Understanding Tire Size Notation
The tire size notation can seem complex, but it breaks down into understandable components. Here’s what those numbers mean:
- 245: This is the width of the tire in millimeters. The wider the tire, the better the grip, but it can also affect fuel efficiency.
- 40: This number represents the aspect ratio, which is the height of the tire’s sidewall as a percentage of the width. A lower number usually means a sportier feel and improved handling.
- R: This indicates that the tire is of radial construction, which is the most common type of tire in modern vehicles.
- 18 or 19: This is the diameter of the wheel in inches. Larger wheels can enhance the look of the vehicle and improve handling but may lead to a harsher ride.
Choosing the Right Tires
When it comes to selecting tires for your 2015 Audi S4, consider the following factors:
- Driving Conditions: If you live in an area with harsh winters, look for all-season or winter tires that fit the specified sizes.
- Performance Needs: For those who prioritize performance, consider high-performance tires that can handle the S4’s sporty nature.
- Budget: Tire prices can vary widely. Make sure to balance quality with your budget. Cheap tires can save money upfront but may not offer the same safety and performance.
Maintaining Your Tires
Proper maintenance of your tires is crucial for safety and performance. Here are some tips:
- Regularly check tire pressure to ensure it is at the recommended level.
- Inspect tread depth. Replace tires when they become worn down.
- Rotate your tires every 5,000 to 7,500 miles to promote even wear.
- Keep an eye out for any signs of damage, such as cuts or bulges.
