genuinely no problem so far in rain, flood, ice etc. been very good. before them i had a mix of re040's and nankangs, bothe were absolutely awful when it got cold or wet, really ruined the car.
EDIT: but next time i will be buying MPS2's
I tried re050's also and didnt get on with them, although later found out i had been supplied runflats which would account for the odd feel, hence me not really mentioning them as its not a fair review.
