Hello, I'm about 20 miles north of Salt Lake City, UT. Unfortunately, there is little in the way of Steel Soldier's express out this way. Unless someone has a trip planned from the Salt Lake area to Phoenix, AZ area where Castel Bravo and 98G are. 98G seems to travel east often enough (at least Oklahoma), but I don't know anyone making that trip at this time.
I have a pallet at my disposal that I could ratchet strap the tires to and a friend who lets me ship/receive at his commercial business that can load via forklift. I could also take it to Fastenal. But then again, both of these options the seller of the tires could/should do too.
Just FYI: I had Rounder's Logistics estimate moving a ~200 lb pallet for me via LTL from North Carolina to Kaysville, UT (~2100 miles) and it was estimated at over $600. Fastenal was able to do it via their store-to-store shipping for $225.
