I think a brand name and properly installed body lift would be fine for this application, and likely the easiest and cheapest.
A "75 series" doesn't say anything about how many inches tall a tire is, that is just the aspect ratio which depends on the width and rim diameter (how tall it is compared to the width).
I.E.:
235/75R15 = approx. 29" tall, 9" wide
285/75R16 = approx. 33" tall, 11" wide
Both are "75 series" tires but quite different in overall size.
