wondering if someone can help me with some tire issues. It is time to replace my rears, 87 930. I currently have yoko es100 205 55 zr16 front 245 45 zr16 rear. I would like to continue to use my stock Fuchs. is it possible or desirable to run 225 55 16s on the front with this wheel to help with understeer and also could I run 245 50 16 on the rear instead of 245 45 16. the 45 is becoming impossible to obtain from yokohama, while the 50 is widely available. just wondering if anyone sees a problem with rubbing with the taller sidewall. Thanks for your help guys.
