34-35 tires and 373 gears

anyone here running this combo. either stick or auto? I have a rubicon now, it is a 2008 it is almost paid for, when it is paid for I may have to sell to by a house I need the down payment. while i love the rubicon the reality is I may not be able to afford one next time around so I was considering ordering ( when that time comes ) a sport but with 373 my ultimate purpose would be to build a daily driver with very good ground clearance go anywhere often alone and get out self reliant. and a winch. with the locker I have now I have never needed a winch but without lockers I feel it is a must so the gears remain the big question what are your thoughts?

so of you who are driving non lockable jeeps have you been stuck?

My 2013 JKU was 3.73s on 35s. It did fine as a DD. Some hills I would have to downshift, but it wasn't horrible. It was a 6 speed.

Not a bad combo for a DD with some average (is there such a thing) wheeling. Make sure when you do order it, you get the anti-spin diff as well

I ran that briefly in an early bronco with a 5.0 v8. It was a gutless pig and the transmission always ran hot. I put 4.88s in it and the trans cooled off and it became fun to drive.

If you want to keep the vehicle as capable as it can be, I recommend (285/75-17) tires as the biggest with the 3.6L and superchips flash. My brother has 275/70-18 (advertised as 33.2 inches) on his '13 sahara with 3.73, it is flashed and has a cold air intake. It is fonctional, but any bigger, you would be fooling yourself trying to convince people that it works well. No way.

I have 285/70-17 on my 10A Rubicon and it is flashed with flashcal, and if I decide to run 315/70-17, I would get 4.56 gears.

I have a Sport with 3.73s and 33" tires with an auto. I'd say with 35" inch tires based on my wheeling (higher altitudes, lots of long distance highway driving to get there, hills, back and forth across the Rockies) that a gear change with 35" tires would be mandatory, as it is, I am contemplating moving to 4.56s. I've read a lot of 35" are fine with the manual transmission crowd but is usually said in the same sentence with I lost use of 6th gear. Well, in my book, if I've lost 18% of the capability of my transmission that is a no-go.

I have a 13 jku auto with 3.73's and I am running 285/75/17 toyo's. I have no issue with the performance. I drove it on a 2600 mile round trip from Florida to Virginia last year and got about 18mpg. I did not notice the downshift issue and I came from a 3/4 ton Chevy with 4.11's than downshifted a lot more for about 9 miles to the gallon. I chose this size to keep them under the fenders. Offroad I have not had any issue, the only time I've been stuck was towing a boat in deep mud while turning a corner, I don't think lockers would have saved me there. I will say that if I was going to tow over about 2 thousand pounds consistently I would want better gears same for going to 35's. Tall and skinny is your friend and I would never chip my motor, your just asking for problems long term.
