RE 4.5 SF lift and tires question

Bought my jeep about 2 weeks ago and last night I ordered a 4.5 RE sf lift, sye kit, and a tw drive shaft. decided to buy this after i went wheeling yesterday and almost got stuck a few times. Where i live in new jersey you have to go through alot of deep sand to find any descent trails. 30" AT (well hybrid, mostly street tires) just dont cut it.

so my questions: how big of a tire can i run with this? I know i need something wide to go over the sand and i know i will need new rims for the wider tires so that i can still turn. any suggestions? how do i tell what spedo gear i need?
also, any install tips for the lift or sye? done plenty of motor work and some suspension work but iv never torn a t-case down even tho it seems really simple. i think i will get a new chain for it while im at it.

any thoughts, tips, suggestions will be appreciated. this is the first in a long line of things to be done to this jeep. my list also includes an aev highline kit, a chevy v8 swap (im thinking an LQ9 truck motor), d44 up front, and selectable lockers of some kind (probably arb). this is not my dd but i do drive it alot so i will keep it streetable. i will try to put up some pics of it tomorrow when its light out and will definately put some pics up when i put the lift on.

35x12.50 will fit just fine, you may need to extend the bump stops a bit more than what comes with the kit, but flex test it and see. I ran mine with 2" spacer in the front to make up for the winch. I ran 15x10 rims with 4.25 back spacering so it would fit on my trailer.

thanks. i dont know much about backspacing, guess ill start reading some stuff, but i want to make the wheel base a bit wider to make a roll over less likely. i might even go with wider axles if i have to.

You have to really work to roll a TJ. The axles in the pic are prorock 60's 1" wider than stock. here is a better pic to give ya an idea on how far they stick out.

No worries on rollovers unless you do something really stupid. Aftermarket wheels have less backspacing which means they will stick out further which is enough to compensate for a typical (like your RE 4.5") suspension lift's added height. Go for 15x8 wheels that have 3.75" to 4.5" of backspacing and you'll be fine. There's definitely no need for wider axles for that reason.

Edit: 4Jeepn, what was wrong with your winch where the cable was laying loose all around it?

ok thanks, wider axles would have been the last thing on my list anyway. i found a set of Dakota Definity M/T 285 75 16 tires (made by cooper) on steel wheels with a 4" backspacing and 5 on 4.5 bolt pattern for $275. by my calculations thats about a 33/11/r16 tire. I know its no where near the best tire but im thinking that for now it might work out for me and let me get the v8 swap done quicker, mainly because i found my v8. anyone know how those things do in sand? mud? street? the guy says theres about 1000 miles on them and im inclined to believe him since there is so much tread left.
the v8 that i found is an lq9 (an LS2 with a bigger bore and an iron block) with 50k on it for $1000 with wiring harness and trans. its in an Escalade that had an interior fire and got all messed up. i am going to go and pull the motor monday or tuesday and it can sit in my shed until i find time to do the swap. i just cant pass up on it for that price. i think it has a 4L60E trans but i might try to find someone that will either buy the trans or trade me a th400 for it.

i think once i put the v8 in i will have to end the spending spree for a while so i dont run out of money tho.
