I have an '05 XLT Sport Trac. Though it is na XLT it came with the smaller 235/70/16 tires from the factory. I have recently replaced them with 255/70/16's. Dramatically imrpoved the truck ride and handling!! I bought the General Grabber HTS based on excellent reviews on many web sites inclduing Tirerack. My question is, what impact on the truck will going to the taller tire have, if any? My speedo may be slightly off, but will there be any other impacts? Shop manager where I had the tires installed siad he did not think there would be any impact since this tire size was an optional size and the percentage in height change was within the range to usually not impact the speedo, but I keep reading about gear ratio differences based on tire size from the factory. Any suggestions appreciated.
