Are metric and standard wheels interchangeable?

Their sizes are essentially the same; they correlate to the same width, height and rim size. The main difference is with the load carrying capability. Euro-metric tires do not have a standard or uniform way of calculating the tire’s load bearing capability.

How much difference in tire diameter is acceptable?

Generally, it is recommended to not exceed a 3% difference when changing from the OEM size on a non-modified vehicle. A green row means that the alternate tire diameter matches the calculated tire diameter.

How do you convert metric tires to standard?

The first number on a metric tire is the width in millimeters. Divide this number by 25.4 to get the inch equivalent as there is 25.4 mm in 1 inch. The third number generally preceded by an “R” is the wheel diameter. The sidewall or aspect ratio are used in metric tire sizes to determine the overall height of a tire.

Why are metric tires more expensive?

They are more expensive than p-metric tires. This is because LT tires have extra material in the sidewall and under the tread that protects the tire from damage. The cords in a LT tire are a larger gauge than P-metric tires so the tire can carry heavier loads.

Does tire size have to be exact?

Width and diameter are the two factors that determine tire and rim compatibility. For diameter you’ll need to be sure that your tires and wheels are an exact match, e.g. a 215/65R17 tire will only fit on a 17″ diameter wheel.

Why are some tires metric?
