Yes a heavy wheel and tire combo puts more stress on all parts associated with being attached or moving them.
Balljoints, bent housings, bent/broke axleshafts are usually the first casualties.

Highwayman is correct, but your tires are not extremely large, and your lift is not extremely high. The extra wear and tear will happen, but the worn parts will not show up right away.
Bigger tires do make the Jeep feel sluggish with 3.21 gears, but that will not hurt anything very much.

Dyno Run - Effects of wheel/tire weights on wheel horsepower | Flickr - Photo Sharing!
Check out the link above, this has a great Dyno run show the loss of rear wheel hp with the addition of unsprung weight.
This is a 2012 camaro but the principal is the same for our jeeps
1. (Blue curve) Factory wheels: 20”x9.0” with Pirelli 275/40-20 tires weighing 68 lbs combined per rear wheel. – Max hp: 371 hp, Max Torque: 375 ftlbs - (Baseline)
2. (Red curve) Aftermarket wheels: 20”x9.0” with Pirelli 275/40-20 tires weighing 72 lbs combined per rear wheel – Max hp: 369 hp, Max Torque: 373 ftlbs - (A [-] loss of 2 hp and 2 ftlbs)
3. (Green curve) HRE wheels: 20”x11.0” with Nitto 315/35-20 tires weighing 60 lbs combined per rear wheel – Max hp: 380hp, Max Torque: 384 ftlbs - (A [+] gain of 8 hp and 9 ftlbs and that is running a 2” wider wheel/tire combo)

There are threads about gussets, etc. that serve to beef up your axles. Do a search and you will find what you need to do in order to feel safe about your weight. Also, the main thing that will cause breaks in your axles is your rotating mass - namely your wheel/tires. Things like bumpers will not cause that much additional stress, as they are not rotating.
