Default Heavy steering after changing the tyres

Dear All
i have an Impreza 1.6L it comes with 14" wheels, last week i changed the Wheels to 16" Alloy i bought the correct ET 55 as i got an original Subaru Alloys, i also got the correct tyres 205/50 Kumho
i am feeling heavy steering and the steeringwheel tend to turn left if i move slowly or pass by a pumpy road as if the left front tyre is heaver than the right front.
i adjusted everything in the wheels before i install it the car moves in a perfect straight line when i am driving.
should i adjust something or is that from a bad tyres?

It's normal. Not sure what width tires you had on before. 185 maybe? But now you've got more tire in contact with the road so there's going to me a little more heft. But you also might need an alignment.

I always notice a difference when I go to my winter tires from summer tires. 225 to 205 and vice versa.

Edit: Wrong forum too. Wheels and Tires next time.

Also, steel to aluminum by material is weight reduction, but material from a 14" diameter to a 16" diameter increases your moment of inertia.

I definitely notice the difference between my 205 Blizzaks and my 225 Dunlops as well.

it is perfectly normal. My winter tires are soft and easy to steer while my r-s2's feel really heavy.

I wouldn't worry about it, you will get used to it and like it after a while.

This is exactly what happened to me when I went from stock 16" 205s to 18" 225s. The car developed a pull. Alignment cured that problem. I would just go and get it done. If your steering is off, your toe is probably wrong now and your camber is most like not correct either. Toe would account for sluggish steering. Report back after you get your alignment done and let us know if your problem is gone.
