Will these tires be ok on my F450?

[switchmaster]

Hello all,

I drive a 08 F450 and just purchased 6-245/70/19.5 Goodyear 12 ply re-groove-able g670 rv tires for it. I did not noticed the (RV) until I got them home and looked at the tires. Do you think it will matter if these are RV tires on my truck for they are the same tread and tire size as the ones on there and they are 14 ply? Thank you for everyone's time reading this and their reply. I cant return them for I did get them used, but the tread is 90% on them.

if your asking if they are safe to use absolutely, probably wont be good in snow but for highway use just make sure you dont go over the max rating.
