How To Choose Your tyres
Choosing the correct tyre size for your vehicle is crucial for safety, performance, and fuel efficiency. Here’s a step-by-step guide to help you select the right tyres:
1. Check Your Vehicle’s Manual or Tyre Placard
Every vehicle comes with manufacturer-recommended tyre sizes, which you can find in:
The owner’s manual
The driver’s side door jamb on a sticker
Inside the fuel flap or glove box
This information includes the tyre width, aspect ratio, and wheel diameter.
2. Understand Tyre Size Notation
A typical tyre size looks like this: 205/55R16 91V. Here’s what it means:
205 – Tyre width in millimetres
55 – Aspect ratio (height as a percentage of width)
R16 – Radial construction with a 16-inch wheel diameter
91V – Load and speed rating
3. Consider Your Driving Needs
City Highway Driving: Choose tyres with good fuel efficiency and tread life.
Off-Road All-Terrain: Opt for tyres with deeper treads and reinforced sidewalls.
Performance Driving: Low-profile tyres with higher speed ratings provide better handling.
4. Maintain the Correct Tyre Load Speed Rating
The load index indicates the weight the tyre can carry, while the speed rating determines the maximum safe speed. Always choose tyres that match or exceed the manufacturer’s recommendations.
5. Ensure Proper Fit for Your Wheels
If changing wheel size (e.g., from 16-inch to 17-inch wheels), ensure the overall tyre diameter remains within 3% of the original size to maintain speedometer accuracy and proper handling.
6. Check Local Regulations
Some regions have laws regarding tyre modifications. Verify that your chosen tyres comply with local safety regulations.
