potenza re92
 

are 175/65 14 Bridgestone Potenza RE92 as good as the insight Bridgestone Potenza RE92 or are they are just normal tire. because i found used Bridgestone Potenza RE92 on kijiji and i want to know if they were just normal tire or good lrr tire

RE92 is a popular factory tire (not necessarilly much liked by car owners though including myself).
Subaru, Nissan, and Hyundai use that tire on many of their car models.
I don't know about its rolling resistance, but it performs okay on dry, not great on wet. terrible in winter.

from what ive read, the 165 65 14 insight tires are a very different animal from all the rest of the re 92's

the re 92 is only considered a low rolling resistance tire in the 165 65 14 size, on tirerack Bridgestone*Potenza RE92 then click specs
