Here's my thoughts ;
1) if you will NEVER use the tractor to cut lawn and will only minimally cross the lawn, then go R1.
2) if you will use the machine for loader work, light field work and will cross the lawn often - R4's. Also, if you road the machine r4's will last better.
3) If you will use the machine to cut the lawn, get the turf tires.
You can get tires "off the menu". The dealers will sell you the cheapest tires at the highest mark ups. They will almost always be low ply count. You can get high ply count Ag tires and many different tread patterns. You can also get radial or bias in R1 and R4.
