tramming has more to do with tread pattern than size.

i used to get traming with 205/50/15 good year GA as well as 225/45/17 and 245/40/17 dunlops.

the current 235/45/17 and 255/40/17 toyo t1-s does not tramline at all.


also it's not just the forces on the tires but the tendency of the tire to follow the groove/lines on the road surface.
