My 2012 6.7 Super Duty diesel has 20" Cast Aluminum Wheels; the spare is 18". I finally decided to order a 20" wheel to match the other 4 and the listed weight on the back is 3250 pounds. I have scoured the backs of the OEM wheels but cannot find the weight limit. Does anyone know the weight limit?

The wheel weight limit is likely higher than the weight limit of any tire that gets mounted to it. I don't think it's a concern.

Hi kl, my original tires were 275/20's with a max weight limit of 3750. Those 2, rear, tires would carry about 7500 pounds, so from the factory, I assumed that the wheels would have to support the same load as the tire. I upgraded those to 295/20's with a max limit of about 4100 pounds just for a larger tire. The scale weight of my truck with 5th wheel is a little over 7000 pounds; dry wt is about 3700. So the tires and wheels are well within safety limits. But, with this new wheel, with a weight limit of 3250, seems unsafe. That's why I'm curious. If the OEM's have the same rating, I guess that I have nothing to worry about.
