Is there an actual advantage to BBP vs SBP?

yeah, because all the wheels in BBP come in 17-20"

Apparently all the tires that come on 17-20" are low pros too?

Try to learn math and product availability. In addition realize that not everyone has the same taste or closed mind you seem to have.

These looks like bandaids to you? They are 18's.

Now while this may not be your flavor, it's a pretty damn nice ride.

Ha! Yes math!! That Chevelle looks to have what18=20 inch rims and75 series tires?? It is a fact we all do not share the same taste! and that's fine with me. Bandaid tires, Just not my taste. Product availability ie choice of tire size and companies. You are right. 15 inch tire selection is terrible. I can hardly find anything rated to run over 150 MPH.....
For instance my '95 Dodge Ram 3500 Cummins, I bought it new. Came with itty biddy 16 inch rims!!!!! Wow it looks stupid!!!!! IN todays world of bigger wheels/tires, and $60,000 1 tons. ??? Good thing I am old and can do math. I know I can never afford a new one at $70,000 , but hey, it has those BIGGER wheel!!!! ha.... Hardly an choice of 16 inch tires. Have to wonder how I can still pull that 32 Ft gooseneck stock trailer!??????????
