They're mid range as are hankooks in the tyre community.
Tyres - well, always a fascinating topic.
As someone with more years in the tyre industry than I care to admit too I always enjoy reading other peoples opinions.
Originally Hankook were budget tyres and Uniroyal were premium but over the years their owners changed and re-positioned them in the market place.
As an example, Michelin & Continental wanted a cheaper tyre to sell to compete in the lower priced market. Michelin bought Hankook and used them for that purpose. Later they thought 'wait a minute'. if we only sell these through certain retailers they can become an 'in-house' brand and can be sold as a mid-range product thereby increasing our margins. Continental bought Uniroyal (Europe) and re-positioned them as a secondary line (mid-range) to their named brand. At that point these were still the same Hankook & Uniroyal products but just re-positioned in the market place. Over the years of course things have changed. As a rough guide now the 'company named brand' gets the biggest investment and latest technology in tyre construction and the secondary lines get 'last years or before' design/technology to save money. Nothing wrong with that depending on your requirements. I should add all major tyre brands work on similar lines with some having multiple brand names in their portfolio..
So ..... would I fit part worns - sorry but no, there is no guarantee where they have come from. Some European countries have laws which mean they have to be removed at a tread depth where they can still be used in this country, but someone on the forum bought one with 6 or7 mm on (sorry can't remember) - you have to ask why was this tyre removed. Could be a perfectly reasonable explanation, or there could be cord separation inside the casing after a car accident and you cannot see it, but the point is you just don't know. I do know one company, and there are probably more, that x-ray the casings before selling which should pick up any hidden damage but again there is no guarantee the tyre you are buying has been through this process, and it also increases the end cost. Personally I always fit premium brands, as the only part of the car in contact with the road I feel my life is worth the best. It always amazed me that some drivers would skimp on their tyres and yet spend £100's on a new audio system for the car - different priorities I guess.
There are many tyre comparison website (just google) where tests are conducted on all sorts of new brands and well worth looking at if you see a tyre at a bargain price somewhere. Just bear in mind that one persons requirements can vary wildly to anothers, although safety really should be on everyone's agenda.
Nothing I have written makes me right and someone else wrong, its just my opinion.
(btw. Hankook are no longer owned by Michelin)
