All looks like red oak to me. White oak has bark that kind of looks like little potato chips you can flick right off with your fingers. Also, when it gets bigger, I find red oak to have much deeper furrows in the bark.
From the pictures, I agree, it's hard to tell. Some of the smaller rounds have distinctively red heart wood but the bark is more consistent with white. This may not help determine the variety but I looked up the difference in my Dirr book: White oak bark on old trunks is light, ashy gray often broken into small, vertically arranged blocks and scales. Older trees have deep fissures with narrow ridges; sometimes with rather smooth, gray spots.
Red oak bark on old trunks is brown to nearly black and broken up into wide, flat-topped, gray ridges separated by shallow fissures. On very old trees the bark is often deeply ridged and furrowed.
I'd put money on Pin Oak, which is technically a red oak. Most red oaks don't get so wide - I have 75ft tall red oaks on my property that are only half as wide as that - and has deeper furrows in the bark. Smooth bark in CT is almost always pin or black, and I don't seem to see black oak much.
Guys The leaves are in some of the pictures it's pin oak for sure . The difference between red and white is very easy to spot once you've compared them a few times . Pin oak has pointed leaves ( and narrow loves ) the red oak family has pointed ends too but fatter wider leaves. ..while the white oak has radius round leaf ends . Most oaks keep much of their leaves till December so leaf identification is easy to spot usually . The bark is noticeably different between the two and grain is too . It's one if those things where you just have to familiarize yourself by looking at pictures and the bark is another easy difference to spot
