got some rims off of a b6

[Erock]

today i picked up a set of moven sp10's they were on a b6 with 235/40/r18 but they need to new tires will 235's work on the b5 or do i need to get some 225's? I believe the offset is 35. Also do i need to get longer lug nuts or will the stock ones work good enough?

I'm running 235/40/18' on 18x8 wheels without issues. I'm not sure about the bolts though.
