Nonsense
how is it nonsense? im pretty sure a rim has a related/recommended tyre size which will fit safely, and then there will be a limit either smaller and larger becoming more and more stretched or hanging over the rim, where to a point they become unsafe or less safe?
not 100% true as the oems are 8's all round its just not optimal
My oem wheels are 8.0 and 8.5.
my nismo 19's are 8.5 and 9.5
