Understanding Tire Speed Ratings And Load Indexes
The tire speed and load index ratings will tell you how fast a particular car model can go, but they’re not the only factor involved in determining what kind of driver is an excellent candidate for that specific type.
How Is Tire Speed Rating Established?
A tire’s speed rating is established under controlled testing where it can be verified as capable of safely running at up to the indicated miles per hour. Heavily worn, damaged, or punctured tires would all be considered suboptimal and no longer meet this standard for performance in a car due to being too dangerous.
Frequently Asked Questions

Why do you need the same tires on all four wheels?

There is no practical reason to mix different tires except to replace individual problem tires so you likely would have different tread depths in addition to tread patterns, which is not good.
Why are tires wide?
On the dry roads, wide tires will give you extra grip in corners, you will have more confidence. In principle or theory, you could make your tires too wide, so that they loose grip in the dry as well , or do not warm up proper, but you will struggle to fit tires that wide on your car.
