Dito bow man, those look like the right size for packing down grass seed. You will need about one more full yard of concrete before you will even start to fill the marks those tires are going to make. A full yard of concrete will cover up the wife you don't like also.
Hate to break up the pity party but I've already used it.
Works like a charm.
I use that tractor in the yard all year long to mow the grass and every thing else from grading to bridge building.
