Michelin Primacy 4 should be your best choice.

UC6 is low end model from Continental while PS4 is high performance model from Michelin which is 2 levels higher in category. Comparable Continental model to PS4 SUV is CSC5 SUV which maybe even more expensive since it's still made in Europe. Continental if top end models like CSC series are excellent tires that go toe-to-toe with Michelin high performance models. Low end models like UC6 though is tire asal jalan saja. I personally won't buy them. Anyway huge 19' tires, what do you expect on the price? Good tires surely will be very expensive for such huge size.

Hankook has often matches those other brands and I noticed recently in the Tyrereview UK website they are now included in the top tier premium brand category already, overtaking even Yokohama.

Toyo though only occasionally can match the best of those other brands, more often still below in most comparisons I have noticed. If prices of them can be much cheaper than those premium brands then maybe worth to try but if almost similar then better not.

Firestone not sure, not quite popular here anyway. It's an old rather popular brand in the US as part of Bridgestone sub brand, so maybe decent but theh don't seem to have offerings that can match the max performance category of the top brands like PS4S, CSC6, F1A5/SS or PZero PZ4.

Kumho though, not really. Never heard or read anything good about their products. Surely way below what Hankook has been able to deliver.

What size?

Michelin Primacy SUV.

Goodyear Efficient Grip SUV.
