245/60/15 BFg radial TA load rate issue

[Lost81c10]

Ran into a load rating issue...I decided to finally replace my tires and wanted to run 245/60 for the front and 295/50 for the rear on the 10 inch rallies as many have done. So today i decided to go to Discount tires to order a set of Bfs and to my surprise, they tell me they cant get me nor install the tires due to the tire load rating on them. They say that the fvgw is more then the rate on the 245s. What am I missing here? How have you all dealt with this kind of issue or worked around it. I see them on a lot here…puzzeled….
Thanks.
