15 x 10 tire suggestions

I have a set of 15 x 10 x 7 5/8 BS.

I am looking for some 27 ~ 28 inch tall tires that will fit on the wheels without a bunch of sidewall bulging outside the wheel lips.

I will admit I have always thought backspacing and offset is sorcery and I never really have understood it. These wheels seem to fit pretty well.
