I'm getting 18x8 Rims and I need tires for them aswell, so will 235/50ZR18 fit them? I'm new to this website so if I did something wrong let me know please.

 

That tire fits on that wheel, but you don't want a 235/50/18 on a 350Z. If you are stuck with four 18x8 wheels, I suggest a 225/45/18 front and 245/45/18 rear. Alternatively, you could get a 245/40/18 front with the 245/45/18 or 255/40/18 rear.

 

245/40-18 would be the preferred size if you're going 18 x 8 all the way around, at least that way you could rotate them. The difference between 245 and 255 in section width is so minimal that it really wouldn't be a benefit to stagger them IMO.

 

Agree. I have owned 18x8 wheels. Stay with OEM tire sizes:

F-225/45WR18
R-245/45WR18

 

if the rear is 255/40/ZR18 and the front is 245/40/ZR18 do i need to get 2 different size rims instead of 18x8 or 18x9 or something??

 

No, those sizes would both work fine on an 8" wheel. But if wider wheels are an option, you are better off going that route. At least 8.5" in the front and 9.5"+ in the rear. May I ask what wheels you are looking at and what offsets are offered?

 

isnt this manufacture wheel setting? ahhah 225/45/18 front and 245/45/18 rear?

 

+ good choice.

 

Not sure I kinda want something with a lil black and like a chrome lip, do you have any suggestions? that are low priced? :/ i'm tight on money ha

 

bad idea^^

 

nah manufacture is P235/50WR17 on all i believe

 

K i found what i want but when i get ready to order it it says something about the TPMS on my car isnt new enough for the "QUICKSET" (whatever that is) saying they have to be initialized at the dealer. any help?

 

Do not understand. Assume that you HAVE 18x8 wheels. Now you are looking for wheels to fit tires? Think you have it backwards.
