Hey guys could you clue me in a little bit on this? I've found confusing (i.e. conflicting) information on the proper wheel offset.

I'm looking to possibly get some 18 x 8's. I know the stock rims on my '05 are 53mm offset. The ones I'm looking to get say they are made for the '05 but the offset is 49. Is this going to be a problem?

How much does a slight difference in tire height make? Is there an "acceptable" amount you can raise or lower tire height? Found this cool wheel size calculator o/l: http://gs.tolan-hoechst.com/tirecalc.htm

Don't worry about offending me by making things too simple. This is the first time I've really dealt with changing rime size and offset on a car so I don't know much.

Thanks.
B
