Good luck, and keep us posted.
It is an oft repeated excuse than people hear from dealers who would rather blame tires (and peoples' choices of rim/style) than a 'sub optimal' alignment.

I am of the firm conviction that you take the SAME model tire- everything the same- and mount an 18, 19 and 20, AND ALIGN IT FOR BEST WEAR, the differnce in lifetime will not be dramatic. Within 10-20%. All IMO.

The problem with trying to correlate anecdotes here is that 20" rubber tends to be softer compound- and nobody really know WHAT their alignment specs are. In fact most owners will go through tire set after tire set, and never get the alignment checked!

And, as we can all agree- OP with 2400 miles is seeing abnormal wear no matter what the size and compound
