I was looking at the body builder guides 2009 verse 2010. what stands out the most to me is that in 2009 the trailer weight max difference was 1,000 pounds between the 17 and 20 inch rims, now it is 50 pounds. 2009 you lost 1000 pounds and in 2010 50 pounds, how could that be? wow.

 

This has been discussed - they increased the rating, without really making any changes. Sounds like they were trying to be extra cautious when the 4G came out.

 

I understand that the weird thing is they put a huge change into the tires/wheels, that is a 950 pound difference, are they the same tires?
