Default x Pie?

I read a thread somewhere on here where you measure your tire height, rotate the tire 180 then measure again and... then divide or x by pie. Can anyone tell me how thats done? I am great with business math but the pie thing baffles me. Too long since high school I spose.. Time to put the flashpaq back to work and I understand from the afore mentioned thread I am measuring tire size incorrectly however it didn't specifically give measurement directions.

If I'm not mistaken, you take the circumference and divide by pi.

pi=3.14 the number goes on forever but thats all you need to know about pi, the easiest thing to do is park your jeep on flat ground and measure from where the center of the tire contacts the ground to the top of the tire.

What are your guys 35's measuring out to? Mine were just a hair over 33 inch tall wondering what yours are and if mine are small.

Yeah, I thought in the Flashpaq you entered the tire height (diameter) - no need to do serious math to work out the curcumference is there?

Thats what I did when they were new. Since then I read a thread on here somewhere about doing the math to find the true size. Probably doesn't matter. This thread was more about satisfying my curiousity..
