Hello - Please note that I was on www.tires.com and I noticed lots of choices of rims for good prices. (note this is a extra set for winter but still want them to look nice) Regardless I see that many are sized at 17x7 and others are 17x8 which is better? My winters tires are the same size as the stock tires....

I really don't know the difference so if someone could help that would be great...

Thanks
