Isn't the point of the metric system to be simple? what a bunch of hypocrites!

how could you get any easier than 33x12.50 ?

12" = 1', how many feet in a mile? i dont know im canadian, lol

my point:

10mm = 1cm
100cm = 1m
1000m = 1km

simple

tire sizes are complicated because they use metric, standard and percentages. eg. 285/75R16
285 = width in millimeters (mm), 75= 75% of 285mm = 213.75mm, multiply that by 2 because you have a sidwall on the top AND bottom... so 213.75x2=427.5, and finally 16 for the wheel diameter.

Final calculation:
285mm x 75% x 2 = 427.5mm + 16'

now THATS complicated

Oh and the R stands for Radial, and they will have a P or LT at the beginning for Passanger and Light Truck, and they also may have a speed rating beside the R eg. P285/35ZR18

ok now im done

3 feet in a yard, and 5280 feet in a mile.

to be honest, even Canadians use standard measurments for fabrication and daily use, the only people who use metric here are the people who are on the news and in politics. I was never taught anything but metric in school and i still couldnt estimate a meter, but i can do inches and feet, its weird

Yes, but in a perfect world, the 16" would have been converted to mm and factored into the equation (or number sentence as my boys were initially taught ).
