Gear/tire size opinions
I have an auto JKU with 3.73s and a 2.5" RK max travel suspension...upgrading the tires and wheels soon.
Questions:
A) How hard will 35s be to turn without regearing? There are some steep hills going in and out from where I live and I don't want to have to creep 5 mph up the hills to get out day after day
B) Will the AEV savegres rub the rear swaybar links?

What year is your rig?
If you have a 2012/13 I suggest you review this thread.

Even if you have an older jeep the above link will be helpfull.
07-11 generally people with 35's go with 4:88 or 5:13
12/13 you should go with 4:56 or 4:88

I'm going to guess that your JK is not a 2012 since you became a member in 2011. Plus if you had a 2012 you would not have an issue with 35s and 3.73
My JK started out with 4.10s but I had her weighted down with lots of mods. I had no problem driving up fairly steep hills but you may speaking of steeper than what I drove on. I took my JK to Pigeon Forge, TN and there are some pretty good hills along that route. The only catch was I had to have my overdrive off at all times.
3.73s aren't 4.10 but I think with your overdrive off it will be bareable.

Per this link,
Calulators from www.4Lo.com
If you have 31 inch tires now with 3:73's going to 35in tires will in effect lower your gear ratio to a little better than 3:21's. You will have very little torgue. On average there is a 3.5% torgue loss for every inch of tire you add. 4x3.5 = 14% loss in torgue.
