You would have to know the tire size to establish the outside circumference of the tire.

Seriously, I would save my calculator and have someone drive a car along side. Your torque converter and how the power train is set up will affect the throughput gearing.

Hope this helps,

A bicycle speedometer is a good cheap way to add a speedo to a go cart. You can find them for $25 or less. You just attach a magnet to an axel or wheel where the sensor can see it go by and you program in your wheel circumference.
