I'm curious... What Hankooks do you have, and what safety concerns do you have? I have the Hankooks (DynaPro ATM RF10) on our tow vehicle for several years and they have been the best tires I've had on our truck; grip, handling, and mileage are great. The reviews I've read about them from others have been very good as well.
I've had the Yokohama Geolanders (which were OK but too soft with or without a load), Big-O tires, and Goodyear. I've been very happy with them. The Hankooks are a little stiffer than the other tires, but am very happy with them. When it comes time to get new tires, I think they will be these Hankooks again. I've had them in mud, grass and snow, and they've done very well in each case.
