I think oem size is 245 in rear, 225 in front

 

on my 17 i am running
255 55 17 front
225 55 17 rear

 

245/40/19 225/40/19

No issues here, 350z oem suspension

 

You must have rolled fenders though right?

 

And wait why do you have 255's on your oem 17s in the FRONT? That's way too big for OEM's for the rear, even more so for the front..You have a sedan?

 

Nope, I thought this was a popular setup?

 

idk i bought it like that

 

oh ight i plan on getting h&r springs will i need a camber kit n will i rub still

 

I don't know about that setup, I was just going for performance so I wasn't looking to be low

I didn't need a camber kit, I was barely able to get the alignment in spec

 

Hmm that's interesting, our overall diameters are nearly identical. I plan to drop on full revised Z suspension, but I needed to roll fenders.

255 in the front is way too big. But anyway how much meat are left on the tires of the rays? If you have money to purchase new tires, I'd do so.

 

No idea , mine is from a nismo but they are the same height

the front have about 10-20% thread left and the rears are nearly bald...... i dont have the money now so i am looking to buy used tiresss

 

DVG you run 08 z suspension? isnt that h&r springs

 

Tires only get worse and worse so I don't know why you would want to start with degraded tires

 

I'd go with 235/40/19 front (identical overall diameter size to OEM), and 245/40/19 rear (speedometer/odometer will be 1.5% slower than OEM, but at least you'll have a nice straight sidewall on the rear. But for example at 60 mph, it's 1.5% slower so you'll actually be going 60.9 mph. Not a big deal)
