We do not sell passenger vehicle tires, only special trailer (ST type) and some light truck (LT type) tires, but I can still address your question.

Some vehicles will be offered with several tire size options from the factory. We show that a 2017 Hyundai Santa Fe can be equipped with either 235/55-19 or 235/60-18 size tires. If your Santa Fe Sport has 17-inch rims these may have been installed by the dealership.

It is important to have enough clearance around the tires so you can make turns without the tire contacting any parts of the vehicle and also for the normal up-and-down motion of the car's suspension. Auto makers are the ones that get to decide what tire sizes are safe to use with their vehicles and I recommend consulting with your local dealership.

Your current 235/65R17 tires have a width of 235mm (or 9-1/4-inches) and an overall diameter of 29-inches. The two stock tire sizes noted above have the same width and their diameters are only very slightly different, both just over 29-inches.
