State vehicle inspection, tire specific

Hi All, does anyone know if tire type and size are looked at in a state inspection? I know they look at condition and tread wear but here my situation. Just bought a 2500 truck that was Maryland State inspected by the dealer. It has P265/70/17s. Ordered new ones from Costco, went today to get them installed and the guy said I had the wrong tires. We went out to the truck and sure enough, on the door tag it calls for LT265's. Truck is only a year old so someone must have jacked the LT's and put on the P's? So the question is..............
If the door tag says it has LT's and it doesn't, does that pass a state inspection?
Thanks in advance, Bob
