6.5" works out to 165mm - which is horrendously narrow for an inflated tire, at least by today's standards. So that 6.5" is probably the rim width.
For tire sidewall height, I would inflate the tire to, maybe, 3-4psi below the max pressure listed on the tire, remember, it doesn't even have to be on a car, just on a rim.
Next, measure from the rim up to the highest point on the tread. That's your sidewall height.
