They are off of a newer Civic, its 4x100, I know cuz my friend that has a 80 somthin rabbit wants them and he has 4x100. they are 16x7's, and what do you meen by offset? I was gonna take them to a place that does balance and instalation for cheap. I think that is a good idea dont you?
Also, What is the correct size tire that is suposed to be on them? Cuz the guy that knows the guy that is sellin them said he thinks they are p205 40 16, does that sound right?
