would these fit with an eibach drop and would I need an hubcentric rings?
An offset of +31 would look similiar to my new wheels (
http://forums.altimas.org/zerothread/357279)-- you'll be sticking out a bit and it'll look hella aggressive. Also, if you take your car to the dealer you won't pass inspection with the wheels out of the wheel well like that. I wouldn't worry bout that, just take your car to a private shop.
But, I would get a smaller size tire than what you are looking at-- with this offset your wheels will look very similiar to mine-- just thicker tires. I have encountered a tad bit of rubbing, you may want to downsize your tire just a tad bit to be perfect.
I highly recommend hubcentric rings and by the way, those will be tight getting the tires on your wheels! Prepare to pay a few extra bucks a tire for mounting.
