I’m currently deliberating my next tire size for my 03 Liberty. Currently i got 245/75R16 on MOAB rims, i got OME lift plus two conduit clevis spacer and JBA UCA up front and two isolators in the back, regeared to 4.11, pinch weld pounded over. I’ll be building a custom front bumper so i thought it might be worth upsizing to 265/75R16 Falken Wildpeaks AT4. My concern is how much will it effect gas mileage and overall performance, also could there be any issues in the back with my setup? If anyone has experience with this tire size your input would be greatly appreciated.
