When it comes to the 2018 Audi A5, choosing the right tire size is crucial for optimal performance, handling, and safety. The A5 is a sleek coupe that combines style with functionality, and the right tires can make all the difference in how it drives. Let’s break down the stock tire sizes and what they mean for you as an owner.
Stock Tire Sizes
The 2018 Audi A5 comes with a few different tire sizes depending on the specific model and trim. Here’s a quick overview of the stock tire sizes:
| Model | Tire Size | Wheel Diameter | Aspect Ratio |
|---|---|---|---|
| A5 Coupe | 245/40 R18 | 18 inches | 40% |
| A5 Coupe (Sport Package) | 255/35 R19 | 19 inches | 35% |

Understanding Tire Size Notation
The tire size notation may look like a jumble of numbers and letters, but it tells you everything you need to know about your tires. For example, in the size 245/40 R18:
– 245: This is the tire’s width in millimeters. A wider tire generally provides better grip but may affect fuel efficiency.
– 40: This is the aspect ratio, which is the height of the tire’s sidewall as a percentage of the width. A lower number means a shorter sidewall, which can improve handling but may result in a harsher ride.
– R: This indicates that the tire is of radial construction, which is the standard for most modern tires.
– 18: This is the diameter of the wheel in inches that the tire is designed to fit.
Why Tire Size Matters
Using the correct tire size is essential for several reasons:
1. Handling: The right size ensures that your A5 handles as intended. Incorrect sizes can lead to poor steering response and stability.
2. Safety: Tires that are too small or too large can affect braking distances and traction, especially in wet conditions.
3. Fuel Efficiency: Incorrect tire sizes can negatively impact your vehicle’s fuel economy. Wider tires may create more rolling resistance, leading to increased fuel consumption.
4. Aesthetics: Let’s face it, the look of your car matters. The right tire size enhances the overall appearance of your A5.
When to Replace Tires
Tires don’t last forever. Check for the following signs that it might be time to replace them:
– Tread Wear: Use the penny test. Insert a penny into the tread; if you can see Lincoln’s head, it’s time for new tires.
– Cracks or Bulges: Inspect the sidewalls for any visible damage.
– Vibration or Noise: If you notice unusual vibrations or sounds while driving, it might indicate a tire issue.
Keeping your 2018 Audi A5’s tires in top condition is vital for performance and safety. Always refer to your owner’s manual or consult with a professional if you’re unsure about tire sizes or replacements.
