Tire size

I am interested in an Ecodiesel Overland. I drive on the road a lot for my job and have to go regardless of the weather. The Overland comes with 20" tires but if I choose the off-road package for the Quadradrive and skid plates it also adds 18" tires. So what might you tell me about on road manners and driveability or fuel economy regarding the difference between the two sizes? Because I think I could just choose the Quadradrive by itself if I want the 20's.

Also, I'm having a hard time finding pictures of each to compare the looks but think I may like the looks of the 20's better. Comments?

Re: Tire size

The difference between them is on the wheels relative to diameter. The tires, themselves have the same ~30.6" diameter for the OEM sizes.

Some folks feel that the 18" wheel setup is "more comfortable" and for off-road applications it does give you a little more sidewall. Others prefer the ride of the 20" wheel combinations. It's very subjective. I'm perfectly happy with the 20" wheels, quite frankly, both for looks and ride.

Not hard to find pics at all. ImageUploadedByJeepGarage1454072616.604425.jpgImageUploadedByJeepGarage1454072628.047066.jpg
You're not going to notice much in driving impressions. The 18s will obviously be a tad more cushy due to larger sidewall but have sloppier road feel being its not as friendly of a highway tire. The 18s will probably get 0.01MPG better but since the 18s will have a slightly more aggressive tire for off-roading you're definitely not going to gain any MPG over the road tire that comes on the 20. That's all. Sounds like you're overthinking it.

Yeah, sorry I meant wheels.
