Thanks to others on this forum I learned of the Toyo LT285-75R17 Load Range E tire. It is an all-terrain tire. The tire is 2" larger in diameter and 1" wider than the stock LT265-70R17 tire.
I now have a set of 5 installed. There is no rubbing in the wheel wells and the spare fits, too.
I haven't hooked up to our 5th-wheel trailer yet so I can't say how the towing performance has been affected.
My GPS indicates that the speedometer now reads about 6% too low, which was expected.
