I have driven my Prius with these tires for 84,000 miles. The tires were long wearing, but they wore the edges off well before the center section, even with them being inflated to 42 psi front and 40 psi rear. As the miles added up on the tires they became more and more rough riding and any bump in the road while braking would trigger the low traction warning indicator. The tires did not have exceptionally low rolling resistance, but were average. With 84000 miles on them the tire edges were worn past the wear bars, while the center section had would have worn for 10000 more miles. Over all I was disappointed with the tires.
