What is a good 35" tire, with Good Highway Manners, Has sipeing and is good in snow, and can be used to rock crawl.
I have the stock 17 Moab Wheels.
I also bought 16 Wheels for my winter tires.
What are the Pro's and Con's of
Plus what backspacing do I want?
I am getting the 3.5" RK Max Travel Kit.
GY DuraTracs are one of the best tires for snow, mud, slick driving conditions, on-road longevity, weight...BUT...I won't recommend them in this case, because of their relatively weak sidewall. Not great for rock crawling.
So I'll let someone else make the tire recommendation.
As for the wheels, like JEEPDON said, the alloys are much lighter, but can't be repaired if you bend or crack them. The steelies obviously can, but weigh a lot more. You'll have to decide whether saving weight or having a wheel you can potentially fix with a BFH is more important to you.
Smaller diameter wheels will be cheaper, especially when it comes to buying tires. It costs quite a bit less to put rubber on 15" wheels than it does 17" wheels. You'll also save weight, have more sidewall and a bigger contact patch with smaller wheels.
Be aware that most 15" alloy wheels will fit over your Jeep's brake calipers; most 15" steelies will not.
You want 4.5" backspacing or less on your aftermarket rims. The smaller the #, the more your tires will stick out from your Jeep. Again, size will make a difference here. Most of the 15's are gonna be in the 3.75 or less range, which means your tires will stick out past the fenders, whether the fenders are stock or aftermarket.
The farther the wheels stick out, the more stress they'll put on your wheel bearings.
