One vertical behind each seat in the floor, the other two on the backseat, kinda slanted.

 

I don't know what Evo u have but I can get two tyres in the boot and two in the back 225/35/19 but with my tyres fitted to my rims I can only get one in the boot ( but with that said I have a large sub in the boot ) two in the back and one in the front seat. Oh yea I have an Evo v

I've fit a set of 255/35/18 in the back. 1 on the floor behind each seat and the other 2 tire tread to tire tread on the back seat
