Re: Replacing 20" rims with 18" on 2011 Overland

My Limited came with 20" wheels and I wanted 18". The dealer swapped wheels with an Overland that was on the lot. The Overland had originally come with 20", and they were previously swapped out for another buyer whose Jeep came with 18" and wanted 20". So the Overland was restored to the original 20", and both the other buyer and I got the wheels we wanted. The dealer recalibrated the speedometer and nothing else was required.

Re: Replacing 20" rims with 18" on 2011 Overland

If you use the OEM size tires on those wheels, both the 18s and 20s will have the same diameter and do not require speedo calibration. I have a set of both wheel sizes and there are no swapping issues.

All WK2 tire pressure sensors are identical regardless of trim level (and the same as those used on some other chrysler products). There are some feature differences between the modules that detect the sensors, however, but the wheel senors will work on all WK2s.

I went from the OEM 20's to the OEM 18's with Yokohama Geolander AT/S and as Cold Case mentioned, the diameter was exactly the same so no recal was necessary. No TPMS issues either.

How do you find the ride of the 20" compared to the 18" on road? I read in one review that roadholding and comfort are noticeably improved running the 18" over the 20"

That depends more on the tire. I have to disagree if we are talking same brand/model tire. 20s will always provide noticeable better road holding, comfort not that much a difference. If you like riding on marshmallows, I think 18s are better for that.

I have OEM 20s and Blizzack 18s. The 20s have superior wet/dry traction and road feel... on ice or hard pack its opposite . They both ride about the same, although the 18s may be a bit stiffer and are certainly noisy.


To be fair, the blizzacks are driven at lower temperatures which may make theirsidewalls stiffer.
