I just switched from my Hakka R 175/70/13 winter tires at 55psi to my Bridgestone Potenza RE92 165-65-14 at 60psi and my mileage jumped 7-8 mpg. It felt like changing from somewhat heavy street shoes to a pair of light slippers with a lighter steering feel, increased FAS rolling distances, and reduced power levels needed to maintain speed. The Hakkas were new when I put them on this fall, the Potenzas were first installed in July and had about 5000 miles on them when they were removed this fall.
