I'm running the same setup and i'd have to agree with you on the mileage. I don't calculate it regularly but i'm definitely getting 12 or 13 around town and prolly about 16ish on the highway.


Mileage will most definitely drop off with 37's. That's a lot of rotating mass to get moving, even with the proper gearing...no way around it.

13 at best in town and 16ish on the highway... Hmm, that is definitely a consideration. I appreciate the input guys. Thanks

Have you had them off road yet?
That is what I want, must put a 4" teraflex on my 09 JKUR. Just trying to decide if I want new rims too or stick with the stock aluminum 17s

Btw I've been meaning to tell you, sick ride! I love the black/red scheme you've got going on.

you should be fine in the 12-14 psi range... going beyond that is pushing it on a stock rim and having it unseat on trail is something you don't want to experiece first hand.

Is everyone here running stock axles as well? I was worried about going up to 37s on my Unlimited X because of the axle problems?! Am I safe or should I just go up to 35s?

Im not a fan of the Toyos. They are super heavy and need to be rotated a lot. I dont know much about the Nittos, but out of those 2 choices Id try the Nittos.

The mud grapplers are really heavy not sure about the trails

These are basically the same exact tire, look at the tread pattern and weight. They practically mimic one another and not to mention they are made by the sister companies so there is really no difference in the long run. BOTH are heavy ass tires.
