best tire size for 350z 17's on s13

[jpm1105]

i just got the 350z 17's wheels with the stock tire specs...225/50/17 i think, whats the best tire size option for s13 without stretching...maybe 225/40/17? or 45?

I always though 350 rims were 18s?

No one year of base model z's were 17's. Just use stock size for them. That should work I believe.

The tires in the picture might have 40 series tire on them.

I have 45 series tires on mine.

Ugh... I disagree.

Those wheels are 17x7.5+30 and 17x8+33. An S13's apect ratio is gonna be all kinds of fucked up if you use the stock tires that a 350z would use, which are 225/50/17 and 235/50/17.

I'd say use a 205/40/17 for the fronts and 215/40/17 rears.

If you're worried about if these sizes are stretched, heres a 215/17/40 on a 17x8 on the front on this NSX:
