thanks for the input i am running ....the wheels are 19x8.5 et45 and the tyres are falken fk452 215/35zr19
not sure how much diff that is to standard 17 monzas(still for sale plug plug)
my driving is not any different with the exception i,m looking out for potholes and i take corners way steadier due to the flare on the rim with no tyre protection.
also my esp light came on twice but i am very numptynewbie and not sure what i should have done at that stage- does that make the computer calculate differently?
i dont think they are that much heavier to be honest,but thats in laymans terms whist changing them over?!!
hope thats enough new info to find an answer?
thanks again
