I know some are planning on installing new tires and wheels at the Rally.
I would suggest ordering the tires now and ship to your home location so you don't have to haul the off tires back with you. I have no way of hauling off used tires and wheels.
There may be some older RW there with ST235/80R16 E on them and the LT235/85R16 G coming off would make a great, inexpensive upgrade.
