While searching for best deal on Toyo M144 tires, I found that I could purchase online from Walmart with free shipping.
4 tires x $368.39 delivered by FedEx to my RV site in Keizer ,OR.
All tires had 2019 date code.
Found local tire dealer 2 blocks away to dismount/mount for $80 / wheel.
Saved $332.00 over Les Schwab quote.
