Gentlemen,

I currently have a 2013 Jeep Wrangler Rubicon Unlimited 10th Anniversary, automatic. I have 35s with a 3.5 inch lift on it.

I’m in the market for new tires as mine are getting old.

I was thinking about jumping up to 37s. I’m sure there are many threads on this but what do you recommend, if anything, to upgrade to have 37s.

This is a daily driver and the jeep does not really go off road, just maybe some dirt trails, if that. I just can’t get over the look of 37s. I don’t have a huge budget either.

Thanks in advance.

 

I would have to think 35s with the stock 4.10 gears would be slow as heck. 37s on 4.10s would accelerate about as slow as watching grass grow. You'd have to be into the throttle so much, it'll kill your gas mileage.

 

that's a lot of money to spend just to "look good" with 37's . You might want to go ahead and search those threads about adding 37 inch tires, lots of solid advise there - that people still don't listen to. BTW what gear ratio are you running ?

 

oops, I see it now ... not much gear for 37 inch tires...

 

At the top of this modified section is a sticky about 37s. You should read through it. The glaring thing in your original post is "I don't have a huge budget". I would say that is a hard pass on 37s IMO. Doing it for just looks makes zero sense to me considering all the effort with any modified rig is keeping nice pavement manners. Your gearing will suffer, your fuel economy will suffer, your braking will suffer, your steering components will suffer, and your wallet will suffer. Can you still do it? Sure. It will work, jeep won't blow up but things will be less than ideal and you will feel the pinch in your wallet, if not immediately, over time.

I'd add that when I first went to 37s I ran a 37x12.5 Nitto TrailGrapper with stock rubi axle with 4.10s. You get by for a while being happy with it, telling yourself that the gearing is fine cuz the 37s have glossed your feelings a bit. I always knew I was going to regear but was trying to make it as long as possible. I made it about 10 months, if I recall, before I was just beat down. It wasn't the "around town" type driving so much as it was the interstate driving that wore me down. Pretty much lost 5th gear on the top end, and if someone in the car in front of you farted it would make you downshift to 3rd.

If you're hell-bent on the idea, pick the smallest/lightest 37 out there. The mass at all 4 corners adds up quickly.

 

If you are going to go with 37's, make sure you upgrade your brakes first. Factory Jeep brakes suck bad enough on the factory wheels and tires, going with bigger wheels and tires adds a lot of rotating mass that is very hard to get stopped. I have the Dynatrac Progrips on mine and they have worked well so far. Although it is getting to be time to change the rear pads.

 

"I don't have a huge budget either" You will grow tired real fast. All the advice here is no unless you want to drop that huge money into axle upgrades, etc etc. For starters you get diminshed turning radius unless you replace with wider axles $$$$$$$. Will be that be ok in NJ?

 

I couldn't agree more. shoot,... with my 35's and 4.88 ratios, the jeep almost wants to push through the stock brakes and take off on its own when i first put it in gear in the morning and coming to a sudden stop takes some creative braking. Not ideal. I could't imagine trying to stop the extra weight of 37's.
