My problem when I looked for wheels and tires were (as I needed custom offsets) the 15" custom made wheels were as much or more than 17" wheel and the tire options for 15" were limited and lower performing and cost as much as better performing 17" tires. Below is how it turned out before and after. However, I do agree large wheels for the sake of doing it doesn't look right. Up to a 17" or some 18" can look clean and flow well with the car.
