say what you want, these cars are not designed in your or mine backyard.
these cars involves heavy investment in R&D and only then they roll out in the market..
if it was this easy by now all chinese cars would have taken over the world auto industry considering its ability to produce for masses.
but only one thing is holding back china that is R&D, they do not spend rats on it rather prefer copying.
so yeah you can take out your frustration here but you can not write off the fact that these cars are result of good amount of time spent on table.
so my advise to all new cultus owners is stick to stock tyre size rather being a overconfident smart arse resulting in irregular behavior of car and parts.
