Understanding Tire Size Notation
If you’re looking at tire sizes and scratching your head, let’s break it down:
– 255: This number indicates the width of the tire in millimeters. A wider tire can provide better grip but may affect fuel efficiency.
– 40 or 35: This is the aspect ratio, which is the height of the tire’s sidewall as a percentage of the tire’s width. A lower number means a shorter sidewall, which can enhance handling but may lead to a harsher ride.
– R: This stands for radial, which is the most common type of tire construction.
– 18 or 19: This indicates the diameter of the wheel in inches. Larger wheels often enhance the car’s aesthetics and handling but may impact ride comfort.
Why Tire Size Matters
Choosing the right tire size is not just about aesthetics; it plays a significant role in the vehicle’s performance. Here are a few reasons why you should pay attention:
- Handling: The right tire size ensures optimal grip and handling characteristics, especially during cornering.
- Ride Comfort: The aspect ratio affects how much sidewall cushioning you have, which impacts ride comfort.
- Speedometer Accuracy: Incorrect tire sizes can throw off your speedometer readings, leading to potential legal issues.
- Fuel Efficiency: Wider tires can increase rolling resistance, affecting your fuel economy.
When it comes to the 2019 Audi S4, sticking to the stock tire sizes is generally the best route unless you’re making specific modifications for performance or aesthetic reasons. Always consult with a professional if you’re considering changing your tire size.

Smallest Tire Size: What You Need to Know
The smallest tire size that you can find for the 2019 Audi S4 is the 255/40 R18. This size is typically found on the base model. While it may seem like a standard size, it’s important to note that it offers a good balance between comfort and performance.

Cons of Smaller Tire Sizes
