how can i tell how much lift?
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

Five thouand two hundred and eighty.
All the mm and km confuse the crap outa me. Im with madmax, just give me the dang number in inches so I can understand it.
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




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
).
