My F250HD has single rear wheels and standard "non commercial" plates. The State Patrol around here are notorious for pulling over and ticketing anything that looks commercial. Having dual rear wheels makes you a target. Tickets/fines are almost automatic they have so many rules. I have talked to multiple people, owners of businesses around here who complained about getting pulled over and inspected with nothing on the vehicle showing a flaw and having their time and schedule messed up. They have gone to the state and were given stickers to put on their trucks that basically tell the patrol officers to leave them alone.
