Are 33s too big?

I have a 2003 Sahara with 1 inch lift springs and 31x10.5x15s bfg ko2s that came when I bought it, along with a set of, (I think) 1.5 inch spacers gifted by a friend.
I will soon need new tires and I’m considering upgrading to 33x12.5x15s or potentially 33x10.5x15s, thought I’m leaning towards the 12.5s.
This jeep is my daily (about 10k miles a year, I’m a student so I don’t drive a whole lot), and I take it offroading about once a month, in addition to lots of rough roads to get to campsites often. I also live in western NC and get a good bit of snow, which the ko2s handle… passingly (not great).
Should I do the upgrade to 33s? How will this affect my gas mileage, service intervals, and on-road and off-road performance, will they even fit (worried about rub at flex)?
If I were to upgrade, I’m looking to move to a yokohama geolandar m/t g003, I live the look of them and they seem to have good sidewall tread.

You have 31x10.5x15 that rub to the point that you took the flares off, and you "feel like" 33x12.5x15 will clear?

Carry on.
 
33s with almost no lift will be fine. 🙄 Removing the flares doesn't help with clearance. 🤫

many will knot agree BUTT ...

current 2001 Sahara is only my 4th Wrangler w/ extensive ownership/mileage/experience in 2 XJ's as well easily totaling over 500k of Jeepin' (knot counting miles in family member's CJ-6, CJ-7 & Grand Cherokee)

w/ over 90% of usage on pubic roads that still has me having dunn several thousand miles on un-paved to absodadgumlutely gnarly byways it has been my experience that unless one has a rather deep pockets and a love for turning wrenches maintaining stock tyre/wheel size and wheel offset is paramount when trying to get the greatest number of miles for the least number of greenbacks

funny thing about manufacturers ... they will usually only offer tyre/wheel packages that will provide optimum performance and longevity frum the factory

sew ... if you start monkeying around w/ the geometry of the original design you can expect to increase your expenditures AND mechanical failures

wider tyres frequently require greater wheel offset which places rubber way on out beyond your fender coverage thusly flingin' farfelonous n feldergarb back down the side of the body of your vehicle leaving it's destruction in it's wake

the wider the tyre n wheel offset increases the leverage/forces on thingies like tie rods n trailing arm bushings & spindles ...

knot only are those larger tyres and fancy smancy wheels more costly @ buy in BUTT they tend to increase maintenance/repair frequency and costs exponentially knot 2 mention increasing down tyme

steering geometry is another element that takes a major hit in the equation and any bump steer will be exaggerated w/ over/off sized combinations

IF your vehicle is a 2nd unit and/or you have deep pockets AND really have to have those Tonka tyres n wheels for visual appreciation and you have a trailer to get it to n frum the play ground then step up to the lick log and begin flinging $$$ @ your Wrangler

in my days n weeks & miles of off-roading i managed to SAFELY traverse ENGINEER(avatar) , STONY , CINNAMON & BLACK BEAR PASSES as well as waded across the RIO GRANDE n back @ La Jitas, Texas in my bone stock(no suspension mods) 1995 2.5/5-spd YJ on factory wheels w/ factory sized tyres

IT'Z YOUR $$$ ... spend it to suit your desire & pocket depth

Jeeps are neat little vehicles that get S...tty gas mileage ;-)

be honest with yourself and don't get lead down a path you're knot up to traversing

b4 taking anyone's suggestions to heart make sure they fit your vision and pocket depth

btw ... my TJ is back on factory springs & body mounts along w/ Canyon rims w/ 30x9.5-15's and she runs n tracks GREAT !

BON CHANCE W/ YOUR QUEST !!!

I just desperately need something, if you scroll up you’ll see the picture of my rusted out front fenders, I also think the factory fenders look quite goofy without flares, but also aforementioned, the flares rubbed at flex.

It’s ok if the tires rub the flares. That’s why Jeep made them plastic, to move out of the way. It’s the fender seam that’s the issue.

So far a just tire choice, I’m running the Geolander MT G 03s and love them. Quiet on the road, especially compared to the Mickey Thompson’s I had before(& loved) and handle everything that I’ve thrown at them off-road.
