The Daystar lift is not a body lift so it actually gives you additional ground clearance.
With the 1.5" Daystar lift you can use up to a 30" tire. 235/75/16 is a 29.2" tire, but you will need to check on the clearance between the tire...
The Daystar lift will give you 1.5" of lift regardless of what model you put it on.
