I got my Icons 17" wheels on, running it with 285/70/18 KO2 Load Range C. I'm loving it so far, not as heavy and stiff as the Load E's, and gas mileage is less than 1mpg worse than before. They look and rides really well, this tire size, you can find tonnnnns of them on CL and FB marketplace, these came on the new Rubicons, most Jeep guys just buy the jeep and upgrade to 35's and sell these for next to nothing. The wheel weigh 27.5lbs per my scale, and the tire weigh 51.5lbs per my scale.
They look just about right, not too big not too small on the 100
This is a pic of the least reliable vehicle ever made, and the most reliable vehicle ever made.
I did a test, i filled up at the Wawa near my work, this is on stock Michelin tires, 150lbs cargo, a 100lb full spare from my 305/65/18 setup, a set of sliders, and roof rack with miscellaneous junk on top. Flat road, no hills, no traffic, a smooth ride home on saturday with 20% city driving and 80% freeway. I kept it at 70mph on the hwy, drove 30 total miles.
Result was impressive
Now i mounted the new setup, same gas station, same cargo same route home, same style of driving. Keep in mind the new setup is roughly 6% larger than the stock so you have to add in some more miles to the avg for speedo error. I drove same path home and it registered 28 miles not 30. If my Asian math is correct, after corrected MPG calculated by the diameter difference, i'm getting 19.2 mpg
Overall i'm happy with my switch, this new setup should stuff into the fender and not rub during full compression, can't say the same about the previous setup, it was a tad too big and super heavy 97lbs total. They do look good though, makes the 100 look like a tank
