for this size, with users noting enhanced performance in both dry and wet conditions. However, some have cautioned about the trade-offs in fuel efficiency and potential noise increase.
