Hey all my name is Zak.

I own a 97 Jeep wrangler TJ amazing vehicle love it to death. I'm currently that into a project vehicle know. I just got a 2016 jeep wrangler unlimited 4 door back country edition. I'm loving it. I bought brand-new 33 inch razor MT for my old TJ. My new one I would love to put those tires on my new one but it doesn't have a lift on it. I've read alot mixed views and been told alot of different things. My question is or advice. Do I need to put a lift on my new jeep to be able to fit that razor MT? I do some light off road since I do live in montana. nothing crazy but that the old is going to become eventually. Any help/advice would he helpful.
 
Assuming everything is stock, fenders, rims etc. I think they will fit height wise, but most likely will rub something at full turn. Also not sure but the rear may rub the sway bar links depending on the width you get. For the turning you may be able to put a washer or two behind the turn stop bolt.

I have 33" tires and can get a set of 35" tires which have the same weight at 62lbs each. I know increasing tire weight adds more stress to parts, but if you can do a taller tire with the same weight as a smaller one, would it not keep the stress level on the Jeep the about the same?

One thing going to a 35 could mean a gear change depending on what gears you have now.

Not necessarily. Think of a lever arm - the longer the arm the more force you can apply with a trade-off of distance. With a larger diameter tire you are working against the lever. You also have to consider the force of impact if you are driving off-road which is increased by the lever. Now, this is all theoretical... You are increasing 6% from a 33 to a 35 so all will probably be fine...

Makes sense. Although by sticking with the same weight as 33's at 62lbs vs going to heavier 35's @ 67lbs that should help substantial I would think?

Also running 4.56 gears.
