I'm trying to price a set of wheels for my new elantra. It has 16x6.5in steel wheels now and the premium model runs on 17x7in alloys with p215/45 R17 tires. Thats the size I would go with but I need to know the wheel offset, before I can really find the right wheels. Ive look at several specification lists and cant seem to locate this information. I would really appreciate some help.

 

also what is the correct bolt pattern 5X?
