Note : Never downgrade the speed rating of your car tires. That is to say, never go for new tires with a lower than recommended rating, as it may result into steering difficulties and improper handling. The ISO Metric sizing system provides an alphanumeric code which is used to determine the rating of a car tire.

A tire with a H load and speed index is rated for a maximum load carrying capacity of 1, pounds. A tire with a T rating is capable of safely supporting 1, pounds. The load is per tire, so a vehicle with H tires has a maximum curb weight of 7, pounds, and one with T tires can carry 7, pounds.

The letter-indicated speed ratings are the maximum speed at which a tire can be safely driven. Then H, V, W and Y step up in that order at kph increments.

H Vs. V Rated Tires

Conversion to miles per hour means an L-rated tire has a maximum speed of 75 mph and a Y-rated tire can be run up to mph. The tire with the H index is "H" speed rated to a maximum of mph. The T tire has the lower "T" speed rating of mph. A vehicle with tires that have a load and speed index of H can be safely driven with a maximum weight of 7, pounds up to a speed of mph. The T tires will support a weight of 7, but should not be driven faster than mph. Both tires have relatively high load ratings.

For comparison, a Chevrolet Equinox that uses tires in this load range weighs about 4, pounds, leaving more than 3, pounds of load capacity. Vehicle manufacturers recommend against installing replacement tires with lower load and index ratings than the original equipment tires. Installing lower-rated tires can compromise the safe operation of the car. Also, the load and speed ratings are dependent on the tires being inflated to the correct pressure.

Under-inflation will significantly reduce the load and speed capability of a tire.

Although there is a lot of crossover, the H-rated tires will be available in more taller profile sizes and, as the tire profile gets lower, more tires will be available in V-rated or higher speed ratings.

Switching from H-rated tires to the higher speed V-rated ones may require the selection of a different size tire. There can also be a significant price difference between similar tires as the speed rating increases. The step from H-rated tires to V-rated is going from quality passenger car tires to performance tires focused on handling.

H-rated tires will have rubber compounds and tread designs optimized for all weather performance and long tread life. Performance tires, including many V-rated models, are optimized for dry road traction and handling.
