I read in the July issue of Road&Track mag.that they had to replace the Goodyear Eagle F1 Super EMT tires at 5800 and 10,200 miles!This was on a Cadillac CTS-V,on long term test drive.R&T says tires cost $568 a pair.I was wondering what the mileage for the Eagle F1 GS-DS tire would be?I read a thread on this tire here,stating it was a alsome high performance tire for the C5.
