No, in fact you can CALCULATE the size of the tire from the metric tire
size on the side of it... I have a spreadsheet that does it, but there
are also websites that do it.

Try searching for "tire size calculator" or look at powerdog.com I
think.

My spreadsheet is at:

http://wps.com/AMC/axle-ratio-tire-MPH.xls

(It does tire size, axle ratio, engine rpm, mph in each gear, engine
cfm, etc)
