The speed rating of a set of tyres is the maximum limit of speed. It means, your tyres are not in the safe zone if you go beyond the limit. Generally, English letters represent the speed rating of a vehicle. You can find the information about the speed rating on the sidewall of the tyre.
Tyres allow your car to move seamlessly from one place to another. Without the presence of tyres, the movement of the vehicle from one place to another is impossible. This is why tyres occupy an integral space in the movement of the vehicle.
Low-profile tyres have extremely flexible sidewalls, which make them ideal for curving roads. These tyres are nonetheless vulnerable to road damage due to their stiffness and small width. This is not a problem if you live somewhere where the roads are properly managed.
Reduced traction results from overinflated tyres having less contact with the road. It is therefore more difficult to stop swiftly and securely, particularly on slippery or rainy conditions.
