It appears you don't have many options for the proper sized 16" tires for an S4. I'm not interested in going with a different sized wheel (17, 18, etc). Some companies make the proper sized fronts but not the rears and vice versa. What do you do when replacing your S4 tires?

Square tires, ie the same size all the way around? If so, do you go with all fronts or all rears? I went all fronts with my '87 but not sure that's the proper way to go.

Do you go with a different size 16" for the front or rears that gives you better options for a full set?

A wider square set of wheels and tires would be ideal. but most go for a staggered setup.

Just try to get as much tire in the front as you can. An 8 inch wide tire doesn't sound much bigger than the 7 but it makes a HUGE difference.

I opted for a set of 18 inch Panamera wheels because they're cheap and high quality. 18s probably have the best tire selection as well...

Porsche has an excellent set of proper tires...

When I can[t find the 245 45 16s for the rear, (or even when I can) I go with 245 50 16. I like my rear tires on the 928 to be slightly larger than the fronts. In fact the 245 45 16 tire is actually slightly smaller in diameter than the fronts. The 245 50 16 tires are 25.65 inches tall and I find that idea. I think the 245 45 16 tires at 24.68 inches tall is just too short. In fact they are shorter than the fronts at 24.85 inches tall.
