Trencher Tire Design

I am looking at buy an older Vermeer 4150A and I need to replace the tires. This unit also has a small backhoe attachment and weighs in around 4500-5000 lbs.

Is there a tire design and brand anyone might recommend that won't destroy the turf when I am just going on a property to dig small holes for tree rows?

I hate to grind the edges off a new set of tires (29x12.5x15 6 ply) and my chances of hitting the lottery are probably better than finding a used set in good condition in this size....
