LOST 4-5 MPG WITH NEW COOPERS CS4 TOURING

by GINNY
(LAS VEGAS, NV)

I NEEDED TIRES SO I TRIED COOPERS CS4 TOURING. FROM THE DAY THAT THEY WERE INSTALLED THE MPG WENT DOWN ABOUT 5 MPG. GOOD TIRE SO FAR, BUT NOT SO GOOD TRADE-OFF.

HAS ANYONE HAD THIS EXPERIENCE, OR DOES ANYONE KNOW FOR SURE WHY THIS HAPPENED? THANKS.
