I am also thinking 35" as the look in awesome. My biggest concern is that I have an Unlimited X Auto. With the front D30 handle the 35's weight wise.
I will do some off road. Probably more trail rides and mud, not a lot of rock climbing.
Any input on lift is appreciated?
The new D30's are more like the old D44's in strength...and the old D30's were even ok with 35's if you were not stupid with the go go juice....
...so, similarly, the new D30's should be fine with 35's.
If you live where its very hilly/mountainous, etc...gearing might be an issue...if you have the 3.21's...yes, with 3.73's, most of us flatter landers are OK, as 35's are only a little taller (~ 8.6%) than the stock 32's, etc....if really sloped terrain, well, lower gears always are better for torque/worse for mpg.
(For comparison...if you got 3.21 diffs instead of 3.73 diffs, that ALONE would be a ~ 13.9 % change, etc...)
And, its not so much the WEIGHT difference, as the LEVERAGE DIFFERENCE with a taller tire...as the imagined lever arm from the center of the hub to the ground is longer, requiring more force to propel you....and, exerting more force on your drive train, etc.
The weight plays a role, but its secondary to the force multiplication affect.
