stock rubicon tire size

[jerseymike]

just swapped my sport s wheels/tires for Mopar wheels with 285/70/17 BFG TA KO2 rubicon tires.

setting tire size with Jscan and debating what size to go with. the tires spec at 32.8" but measure 32.125"

my stock tires spec at 31.3" and scan read 30.63” as stock in the system


options are 32.0, 32.25, 32.5, or 32.75 that I am between. I saw on a video with Tazer that stock rubicon was set at 32.75 which I thought was high, although that is close to spec for the BFG TA KO2.

has anyone with a rubicon checked their stock setting with jscan?

Mine measured about 32" (305/65/17) and after trial and error using a smart phone speedo app...........I ended up setting at 31.75 to get the speedo within 1 mph of my phone app. I tried 32" and the speedo was still off 2-3 mph.

Mine measure right at 32" .

I switched mine to 32.00, seems about right (speedo reads about 1% fast which I think is about what stock is supposed to be)
