My son is getting tires for his recently purchased 1996 Ford F250 2WD he's going to use for landscaping work. The tires he got quotes for are the Nokian Rotiiva AT and the Yokohama Geolander A/T-S. The Yokos are a bit cheaper. Which do you suggest? Since his truck is 2WD he knows he will be getting stuck in yards when he has to drop dirt and gravel so mud capability is a factor as well as not tearing up turf.
