The OEM tires are excellent, which for 2020, on the rear drive only are Michelin 4S (these are summer tires, dont be confused by the 4S). I have a new AWD V6 which has all season, and they are better than expected. The Maxima I traded in had the Michelins and I loved them.
The Michelin PS4's are great! I couldn't believe they were OEM on the car! I had a modded VW GTI before and the Michelin PS's were the only tires I found that could handle the torque on an overpowered FWD go-cart... I replaced the PS2's I wore out on my GTI with PS4's and they were a good deal quieter while still having insane grip when properly warmed up. I think I would definitely go for rims before changing the stock tires on my G70.
