Shopping online for two rear Bridgestone Potenza S001 runflats for my 2013 335 (xdrive).

I notice prices differ greatly between a 255/35/19 92Y and a tire of the same size, but with 96Y load. I currently have the 92Y, but the 96Y's are significantly cheaper.

Any reason why I can't put 96Y on the car instead? (assume this just means I can carry more weight, but is there a physical element that I should consider?)
