Just bought some rims of ebay they are split rims 11x20s not a very popular rim as a rule unless you know what they are but for our purpose the are perfect very strong heavy and best of all can be fitted with run flats.
Main reason there not popular is they rust and when rusty they are difficult to split and indeed these are rusty, done two of them gonna get them shot blasted but wondering what to paint them with, needs to be hard as nails but thin due to the nature of these split rims, thinking about painting them with POR 15 used it before but I think it's best used on rusty metal to adhere properly.
Will put some pictures up when there done.
