not long ago I got cut off by another car, and drove onto the curb-resulted in bent rim.
Mine has 18" 6 double-spokes (12 spokes), appears as silver color. However, when I looked on-line, I saw two different colors-one is "painted silver", another is "Chrome" rim.
How do I know which one I got?

Thanks a lot

Sounds like yours are the 18" HSE alloys like these:

I would say that they were Chrome rims.
Show us the website you saw showing the 2 different colours and I'm sure someone will confirm this.

yes, they are the same as in that pic-anyway, I found a "local" (about 1 hr away from me) shop that fixes the rims- next week I'll go there, and they will tell me if it could be fixed and how much.
