The Continental Explorer looks like a very aggressive tire. They are pretty low end tires though, so the compound might not be the best. And being you need 26" tires, there aren't a lot of high end options. But in any case , better gripping tires are not going to be fast at all, like I suspect the Explorers are probably really slow.
But based on the fact that these berms have loose gravel, I don't really think this is a tire issue but more of a technique issue. If you have bad technique or are just riding too fast you are going to wash out on loose gravel no matter what tires you have.
