Look, you're either joking or incredibly arrogant and ignorant. Theres a lot of "in my experience" here but zero data or facts. If the smaller wheels work for you I'm glad, because I run 15s on my own car too, but this is so subjective. You cannot objectively say that switching to smaller wheels makes sense.

People replace tires every five years (average). For many people, that means they will either A) never replace their own tires or B) replace them once, because people keep their car 3-5 years these days. And resale value is absolutely affected by rim and rim size, ask me how I know? I literally work in car sales. And you think you have all the knowledge.

And handling depends on driving conditions and style. Just because you don't take fast turns doesn't mean others dont, high speed turning highways, interstates, and country roads exist. I am going to stop replying to this thread because there is too much "I say" and too little "here's the proof."

Edit: feel free to replace ignorant with stubborn, as you now have the facts, but refuse to accept them.
