Just purchased a pre-owned 2011 G37 convertible base model with most upgrades.Question: the car came with Nankang 255/40/R18 tires both front and back and not staggered width as per Infiniti standard spec. Does anyone see any issue with this tire size and setup. Tires are new so would prefer to keep them. They are a bit noisy but the tread recess width is quite wide which may contribute to this?

Thank you in advance

Slice you might get a better response in the G37 tire section....
