Not sure on the install plan, Greg.
But here’s what I do know:
1) We have at least one gallon bag each of several styles of tires – see attached pics.
2) I have zero time to build until Thursday evening.
3) It should be fairly easy to stack tires somehow… could even be done on install day (many hands make light work n’at.)
So yeah. Stacks 2-3 tires high should be easy, could go on 1×1 round bricks (i.e. cannonballs) or flagpoles, or something.
