It's called tram lining. Basically following ruts in the roads like a tram car on the tracks.

I wouldn't think it was the tires unless they are super grippy low profile tires. I think it's the rims. When you change the offset, you are changing the overall suspension geometry. Front drivers are very suceptible to such things.

Have you had an alignment? It's always a good idea when changing the wheel size.
