that would be my driveway. as much as I would like it paved its a little cost prohibitive,. I dont take it outside that often but it would be nice if I could without fear of getting stuck. its not essential to take it outdoors. but would be nice on the rare occasion I need to unload a truck on the street. I thought it would be more cost effective to convert to pneumatic vs paving my driveway.

now can someone tell me why it cannot be converted to pneumatic? other that the mfg says no. which Im not one to adhere to what a mfg tells me without good reason behind it.
