Yes. However, the Yaris is especially sensitive to proper fitment, and just a couple of mm's can make the difference between an acceptable application and one with rubbing issues.
Add to that acceptable manufacturing tolerances; one car is different from the next, and even the same car can vary from one side to the other. Plus, wheel specs are not always entirely accurate, and a 205mm tyre, for example, varies in width among models and brands.
Nevertheless, recommended fitments generally work very well on most cars with stock suspension, and because of this forum and member feedback, we've learned what works and doesn't work so well.
