To support running at higher speeds, V-rated tires will have a stiffer sidewall and slightly firmer ride than H-rated tires. For normal driving conditions the H-rated tire will provide a more comfortable ride and the V-rated should give slightly better handling.
Selecting properly rated tires is important for the safe driving and proper handling of your car. The tire rating system makes it easier to compare different tires and pick the right ones.
