Hello

unfortunately I can't seem to get michelin super sport in 255/35/18 here in europe....specifically Greece for rear.

I can only get the following... Super sports

225 40 R 18 88 Y * F B 71dB
235 45 R 18 94 ZR(Y) F A 71dB
245 45 R 18 100 ZR(Y) XL E A 71dB
245 40 R 18 97 ZR(Y) XL E A 71dB
245 35 R 18 92 Y XL | * E B 71dB
265 45 R 18 101 ZR(Y) E A 71dB
265 40 R 18 101 ZR(Y) XL E A 71dB

Can you please help me pick the best fit for my 2007 e92 for rear to match the 225/40/18 for the front?

Please elaborate what I'll gain lose by going up ro down.

Much appreciated.
