Questions
What size tires does a 2023 Nissan Maxima have?
The 2023 Nissan Maxima came with 245/45R18 or 245/40R19 tires, depending on the trim and wheel size.
Which size is on my 2023 Nissan Maxima?
Look at the sidewall of one of your tires: the size is the code that looks like 245/45R18. The label on the driver's door jamb also lists the original size and pressure for your exact trim.
Can I fit a different tire size on my 2023 Nissan Maxima?
Stick to a factory size for your wheel unless a tire shop confirms the swap. A different overall diameter changes speedometer readings and can upset ABS and stability control, and the load index must be at least the original.
