Instructions said you don't need to remove the tires, but it is 10 times easier if you do. Also, the instructions only provide for no fender flares or factory fender flares. My 2014 F150 has 3rd party fender flares that made the installation much more difficult than I anticipated. Took total of 4.5 hours, removal of the flares and the tires. Way too much time and effort for the benefit derived from the liners.
