Anyone swapped their 20's for 18" wheels?

New guy here...in fact haven't even picked up my new (slightly used) 14 JGC Overland EcoDiesel yet...Thursday hopefully.

While I love the look of the 20" wheels/tires, I am a High mileage driver (48K/year avg) and so I'm considering trading the 20's for the OEM 18", such as the ones that come on the limited version. This will give me a much broader spectrum of tire selection and and an overall savings on tires costs...which is a yearly expense for me. My questions follow...if anyone has any experience, or advice I'd really appreciate it.

1. I've not done the diameter calculations yet...anyone know offhand if the speedo will need to be recalibrated? Any other mechanical or software related issues I'm not thinking of?

2. Anyone with 18's....any tire recommendations?

3. Anyone with a Limited with 18's....interested in a trade? I am located in Columbus, OH, but frequently travel to Indy, Detroit, Cleveland and Pittsburgh areas....I think shipping would be a pain, and expensive.

Thanks everyone...

If you fit 265/60-18 tires, the speedometer will be unaffected.

I'd look for an all-season tire with the snowflake and mountain logo, such as Nokian WR3 or Toyo Celsius.

If you were closer to DC I would most certainly do a trade with you. I have the 18's on my limited and have been looking for 20's.

Glad to know about the speedometer. And yeah, I'd like to find a good "tweener" tire...one that had decent off-road ability, but won't kill me with noise and short tread life. Those Nokians are interesting....need to research those a bit more.

I could probably make that work, my sister-in-law lives in Pittsburgh so perhaps we could meet there, making it a bit closer for you. The earliest I could make it out there is September though. Any idea as to the general condition of the wheels and tires? Any pictures?

I bought my Jeep ('14 Overland) used too. I took the 20's off, and put 18's on, but to be clear mine started with 18's before the original owner put the 20's on (18's are part of ORA2 package). That really doesn't matter though since they can all fit 18's. Point is, yes I've replaced 20's with 18's.

To answer your questions.
1 → this depends on the tire size you buy, and is completely unaffected by the rim diameter. As previously noted 265/60/18 will be the same tire diameter as your stock 265/50/20, so the speedometer will be unchanged. FWIW, I am running a 255/70/18, which is about 1.5 - 2" bigger than stock. My speedometer was off by roughly 3 mph at freeway speeds. Most tuners, or a dealership can adjust what tire size is used by your computer by plugging into the OBD-II port. 5 minutes, and you'll have an accurate speedometer, and odometer.

2 → I'm running BFGoodrich KO2. Another great tire is the Goodyear Duratrac (I had them on my Ram). I realize you're looking for a tire that handles the street well to, and both of those tires do that flawlessly. The Duratrac is marketed as a mud terrain, but it's more like an all terrain because it's well mannered and surprisingly quiet on the road. If you're looking at a lot of road use, I'd stick with AT tires rather than MT tires (with the exception of the "MT" Duratrac).

3 → Can't help you there, but FWIW, I bought 5 rims/tires from a 2016 Jeep Wrangler Sahara for $700. I sold the tires off them for $300, so I had a total of $500 into the new set of rims. I then sold my 20" Overland rims/tires for $1000, so I had $500 toward the new tires. I could easily have listed the 20's and the take of tires for higher prices, but I was pricing to sell, which both did quickly (the rims the day of listing, the tires the day after listing). The BFG's cost me $875 (for 5 tires I got a discount), so I'm $375 into a brand new set of rims and tires. Plus I've got 2 tires and a rim to sell (stock spare rim, stock spare tire, and original tire from the 5th Sahara rim). With all that sold I should be pretty close to even on the upgrade. Just something to consider.


Here it is with the 20's it had on when I bought it.


And here it is with 18" Sahara rims. If you go this route, just note 2016 version will have granite pockets, while the '15 and prior will be all silver.

That 18" setup looks really good, have you had any rubbing issues?

I am in the process of buying this '14 JGC Overland. It has 17K miles...I did not notice any dings, scratches, etc, but then again I wasn't looking that hard either. I will do that tomorrow when I pick it up. Here is a picture off the dealers website.

how about yours...miles, condition, pictures?

If that wheel is any indication for all 4, they look great. Mine are off my 2016 Limited and have just over 3,330 miles on them, no dings, dents or scratches (no curbing either). I have the wheels coated in a nano-coating from when I did a large detail on my JGC. I don't have any close-up pics but can post some, here is what I have so far...

Thanks, and I've had no issues at all. I did A LOT of research before pulling the trigger on this. The size I got, 255/70/18, are reportedly the biggest you can fit without rubbing. This is with the QuadraLift in any ride height (even park mode).
After buying them I tested in every height setting. At each height, I asked my wife to turn the wheels to full lock both ways while I watched for any contact. All positions were clear, though it is worth mentioning this is while stationary, and I don't know if every height clears with suspension travel over bumps/holes. I was able to confirm though that there was no contact in any position, including park mode while stationary. I haven't had any rubbing while going over bumps/holes, even while in aero mode, so I don't think there will be any issues while moving either, though I'm sure I haven't "tested" every possible condition/position yet.
Also, the size I chose also allows you to fit a matching tire into the spare tire well, and the floor still closes over it. If you opt for a wider tire, it will not fit in the well with the floor closed over it. With a tire wider than 255 You'll need a similar diameter tire that is narrower than your full time set. This is no big deal, since that's exactly what they did with the stock tires. The spare is narrower than the stock tires. If you want a wider tire, and a matched spare you will have to figure something else out for a spare mount locations (such as a roof rack, tailgate mount, or alter the cargo floor and/or spare well).

Chas, first...your front window tint looks perfectly matched...if it looks that good in real life I'll need to know where you got that!

Secondly, I'd like to think about it some more, but I'd likely be interested in doing the trade if you are....understanding the following things. Barring any unforeseen circumstances, I am picking the JGC up tomorrow afternoon. I am leaving for vacation next week and tentatively planning to drive the Jeep. Also, this is my primary business vehicle, so its fairly likely that there will be roughly 22K miles on the tires by mid September. Given your lesser miles, and given the relative cost difference between the 18s and 20s, are you thinking straight trade or something else? Also, we can move this to a PM, Text or email if you prefer.
