MPG For Speed .com. Unfortunately, it's true. Your car's gas mileage decreases once it gets past its optimal speed. For most cars, this is around 55-60 mph. This means that every time you go over this speed, you're essentially wasting gas and money - and creating unnecessary greenhouse gases.
Once you know your tyre speed rating, you can work out what is the maximum speed your tyre is capable of maintaining. For example, the W rating seen in the image, tells us that this tyre can reach speeds of up to 168mph. Speed ratings are based on tests in which engineers run the tyre at 6.2 mph steps, in 10 minute increments, until the required speed has been met.
