Like for like is best.
If you fit it straight from the factory then expect to get 10 years + from it.
If you give it a coat of rust protection then it will outlive the car.
Plenty in stock if required, treated or untreated.
You wont go far wrong with Yokohama A052.
I run 235/40 18 and 265/40 18 on OEM Rays.
If you want to go the Federal 595 RS-R route then I have a spare new set in stock, same sizes as above.
I have a full kit in stock including the intercooler and associated pipework.
Do you also require engine tuning/management stuff and gauges or are you going up rev?
Do you also require an uprated fuel pump and fuel return system and injectors?
Everything in stock and good to go same/next day.
Just let me know what you require here or by PM
Not advised IMHO.
Did you mean 595/596?
You really require a 245 or more on the rear.
You will have circa -2.5% difference in rolling radius.

If the car is new to you and you are unsure of the past service history then I would advise getting a 60,000 mile service completed by a recommended 350Z Indy specialist.
The drive belt should be replaced if showing signs of wear or is past the self adjusting maximum mark.
The spark plugs should be replaced if the gap exceeds 0.055in.
The diff fluid change is straight forward and should be changed depending on the past driving conditions.
Have a look at the Nissan service intervals etc below.
