What’s the difference between different-size tyres?
Tyres come in various sizes to accommodate the diverse range of vehicles on the market. Each tyre size is specified through a combination of numbers and letters that indicate its width, aspect ratio, and diameter, such as 235/45 R18. The width (235mm) represents the tyre's width from sidewall to sidewall, while the aspect ratio (45) indicates the height of the tyre's sidewall as a percentage of the width. The "R" signifies a radial construction, and the diameter (18 inches) refers to the wheel diameter the tyre fits.
Different sizes are necessary because each vehicle is designed with specific performance, handling, and comfort requirements. Smaller, narrower tyres are typically used on compact cars for fuel efficiency and easier handling, while larger, wider tyres are found on sports cars and SUVs to provide better grip, stability, and load capacity. Choosing the correct tyre size is crucial for maintaining optimal vehicle performance and safety.

Ensuring 235/45 R18 tyres suit your vehicle
When purchasing new tyres, it’s essential to ensure that you purchase the correct size tyres to fit onto your vehicle. Here are some tips to help:
Check your vehicle’s manual
Your owner’s manual will contain detailed information on the correct tyre size for your vehicle. Before purchasing 235/45 R18 tyres, we recommend you check your manual to ensure the tyres you’ve chosen are compatible and safe for your make and model. Verify the recommended tyre size in the manual before making your purchase to avoid disappointment.
Find your current tyre size on your tyre’s sidewall
Your current tyre’s sidewall will display information about the tyre, including the tyre size. Before buying any new tyres, be sure to check your tyres' sidewall. If you are unable to do so, you can also ask a trusted professional for the tyre size for your vehicle.
Speak with a Halfords expert
