What does 195 55R16 87H mean?
R stands for “Radial” and the last two figures 16 indicate the wheel diameter in inches. The size ends with the load index 87, which is the maximum weight that each wheel can support, and the speed rating H, which is the maximum speed at which the tyre is approved for use. For passenger vehicles, load index ranges from 75 – 105. H” represents the speed rating, which is how fast the tires can go based on their load capacity. This rating ranges from A – Z. H” indicates a speed rating of up to 130 mph.Letters ranging from A to Z represent the speed rating. Each letter denotes the maximum speed a tyre can sustain under its recommended load capacity. In our example, “H” is equivalent to a maximum speed of 130 mph (209 kph).The choice between H and T tires is actually based on speed ratings: while H-rated tires allow a top speed of 130 mph, delivering superior handling and heat resistance. T-rated tires max out at 118 mph and thus favor durability and comfort for everyday use.Take, for instance, the specification ‘195/55 R16 87V. While most people recognize the width, height, rim diameter, and load aspect, the alphabet ‘V’ at the end holds a specific meaning. In this case, ‘V’ denotes that the tyre can reach speeds of up to 240 km/hr.
