Go measure the height of the dolly where the tire sits, then measure at the front tire of the vehicle dead center on the tire to the wheel well, then raise the car by the amount of the dolly so that the wheel well has the same height above the dolly's wheel height, remember that you will no be using the tire measure at all since the suspension will unload.
To recap ground to wheel well measure add dolly height from ground to where the tire will rest, raise vehicle and then check clearance from rear tire to bumper that will be what is called the escape clearance angle, just remember that any uneven pavement of gradient will infringe upon this angle as in gas stations and parking lot entrances, for me I would use a trailer rather than a dolly.
