Is that a Woods belly mower? That's another pretty generalized statement. Ag tires work just fine on sandy soil. We live on a sand hill. The nearest clay is about three miles in any direction or about 80 feet straight down. I have three rib ag tires on the front and big ag tires on the rear of my 8N. I just need to take it easy on the turns and there is little, if any, evidence of tire marks. Those front tires can sure do a number on the turf if you do a sharp turn, though. I may put auto tires on the front. Can't really afford to go with turf tires all around.
