Mille Miglia Type 15 / ATP Type 8

I have a 1984 280SEL (4spd auto) with the original 14" bundt-cake rims. I have settled on the two rims (as far as looks go) above but since the ATP Type 8 comes in a 16", I'd like your opinion on which to buy and a recommendation for an approriate size/manufacture of tire. I like the idea of having a larger/wider more agressive stance for tires. I've heard that the 16" wheel will handle better and ride nicer? What are the pros and cons? TIA to anyone who will pass along their experience(s). Hal
