Tire sizes are nominal. For accurate size info you'll need to see the specs from the tire manufacturer. Try tirerack.com, look up your tire, and click on "specs".

no i was wondering if you could do it. 70% of 215 is 150mm so then 150mm / 25.4 = 5.9 inches. so the dimiter of the tire will be 5.9x 2 + 15

just so you know how to apply it when you buy tires if you ever need to know
