That's probably just the SRSTV client not re-downloading your skin because the folder is the same age. Copy your folder to the skins directory, delete the original, then rename the new folder to be the correct name and SRSTV will redownload your entire folder, including your new rims.

Thanks for that suggestion, I am gonna give it a try 

EDIT: Worked like a charm, thank you!
