You don’t have to get bigger tires, but your Jeep will look goofy.
This is my JL after it got the Mopar lift; before it got 35-inch tires. These are 33.2-inch tires, to boot; 0.5-inch taller than the stock tires on your Rubicon.
After you get bigger tires, you will need to recalibrate the speedometer. You can either have the dealer do it —normally for $100-$150– or buy a $330 Tazer programmer and do it yourself.
You can do a bunch of other wonderful things with a Tazer, like disable ESS, disable weather alerts, etc.
