No lift or leveling kit yet. I bought an Alu-cab Canopy Camper that will be installed next spring — waiting on that before making any suspension mods.

I'm still waiting for spring to arrive before I pickup a set of these. Do you know what they measure when mounted? Thanks

What is the most common "larger" tire size that will fit on the stock Sport S - Max Tow rims? Obviously it's 245/75/r17 as OE but I'm not 100% familiar with how proper upsizing works.
I'm considering getting Falken Wildpeak A/T3W tires before the wet/snow season hits Ohio but I'm not 100% on wanting E rated tires. I'm 85% highway as a daily driver so not totally messing with my fuel economy, being quiet, and good stopping distance (wet & dry) are my main priorities with a desire to just look more aggressive than the dueler OE tires.
Reprogramming for size won't be an issue as I'm ordering my Livernois tuner early next week.

Thanks for any advice
i have a sport with max tow and the first thing i did was put 35s on there they are good for you if you dont want to lift your truck but they also work if you do. i have a 2in lift on mine and they still look big on my truck.

I had 315 70 17 BFG KO2S and January moved up to 37 12.5 17 Goodyear Kevlar MTRs. I'll say this I love the look of the 37's but I'll probably buy a set of A/T's in 37 when I wear out these MTRs. I love how the MTRs look but coming from the BFG KO2s to something like the MTRs you notice a difference in the ride quality. I'm going to put on some Geo Brackets and a adjustable Track bar to see if that helps. Also mpg wise I'm at 16.5 right now and I was at about 18.5 on the BFGs but that's expected when going up in size. I'll see if the MPGs get any better or worse as I drive it more. Here's some pictures of both

Loving the photos everyone. When I do eventually upgrade I'm thinking i'll be going 33"-34" (either Falken ATW3 or Toyo AT3) and either a 1.5" / .75 level or the Clayton 2.5" RideRight depending on fit. I won't be offroading so I don't need to go huge - but I do want to make sure everything fits.
Playing with my budgeting spreadsheet I've realized this is an expensive hobby to get into XD (And I'm loving my first Jeep!)

Went with 2.5in Rough country leveling kit (coil springs) 1.75in wheel spacers, and 35in BFG km3. May remove spacers in future to see how it looks. 🤷🏻‍♂️

Lift and tires look awesome! Ive never been a fan of an aggressive bull dog look personally. I have 1/4in spacers on my wheels now which gave me a little tire peeking out. I have 1/2in once sitting at the house, just haven't stuck them on.

yep, same problem for me. The combo of the wider axles on the JTMT and the little 1/4in spacer has my door hinges completely coated with ice this year. kinda annoying.

Looks good, do have a Max Tow or Regular sport/Overland because if you remove the wheel spacers on a regular sport or overland with stock wheels you will hit the lower control arms at full lock. Here is a idea of what it would look like with spacers removed and installed. I'm running 1.75" spacers on mine with a 2.5" ReadyLift also was running BFG KO2S in a 35 before going to the 37's included some pics for your reference

No lift no wheel spacers

Thanks for the detailed response!! Your tires don’t look like they stick out as wide as mine do, maybe it’s just me haha. My gladiator is one big optical illusion. From one angle it has some squat, other angle it’s nose diving.. tires look big up close, look stock at 20 yards away hahahah. What am I to do 🤷🏻‍♂️

Yours looks great man! I need 37s 😐

Yeah I thought my 35's looked big until I went up to 37's, now I'm hooked. I get what you sayin though 100%, feel the same way about mine. Every angle looks different, worst angle is looking at it from the rear, I'm still trying work on that. I almost got it where I want it at right now though with the overall look.

I agree! Yea from the back mine looks like it’s nose diving haha. I’m considering a slightly larger lift in the near future and I think that will help. And some big ole beefy 37s too!
