Bottoming out with 33’s?

Just got some new 285/75/r16 tires. I have a stock suspension 2015 S. I haven’t put the new wheels on yet. I plan to put 1.5” spacers on as well. Will I bottom out with these tires? I know they technically will fit with a melt mod but if I’m roughing it on some Colorado trails this summer I’m curious if I need to add a lift.

Question 1.5: will a leveling kit help from bottoming out, will a body lift? Or do I need to go full suspension lift? I’d prefer to go all the way but can’t afford that right now so whatever cheapest option will allow me to clear is good right now.
