15+ years in tire development and vehicle dynamics testing
Understanding tire sizing is crucial for vehicle safety, performance, and efficiency. Our engineering team has developed this comprehensive guide to help you make informed decisions about your tires.
Understanding Tire Width
Tire width is measured in millimeters from sidewall to sidewall. Wider tires provide better traction but may reduce fuel efficiency. Our calculator helps you find the optimal width for your driving needs.
Aspect Ratio Explained
The aspect ratio is the height of the tire’s cross-section to its width. Lower aspect ratios (performance tires) offer better handling, while higher ratios (comfort tires) provide a smoother ride.
Tire Construction Types
Modern tires use radial construction with layers of fabric and steel belts. Understanding the construction helps you choose tires that match your driving conditions and vehicle requirements.
