Rim rating

[lovenlif]

2004 F53 motorhome chassis which came with 245/70R19.5 tires, load range F.

Am going with a heavier tire and can't find any rating on the rims. Called ford truck services and got transferred to three different departments and people and no one could give me an answer. With the vin number you would think that they would be able to find that info. Finally was told only the engineers could help me. But they couldn't get me there and told me to call a dealership. Well, you're right, they neither had the rim rating nor knew how to get to engineering either.

Can anyone help me out with rim ratings for 2004 F53? I have all the tire inflation charts, know my GVWR, and axle weight ratings. Know more about that stuff than I ever wanted to know. Just need the rim PSI rating.

I may be mistaken but all aluminum rims( if that's what you have) have the weight rating stamped on them, usually in the back..
