proper weird problem at the moment . heres a pic of my golf when i bought it . it had 205/50/15's on it



2 weeks ago i bought a set of wheels off ebay and put them on . the tyres are 205/40/17 . car now looks like this and i love it



now the car steering is lighter . went to the local tyre place and he said thats normal on a lot of cars ??

the car now slides in corners as if your going to fast into the corner and even though your turning the wheel it still goes straight and then turns if you know what i mean ? its like when its wet and you go round a roundabout and if you give it well a car will pull out further even when steering in course the weight of the car is pushing it out and the tyres aint gripping enough till you let the power off ?? if you know what i mean . its a strange one to discribe . it aint that bad in the dry but still handles like its on thin 14 inchs steels ?? im trying as best as i can to decribe what it does ???

it drove fine when i had the standards on it now its poo. i was thinking of selling it anyway when i got new wheels for it cos another car has come up ive wanted for a while but i want to sort this out first really .

the tracking is fine . the lower arms are fine . the steering rack is perfect . so now im thinking is it the tyres ??

3 tyres are cheap make and one is a Avon .

now the avon is a square edge tyre if you know what i mean . the wall is straight to the edge and and the other 3 are round edge , the dip in from the wall to the tread ?

now my question is has anyone else had this problem

are the tyres reall that shite that they would cause this sliding ?? ive always had cheap tyres but never had this problem

some on said get the camber checked but the local place says if it does a 4 wheel alignment and does the camber that it will only be able to put it to the factory settings . and cos the car has bigger wheels and lowering springs it would be wrong anyway ?

ive been told to lower it more and it will help ??

im going outside in a min and will take a pic of the tyre make and shapes .

what do you lot think ??
