Decoding the letters and numbers on your sidewall seems far more complex than it actually is.

215/40/R17 tyres are predominantly used on mid-sized vehicles such as the Skoda Fabia or Rapid as well as the Suzuki Swift Sport, Volkswagen Polo and the Audi A1 and S1. In order to decode the size, we need to first establish what each part of the code means. The first number, 215 refers to the width of the tyre in mm.
The 40 refers to the profile of the tyre. What this means is that the height of the side wall is 40% of the width. R means that the tyre has radial construction. This is the most common form of tyre construction used today. The cord plies in a radial tyre are arranged at 90 degrees to the direction of travel. The 17 refers to the width of the rims or wheels. In this case, the wheels must be 17 inches in diameter.
215/40/R17 tyre pressure will vary based on a range of factors, including the weight of the vehicle. It is generally expected that these tyres will have a pressure of between 34-36 pounds per square inch. That said, you should always check the manufacturers' guidance for your vehicle in order to find out the optimal tyre pressure for your vehicle.
