How to read your tires
How to read your tires, what is the dimension that has your car
Suppose we have the 195/65 R 15 91H:
195: is the width of the tread and more specifically the distance in millimeters from one sidewall of the tire to the other.
65: is a number denoting the ratio of height to width of the tire and the smaller, the lower the profile.
R: symbolizes the way of construction of the tire and more specifically that is radially made (Radial).
15: shows us what wheel must be placed said elastic and is a numeral indicated in inches.
91: indication referring to the load index and could be explained as the weight you can lift each tire under suitable pressure and temperature conditions. The following Table A is the assignment of numbers to be read in the walls of the tire in relation to the weight that can withstand. In our case, 91 means that each tire can withstand up to 615 pounds.

• Η: ratio of the maximum speed that our tires can travel safely. So the dimensions given these tires under Table B below, withstand up to 210 km / h.
