Default Speedo Gear Question

Just ordered my lift and tires a little bit ago and i was curious which speedo gear i should go with to keep my speedometer/ odometer accurate. Thing is its a 33" tire but measures to 32.5".

So the question is would it be better to get the speedo gear for a 32" tire or 33" o.O

I would go with the one for 32" tires, mainly because the rolling diameter will be even less than the 32.5" you measured.
