Mario Kart 7 has a file called KartConstructInfo.bin, which has data for the tire placements. I managed to edit that file and combine 2 tires for the back and 2 small ones for the front, I also altered the kart's height because this mod goes over the standard kart.
Because this file changes the tires and kart height, it also changes their hitbox, which is cheating when using it online. So it won't be released as a mod.
