Looks like a great project.
it also looks like you have 4 weeks of work left till you will be testing the grip of the tires.
i would call the vendor and see if there is anything the manufacturer can do to bump you up a bit in the waiting list.
People make mistakes, i know i do!!! S%*t happens, honestly most manufacturers will do everything in their control to keep you happy.
sometimes there is nothing that can be done to speed up the order, in these tough times it is difficult to have everything in stock all the time. and that goes for the manufacturers suppliers as well, so it reall trickels down.
Call the guy you purchased them from!!! comming on here isn't going to help.
