Default Question of using wider tires

First of all, sorry for my poor english

I recently put the 04' STi wheels on my 07' 2.5i.
-STi wheels tire size is 225-45-17
-2.5i wheels tire size is 205-55-16

When you drive, if you let go of the steeling wheel, the wheel will snap to one side or the other a little bit, if the surface of the road is not perfectly flat, or bumpy.
After I put the STi wheels on, I find that the steeling wheel is going crazy to left or right if the road is not flat or bumpy.
Is it normal for a wider wheels or do I need to do something

Default Road's fault

Yoshi, it is the roads fault. being that you are in Vancouver, i am guessing by "road not flat" you are talking about two ruts or grooves formed by years of chained and studded snow tires being driven on the road. Basically your wider tire cannot fit into the ruts and every time an edge of the tire moves into the rut you feel the steering wheel snap to the left or right. try sticking to one side of the lane and see if there is a difference.

edit: i feel stupid, just looked at Vancouver's annual snow fall...like 5" at most. i figured it was like denver...jerks wear studded snow tires all winter long, no matter if it is snowing or not.

Studs or chains in Vancouver is tres funny!!


It is the correct answer though... the pulling is your tires "tramlining" along the uneven surface.

So is it:
wider = more pulling?

I'm thinking of putting the same wheels (from and '04 STi) onto my 2.5i. Have you had any rubbing problems? I called tire rack and they say 17"x7.5" 53mm offset will rub the suspension on a 2.5i.

If you have a stock suspension setup, you wont have any rubbing issues with the 2.5i and some STi wheels (even under full load). If you decide to lower the car, then you'll have problems. You'll see that the rear wheels still look a little tucked in with 7 inch wide wheels.

17 by 8 is a different story.
