It's really a matter of preference and really depends on the conditions and terrain you're driving. Freeway, backroads, asphalt, concrete ect... A lower profile tire is gonna ride rougher than a thicker one obviously due to less sidewall cushion when it comes to tire performance. The car already handles well with either one and you can adjust the suspension to get the perfect stance for any side wheel and tire if you're going for just looks. I put 20"s on my 3000 even though there's alot of people that are against it, but it's your ride and do what feels right to you and not what anybody else says.
