OK. I've taken my stock 17" wheels and added some Yokohama Ice Guards for the winter conditions I expect by November 15. My intent is to get new wheels and tires for next spring and swap them in April, and I have decided on Michelin Pilot SS for the rubber and am close on the wheels, but a question keeps popping up......Should I continue with the stock staggered wheel and tire widths, or replace all four with the same size on all wheels. I will go to a19" wheel and non-runflats, but question the staggered set up. I am not sure this isn't just for looks or the venerable N54 is simply too powerful for a skinnier rear tire..... Also, I am not sure if the extra inch of width in the rear adds noticeable traction/grip.....Thoughts?
