For sticky roadbike tyres it looks worthwhile on some brands, for ADV tyres many actually cheaper or negligible difference here!
BTW the dollar seems on a downward trend against USA so buying ex USA will be less worthwhile soon. Typically our dollar goes up and down in a 7-8 year cycle, which I found out about when returning from UK OE and wanting to bring my savings home
Had to wait couple years before it was worthwhile.
