Have you considered Q. falcata? Leaf shape is within the variability of Southern Red Oak and it does have pubescent leaves.

I'm not very familiar with falcata, but the leaves don't look like the few falcata I've seen. Leaf shape is more like shumardii (or maybe nuttallii?), but I didn't think those 2 species have the pronounced pubescence.

Here's another shot of the leaves

Agree the trunk suggests pin or northern pin, but the leaf shape isn't right and I don't think the leaf/twig pubescence is typical for pins or scarlet, black, or shumard. The leaf shape is like some shumards I've seen, but isn't typical for scarlet or black IME. Maybe a hybrid, but the several trees we have all look the same. Pretty sure they originated in the south, probably TN.

An oak of mine was supposed to be Shumard, but it definitely has something else in it -- my guess is Nuttall. Bottom line is I, and you, both have a nice oak from the black oak family. Acorns eventually might help ID, but mine at 15 yrs old and 30' tall still hasn't produced a single one.

Revisited the oaks in question and took a couple more photos. Pretty sure they are Cherrybark Oaks (Q. pagoda ), formerly considered a variety of Q. falcata. Lower leaf surface is very pubescent. Apparently there is a grower(s) in the south that is selling these as "red oaks" to wholesalers in my region.

Looks quite different from plant in first two photos to me. If you haven't done so collect specimens from these and hold them up next to the tree in your original post, this will make it apparent how each stacks up in comparison to the other.

It looks foreign to me (not minnesnowten). :)

Should be nice trees if they survive your area.

It's probably hard to believe, but all the photos are from the same tree. We had 5 of these planted at various locations in the spring of 2018. Leaf shape is actually fairly consistent from tree to tree, but the shape does seem to vary a bit from year to year, perhaps based on weather and growing conditions (we had a hard freeze in mid May this year). What is very consistent is the relatively glossy upper leaf surface and densely pubescent lower surface which is characteristic of Q pagoda. The leaves also tend to agree with this description from Wikipedia: "The species is unusual in that the lobes are not necessarily paired on opposite sides of the leaf, instead appearing alternate or sometimes haphazard in arrangement "

Very handsome leaves, remind me a bit of black oak (variable, rather leathery, glossy-top leaves). Hardly ever see black oak in the nursery trade (maybe 1 time), but you never know....
