I cannot say enough good things about Diamond Back tires that I bought for my '50 3600 this year- they look the part and they drive like a modern radial. They are also super quiet. I have the black wall Auburn "Deluxe" radials (has a truck type tread on them).
710/15R in front and 820/15R in back. When I tossed the 215/75R15's that I had on the truck, it became considerably easier to park with the 710's on the front.
I had to throw away 4 tires with fewer than 300 miles on them due to flat spots. The front of these truck are HEAVY. If you're not driving them weekly, I highly recommend getting it up on jack stands. I have never tried the curved/contoured parking blocks that you can place under the tires- but some people swear by them.
