The 2018 Audi S5 Sportback is offered in a couple of trims, and each trim has its own set of specifications for tire size. Here’s a quick rundown:

Understanding the Tire Size Notation
The tire size notation can seem confusing at first glance, but breaking it down helps. For example, in the tire size 255/40 R18:
– **255**: This number represents the tire width in millimeters. A wider tire can provide better grip.
– **40**: This is the aspect ratio, which is the height of the sidewall as a percentage of the width. A lower number means a shorter sidewall, which can enhance handling.
– **R**: This indicates that the tire is of radial construction, which is standard for modern vehicles.
– **18**: This is the diameter of the wheel in inches. It’s essential to match this with your wheel size for proper fitment.
Why Tire Size Matters
Choosing the right tire size is not just about aesthetics; it directly impacts performance, handling, and safety. Here are a few reasons why you should pay attention to the tire size on your Audi S5 Sportback:
- Handling and Stability: The correct tire size ensures that the vehicle handles as intended. Wider tires can improve grip but might affect ride comfort.
- Fuel Efficiency: Tires that are too wide or have the wrong aspect ratio can increase rolling resistance, leading to lower fuel efficiency.
- Speedometer Accuracy: Changing tire sizes can affect your speedometer readings. Stick with the stock sizes to keep everything accurate.
- Safety: Proper tire size ensures that the tires fit securely on the rims, reducing the risk of blowouts or handling issues.
What to Consider When Replacing Tires
If you’re in the market for new tires, consider the following:
– Always refer to the owner’s manual or the tire placard found on the driver’s side door jamb for the recommended sizes.
– Consider your driving style. If you’re more performance-oriented, you might want to stick with the stock sizes for optimal handling.
– Think about the climate. If you live in an area with heavy rain or snow, you might want to look into all-season or winter tires that match the stock size for safety.
With the right tire size, your 2018 Audi S5 Sportback will perform at its best, giving you the driving experience you expect from such a finely engineered machine.
