Tire Size Dilemma on Budget Boost

About to put on a Rough Country Budget Boost 2.5" (w/ shocks & steer stab) on my 2012 JK 2-door.

Looking at 17" wheels: 8.5" wide w/ 18mm offset.

Now the part where I'm torn....

305/65 (~32.6x12) vs. 35x12.5

Considerations???
- RC says 35s shouldn't rub (much?)
- GAS MILEAGE???? (obviously, this is a daily driver)

Any input from the JK community is greatly appreciated!

Hope you got your radio issue sorted. You've been on the board for a while, you know how it works. ..have an issue, do some searches, ask a question, report results.
All lift and tire questions need to include the type of wheeling/driving you do incl. terrain, conditions, frequency etc. Is this for looks or wheeling? GiGo.
I see you skipped the search part so:
Tires and lift. 33's look small with 2 1/2 inch lift but offer decent wheeling and won't rub, minor milage considerations. (Flat highway mileage may even increase slightly if your rpms drop due to increased dia.)
35's are sometimes 34's depending on wheel width and manufacturer but with RC prolly will rub on fenders later, no big deal, it's just noise.
Milage. More weight, more rotational mass, more money, more gas. Wear and tear on the unit bearing and ball joints.

Please use the search feature also. Your questions have been discussed many times.
Search "will it rub"

Wow! you must have some great research tools or I just need to delete my cookies like your avatar suggests. I've read up a bunch but mostly through google searches (not logged in). Good suggestion with the "will it rub" search.

Also, thanks for your input! So I'm leaning 35's. (even the wifey said "go big")
No intention to go to flat fenders, so I may have to adjust steering stops (I'm assuming JK's still have this like my old TJ, I guess I never actually looked)

I had some long term concerns about durability of ball joints, etc. But this thing is 90% highway and streets, but it gets out on the trails a handful of times a year and have been known to bury it in mud here and there. lol

You can add washers to stock steering stops, you may not need to with 35's.

Just a follow up....went 35's on 17 inch rims w/ +18mm offset. Makes it ever so slightly beyond flush with the wheel flares. Got a little rub with the plastic skid shield, chose to cut a bit off the plastic shield, so no need to adjust steering stops.

FYI..this lift kit did NOT come with longer front stab bar links. It did however come with longer rear stab bar links, so I just put my old rears on the front. It also called for re-use of the old front track bar, which would have shifted the axle laterally to one side, so I chose to order an adjustable track bar and get it centered again.
