Until I saw your post and viewed the YouTube video on rim blades, I had never heard of these (flexible plastic trim-to-fit covers that are installed over the rim of your wheel to help protect it from damage). It seems like these would help prevent light curb-to-rim contact. Once the rim blade gets scratched, it's easier and cheaper to replace than an entire wheel. They can also add visual "pop" to your ride if you choose an accent color. They obviously won't prevent rim damage from heavy impact (like running over a perpendicular object too fast) or from those drivers of your car who have no idea how to parallel park.
- get tires that have "tire rim guards" which is extra rubber that extends the sidewall of the tire. The tire makes contact with the curb first, not your rim
- don't get tires that are too skinny for your rim
- use your RH side view electric mirror and aim it down to your right rear wheel when you park (if you need it)
It's a fun look and may possibly help. Good luck!
