Can you bring modified cars thru ex oversized wheels fender flares etc etc or is it standard size tracks to go on?

I've got 285 70 R17 tires on an '18 F150 and have no problem

The track for the tires is calibrated for standard passenger-size, with no extra outside space for additional tires. The sign at the entrance to the automatic wash bay disclaims responsibility for any after-market modifications; on one occasion the staff suggested I remove the stock antenna for the radio.
