I recently purchased my jk. Slowly changing things to the way I would like them. I currently have a 3 inch lift, and I'm running on 20 inch black rhino rims with the tires at 30. I had planned to eventually change rim size as I'm unable to air down without fear of rolling off the bead. Took the vehicle in recently as it was making a strange noise when driving. (Was told jeeps make noise... 3 mechanics later, yeah its the bearings.) Was told by a mechanic the rims are too heavy, it's putting stress on the bearings, and this will just keep happening. As this is my first jk I have no idea what I should be looking for when buying rims. Any and all information or suggestions would be greatly appreciated.
