According to Wikipedia, the NB Miata is 1680 mm wide. I run 225 tires, so that’s 450 mm of rubber. 450 divided by 1680 yields... 26.7%. More than a quarter of the car’s width is rubber meeting the road.

My 323 GTX runs 185 snow tires, and its listed width is 1645 mm. 370/1645 = 22.4%

Who’s got the most rubber in relation to car width? The least?
