Well Nitto seems to think highly of them. On their super accurate bar graph of dry performance, both the invo and motivo get 4/5 but they rate the invo as having "AA" traction while the motivo has only "A" traction. A 60,000 mile tread warranty is very impressive if they perform well though.
Edit: Realized that's the UTQG traction rating which upon further investigation is found using the tire's straight line wet coefficient of traction as the tire skids across wet asphalt and wet concrete test surfaces.

So it's not really dry performance I guess.
