I bought a used 2017 Maxima a little over a year ago. I love it - it's fast and as Julia Roberts said, "it corners like it's on rails". Problem is I don't know much about it - the User Manual is 417 pages! I'm counting on you good folks to keep me straight and informed.

I'm getting ready to have to buy tires and I'm so confused! Gonna start a thread.

 

Currently, on my pre-owned 2017 Maxima, are 245 35/20. It's time to replace 2-4 of them. But everything I've read says 19s and 18s are what it should be. Should I change? If I do go to 18 or 19, will I need new wheels too?
