35s & 3.73 gears
I have 35's with 373's and an automatic and my performance is great. i'd imagine having a 6 speed and 35's would be more favorable.
Someone from an aftermarket dealer (not going to say who) mentioned to me that regearing from 3.73 on the new JK wont make a difference if you're running 35s. It only makes a difference on the TJs. Is that true?
I had 3:73 on an auto with 35s for 4 months and the damn thing was always downshifting on regular freeway ups and downs,when i got the 5:13s there was no more down shifting or having a hard time keeping your speed or anything it was smooth sailing, I love it and got alittle better mpg too

changing your gear ratio from 3.73 to 4.88 (or whatever) has the EXACT same effect on a JK or TJ or a 1972 Charger or any vehicle. Whoever told you that is an idiot

My wife has a stock 2007 unlimited auto with the 245x16's and 4.10 gearing. I think it's adequate at best.
I could not imagine the same tire with 3.73's let alone running 3.73's with 35's.
