I installed a set just before I departed for the National Rally in Johnson City TN. I now have just over 4K miles on them. They replaced a set of Pilot GT's. So far I love'em! Yes, they wonder a little on "Rain Groved" pavement and they are a little "Sensitive" when Slabing it from point A to B.
However, they improved the Ridability of my Connie greatly! It's more nimbile and feels lighter when under way. The GT's made her feel like a Tank and a handfull when in the Twisties.
I havent had any issues with "Out of Roundness" to this point and they dont show any signs of wear other then a 1/2" "Chicken Strip". For my money, these are the best set of "Matched" tires for the C-10.
Just my $0.02.
