No worry.Here are some years that will work, based on my research which has uncovered ACTUAL vehicles, these years (as below) with the SAME size tire. Many, are owners, who post info about their car on various automotive based websites... Enthusiast sites and such.
I have access to a lot of good info, as I'm networked thoroughly in my business. I have been diagnosing/repairing cars & trucks since the 80's. I have been online, non-stop, since 1997.
With that said, let us get back to your Question >>
Either size tire, when used with appropriate wheel, will fit:
1) Maxima Cars from; 2004 to present.
2) BMW 3 Series from; 1999 to present
3) Porsche 911/Carerra from; 2004 to present
PLUS - all cars noted in my original Answer. This does NOT mean these tires cannot fit other/older model years, or even different or modified cars of ANY year, make or model, for that matter. All this means is, the cars/years I have researched and listed, are from owners that have used the tire sizes in your question and listed there vehicles online. Lastly, I have uncovered additional and HELPFUL info for you... Read On >>
