What are Low Profile Tyres?

Low profile tyres are those with smaller side walls compared to other tyre types with the same width. Generally, low profile tyres have an aspect ratio of 45 or lower. Common examples include 225/40 R18, 245/35 R19 etc. Almost all modern cars with bigger alloy wheels, sports cars, and performance vehicles have low profile tyres fitted as standard.

Important information

If your vehicle was fitted with low profile tyres from the factory, you must replace them with the same specification. This means that you can not replace them with larger profile ones unless you also replace the wheel to one with smaller diameter to keep the rolling circumference correct. This is essential to ensure your speedometer works accurately and your ABS and traction control systems function as they should.

If you find the ride too firm, you can find out if your manufacturer approves a smaller wheel size with a higher profile tyre as an alternative. This information will show in our registration search results.
