tire rim weight rating
Hi , Just wondering how do you go about determining the weight rating of rims? I have 18" steel rims Thanks Lou

Not all rims have weight rating on them as was done some years ago. It can be tricky to ascertain this data. My factory rims had no such numbers, inside or out.
When I was going through all the arithmetic on my last set-up, the one thing on which I was fairly certain: The wheels at a minimum were able to handle at least the weight of the stock tires from the factory that were wrapped around the wheels. Sounds simplistic, but I imagine the lawyers for the truck manufacturers would not allow for a higher tire rating to be installed on a wheel that would not be able to at least handle that.
This does not mean that in the real world that the wheels are not capable of more loading, its just that the truck maker will not stipulate it.
FWIW- when I calc'd my set-up, I was over the wheels (per the above assumptions) by 75# per wheel but well under axle and tire ratings since I upgraded the tires.
I was comfortable with that weight on any known wheel rating since these were steel wheels.
