Hi all. I'm considering the possibility to switch from the 16" wheel and 195/55 tyres to 15" wheel and 185/65, but I can't find any information if the 15" wheel is compatible with the rear disk brake. I assume that the diameter of the disk+caliper is bigger than the drum, so perhaps the 15" wheel will interfere with the brake. Maybe someone here has some information about? Thank you all. PS: sry for my bad english, it's not my mothertongue
All I can say is that most U.S. spec Prius had 15" wheels as standard, but I think U.S. spec cars (gen 2) had rear drum brakes, while the gen 3 cars all had 4 wheel disc brakes and most were equipped with 15" wheels. Hope this helps....
