Just purchased a 2015 2 Willys

I have a 4" Lift and 20's and 35's right now but thinking about messing around with a set of Goodyear MTR 38x14.50x17's. Mostly just a weekend toy around town and on the trails every once in awhile but nothing heavy. If I go to the 38's I would regear almost immediately. Don't mind my current 3.73 setup with the 35's for now. Has anyone else done this? Will I be fine as long as I'm not heavy wheeling or daily driving?

Pic is my current setup. Would still keep my current wheels and tires but the idea of 38's on a 2 door has me interested and I can get a smoking deal on the tires.

 

Sell the 20" wheels spoils the look of the jeep.... Sad

 

Thanks for the input... Good to know.

 

What axles are on your jeep? Why 14.5" is that the only size with the killer deal? vs 12.5" or even 13.5"

 

Lol, you are going to get the typical "can you vs. should you" replies to this. Yes, people have run 38's (or larger) on stock d30's. Some have had issues, others haven't. Reading through the various threads, you will see that some choose to beef up the axles. Some have destroyed axles and then replaced. Some have replaced before destroying so they could sell the stock axles. And others just push their luck and 'hope' that everything will hold together. You'll have to decide what is right for you...

Make sure the new rims have a low enough backspace, and/or plan on running adapters also. You should probably go ahead and price out all of the replacement parts (joints/hubs/shafts/etc) just to know ahead of time for if/when you have problems.

 

D30's. 14.5's because that is what the deal is on.

 

That tire has the same fitment needs as running 40's because of the extra width. You are going to find it difficult to find wheels with low enough back spacing to run them of factory axles even with adapters. Ball joints and unit bearing are not going to like them either and plan on lots of maintenance. If you plan to take them off road you will want at least hydraulic assist on the steering as it will be very hard to turn those tire deflated.

 

I definitely understand that in the long term there can and most likely will be issues. Not planning to go wheeling hard enough to destroy axles. A trail or maybe a mud hole every once in awhile will be all. Given the normal timeframe I keep a vehicle it will be gone well before the tires need to be replaced... The main part of my question is as long as it's driven more on the road and wheeled hard should there be any issues up front... If the backspacing on the wheels is correct I believe I can get by without spacers...

 

Listen to nthinuf and dirtman's advice they know what they're talking about

 

When you say lots of maintenance... 5000 miles, or 20000 miles... Or does that depend on how I drive it and where I take it?
