I ordered a set of P-Zero's... 2 @ 225, 2 @ 245. The 225's are here and installed, but the 245's are on back order, and have been for a month. I hear it could be up to 2 more months before they get in. What other tires would make a good match-up for P-zeros if I canceled the order on the 245's and went with another brand?

Why do you want 245/45-16s in back? Your car will understeer, unless you stiffen the rear or soften the front (if your sway bars are adjustable).

I have a set of four 225/50YR16 P-Zero Asimmetrics on my FD now. They handle beautifully on track and are actually faster than my old Yokohama A032Rs (same stock size). Of course my Hoosier R3S03s in 245/45-16 on 8.5 x 16 wheels are 3 seconds faster, but the Pirellis are pretty damned good considering they are street tires!

My suggestion is to get 2 more 225/50-16s to put in back. The 245/45-16s will be too wide for the 8-inch wide stock wheel anyhow. Even if you squeeze them on the rim, you will not be making the best use of the extra 20 mm of section width.

It's best to use either 8.5-inch or 9-inch wide wheel for a 245 mm section width tire. I don't know any manufacturers (except for the Kosei K1 Racing wheels that I have) that make 16-inch diameter wheels with anything wider than 8 inches. The '86 to '89 Porsche 930 Turbo rear wheels come in 9 x 16s. Unfortunately the offset doesn't work for our FDs

I guess if you really want 245/45-16s back there, you could go with the Continental ContiSports. The tread patternis similar to the P-Zero Asimmetric, but the rubber compound on the ContiSports is harder and less sticky than the Pirelli compound for the P-Zero (from what I've read--I have no actual experience with the ContiSports!).

IMHO, it's better to stay with the same tire brand all around.

Dont mix tire brands... the break-away characteristics will be different, the wet/dry traction will be different... you'll end up with a car that handles somewhere between goofy and dangerous. MHO.
