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

The best research I have done says that there is no regulation that requires wheels to be identified by maximum weight carrying, or maximum pressure - BUT - wheels are designed and manufactured such that they will carry the largest weight for the vehicle they are fitted to - and that is controlled by the number of lugs.
Yes, that's right, the number of lugs. Then that controls the weight limitations of the vehicle and therefore the wheel.
Further, tire inflation pressure doesn't matter when it comes to wheel strength. It's the max load that overwhelms things to the point where stresses due to tire inflation pressure are trivial.
If the weight capacity of wheels was only controlled by the number of lugs all 8 lug wheels would have the same capacity which is not true . You have over simplified.
