guys i need you help and opinion on this. my friend is working on yokohama tire factory and he's selling me 4 brand new yokohama parada 215/40/17 for $240 on the 4 pieces. according to him these are the only available series for 215/17 as of now. question, are they harsh on a lowered 7g? i have tried 45 series and its ok for me. has anybody tried? or use the same tire profile? TIA
