I'm on TRD lowering springs with 18" wheels and 225/40. The ride is hard, but I wouldn't call it bone jarring. If you hit big bumps, you will rub. If you have 300-400 lbs in your trunk, you WILL rub with any bumps. If you're going to carry something in the back, go with 17" or roll your fenders. Z. Did I post this on the wrong thread? I thought I was posting on a thread about someone asking a question about their Prius on a TRD springs and 18" rims size. That post is gone. Hmm... Strange. Z.
thats @Sandog53 ! A little update on my 2010 Prius! New Wheels, new color! | PriusChat not sure if he still has it. I think he got a Focus. Matte-colored Prius's are still in my top 3 as well.
