wrong tyres for low psi and narrow rims... et's are that way ---------> or not... NT05r's although a drag radial are a proper working street tyre, so you use normal psi on normal width rims, and you can still go around corners and not crash too I had them on a set of lenso D1R's that were 17x9 and they were as narrow as you would go it'd be pushing it fitting them to a 17x8
