I guess the rim size would be the diameter
Then you just add the width of the sidewalls
on both sides. Let = the width of the
sidewall. So, the total diameter of the tire is:
Take half of that to get the radius of the tire
--------------------
If the circumference of the tire is is ,
The width of the sidewall is 7.492 inches
-------------------
check:
looks OK

I'm not sure what aspect ratio is. If it is
width/height, then:
Let = the width
Multiply both sides by
the width is 33 and 1/4 inches
( not sure about this )
