BKT doesn't shine tires for anybody who buys them. They're just so shiny because they're a smooth, unscratched, un-abused surface that can be plastered with tire shine to make look shinier than glass. EcoWork tires can look the same way to as long as the treads aren't chewed up and chopped up, but a lot of them are after the rule came in place to trim the corner off of the treads for safety purposes.
