The sizes above are not substitutes. They are just other sizes for the same rim that we have in stock. Switching sizes depends on your car's actual rim width, load index, and wheel-well clearance, which this website can't check. To switch sizes, send a photo of your current tire's sidewall and your car model to LINE @subphaisal and our technicians will help.
