I just got an 03' G35 sedan and i need to buy new shoes for my girl...

currently the rear is sitting on some 255/35/19 potenzas on a 10.5 rim...

I was wondering if anyone has ran a setup that was wider than 255 on a 10.5 rim without any rubbing?

I was planning on running at least 275/35/19s on her but i read that in order to do so, it had to be dropped atleast 1" and have an offset of 35...is that correct?

the previous owner told me that i can run 275/30/19 but i got a fat hookup for some kumho ecsta 275/35/19s...wondering if these would fit?

any help would be awesome. thanks bradas...
