Yes, I did put the tires on the wheels. What I'm having trouble with is that the technic connectors allow the small wheels to move to much and hit other small wheels or the plates with six holes. I noticed on the Ldd file that there's 6 in gray, 4 in black, and one in blue and white, does that have anything to to with it? Mine are all black.
EDIT: Pictures.I circled problem areas.
