I didn't even know there was a 295/70R17 out there until I saw this thread. That's the perfect size tire for our trucks if you ask me. 295s are 33 inches.
I called around looking for some and there is a nationwide backorder on them. Depending on who you ask it will be 1-3 months before they show up again. In other words, nobody knows.
In another thread, somebody said Toyo is coming out with that size. It is listed on the toyo canada website in the specs list for the Open Country M/T. Not the A/T though. And there are no size numbers or weight ratings shown.
