Right now I have Z rated 16 inch Potenza tires on my car that I have had since I bought the thing, and I was looking into getting some low profile tires. I like the low profile tires because of the look, but are there any serious side effects from getting low profile tires? Also, do they sell low profile 16's, or will I have to get bigger rims? Mine right now are somewhat low profile, but I was looking for a much slimmer look, so any suggestions of good low profile brands would be appreciated, and pictures would be nice if anyone has any. Thanks.
