After hemming and hawing between another set of Goodyears, the Ecopias, and mulling about bargain basement foreign brands, I decided to go with Starfire RS-C 2.0 tires.
Starfire is a sub-brand of Cooper. The sidewalls say they are made in Mexico. Their mention of low rolling resistance honed me in, but the positive reviews and especially the price is what sealed the deal. I walked out of the tire shop having paid only $305 for a set of four, mounted, taxes and all.
The first surprise is how quiet these tires are. Super quiet! Much more so than the Goodyears they replace, or the Blizzaks I run during the winter.
I have not seen any appreciable hit to range, but this is hard to gauge at the moment, as we are coming out of the longest Michigan winter on record that really did a number on my lifetime eMPG.
Also, while others rate these a bit lower on rain, and especially snow and ice, I'm not worried, as I do run the Blizzaks during the winter. But the rain performance of these tires during a Michigan spring, at least new, is more than adequate, even great.
I'm only a few thousand miles in at the moment, so I will have to come back with a long term followup, but so far, I am seriously impressed with the value of these tires. Would definitely buy them again for my 2013 Volt.
