Where’s SPEED INDEX on tires? And how to understand it?

Every single tire in the world has the speed index on its sidewall. This is the standard demand for every tire manufacturer and all companies have to test their tires before they start manufacturing and selling them. So, the speed index means a certain maximum speed that this tire is safe to drive at. Once you drive faster than the tire is made for, you are in the unsafe zone and the tire may actually explode or get some damage. At the high speed, this may be a very serious problem for you and your car. So, I hope this less-than-one-minute-long video helps you check the speed index on your tires. And the next time you are on a speed-limit-free highway, you can consider the safe speed for your car!
