i'm going to be ordering a set of these rims for my truck from
on where it says rim size it says 15x7 15x8 and 15x10 how do i tell which one to get? I know i have a 15 inch rim stock on my truck right now but what does the 7,8, and 10 mean? which one do i buy.. thanks for the help
also how often would i have to clean these rims? i will be driving this truck in the winter which = salt all over the roads. will they carode easily?
