Ok, well im buying some wheels for my 04 g35, and i need some rubber for them but im not sure of the width needed, heres the specs of the wheels im gonna order

AME Shallen CX
Front: 19x9 +18
Rear: 19x10 +22

I want a small stretch, i know i want them to be xxx/35/19, i just dont know the widths i need for them.. i was thinking 235s in the front and 255's in the rear

 

ttt? i think i'll get 245's in the front and 265's in the back

I would say either 245/35 up front or 255/35. Rears I'd go with 275/35.

Anything else and you change the stock wheel diameter too much and that can cause VDC, ABS, etc. to act up.

 

If you want a small stretch I'd suggest 245 up front and 275 in the rear
