I just bought a Santa Fe SE, and I like it, except that I did prefer the smoother ride on the GLS, which has the 16" wheels, and therefore larger sidewalls and superior cushioning. I asked the service dept. at the dealership if I could change the SE's wheels to 16" GLE wheels. He said this was impossible, and gave some explanation that wasn't all that clear over the phone about wheel sensors. The circumference difference is negligible, so I honestly don't understand what the issue could be. Does anyone know why I shouldn't be able to do this? I plan on double-checking with another dealer.
