Yeah, you have to opt to have the 4.10's in the Rubicon's now.
Those tires would make a fairly noticeable impact on MPG's. Also, your Jeep is heavier now. Was every other variable the same? Power windows, locks, hardtop, softtop, etc? If so, the JKUR adds probably a couple hundred pounds on a Sport. That combined with the tires and the fact that Rubicon's tend to sit a tad higher than a Sport, would be enough to drop the MPG's a little.
