tire and wheel change over questions

[k7cdl]

its not so much i plan on doing heavy hauling but better to go over kill on load rating then go under rating. i'm sure that 454 puts a lot of weight on tires alone. plus in 2015 i'm going to look at doing a 5k mile trip and it would be nice to have a good set of 10 ply tires when hauling an ATV and a travel trailer for that long mile. I guess I just drove truck for 2 1/2 years no longer drive semi but learned in that 2 1/2 years better to go over kill on tires and not need the over kill then to need the better tires and be stuck in the middle of no where
