35's with 4.10

First off I apologize if I missed this, but I spent 2 hours searching different forums (instead of working  ;D) and didn't find a clear answer.

I have a 2007 JKU X, Auto, 4.10, D 44 rear, D30 front (w/ eaton e-locker), TF 2.5" coil lift. I currently have 285/70/R17 Cooper AT 3's (closest to a 33" I could get on stock wheels per the garage). I got a good deal on a set of Pro Comp 17x9 wheels. Can I run 35" tires safely?
These would be mostly trail tires/wheels (mostly trails and mud, no rock climbing).
I have a superchips tuner so I can make adjustments as well.

It won't be the best but it will do I ran 38's with 3.31gears for a year so since they are trail only iI say go for it

The auto is more forgiving than a manual. It won't be a great rock crawler, but it doesn't sound like you want that anyway so you should be fine. If you find you want a little more lower end after you put the 35s on you can save money for that upgrade later.

It will be under powered but you will be fine for a daily driver. My 09 Rubi unlimmited 6 speed did ok on 35's with 4.10's but regeared to 5.13's later and now much better. No matter how u look at it the 3.8L is a gutless turd. The new 3.6L is so much better the you could run 37's with 3.21's and still have plenty of power. Just not a good crawl ratio.

Awesome! Thank you very much! The 3.8 does feel sluggish but thankfully the tuner helped a bit. Even with the 33's if I drive "easily" I get decent fuel mileage.
