It's true, wider rims will cause tramlining which forces your car to follow the grooves in the road. Just one of the side effects of bigger/wider wheels. Do a search for it in the tire forums and you'll get all the information you need on this.

I'll say from personal expirience that tremlining depends more on the tire than on the wheel.....Agressive sports tires(ie S03) are known for their crappy tremlining.

I've noticed the same thing with keeping same size tyres and just changing to the new Dunlop SP Sport. They grip anything in sight and tend to pull the car in that direction, I had them balanced and rotated twice before I believed it was just the tyres doing their job on bad road.

tramlining just keeps you more aware and active as a driver is the way I look at it.

but hes not talking about tramlining... right?

You may have a little tramlinin whit 18s and 19s, but the steering don`t really needs to move weird or something.

No the 18s definately create a lot of tramlining even the MV Spokes. I notice it a lot on highways and such where there are a lot of ruts made from constant travel, and especially while coming to stops if I let of the wheel it will go right the left or right.

I think your problem are the tires. What kind/brand do you have? I had 17" wheels with Bridgeton S03's and they were tramlining badly. Then I got 4 18x8.5 Hm2's with Kumho 712s and they were fine.
