I didn't realize the Scopebuggy wheels were that large. Perhaps I was thinking of the JMI version.
Yes, I will need some type of pneumatic tires to get across rough gravel, stones, and driveway edging, etc.

Curious .... how is it it, vibrationwise, viewing through a scope when it's resting on those pneumatic tires? Do you have to take the tripod off the buggy?
