I have a mobile tire machine that we took to events back in the day… Charged 5 bucks a tire for dismount and remount… I have it up for sale because we all run 18’s and the machine cant do anylarger than 16’s so its no use to us anymore, If i dont sell it by the time of the first event, if someone has a truck and wants to hookup to my trailer to bring it down and use the tire machine… im cool with that… Youll need a 5th wheel though, its not a regular ball hitch
