I have rim guard in mine - environmentally friendly, heavy, no rusting rims. Downside? More expensive.
When my tractor was first delivered, the tires weren't filled, the dealer filled them at a later date. I noticed that when mowing on hills, I used 4wheel drive less as the rears had much improved traction. Also improved stability when using the loader. An attachment on the three point is recommended in addition to the filled tires for heavy loads.
