I installed the kumho ecsta spt on the focus today. First reaction is they do not handle nearly as good as the continentals contisports. You can feel the sidewall flexing on them in the corners. Like the feeling that a sway bar was disconnected. So i bumped up the psi to 45 pounds just too see and they still flex a good amount. They ride nice but not the performance i was expecting from this tire.
Although tire rack has excellent service. Ordered the tires and 1 rim and they showed up at work the next day.

Thanks for your order and supporting Focaljet! I am surprised by your comments on the Kumho's as the 712's have always rated better than the Conti's and when I drove the Escta Sports on the track, I thought they handled better than the 712's. Keep in mind that new tires have mold release on the compound and have full tread depth, the combination of the two can make the tire a little slower to respond until they are broken in - see more below. Please keep us posted as you get a few miles on the tire.

Breaking In Your Tires

Tires are comprised of many layers of rubber, steel and fabric. Due to these different components, your new tires require a "break-in" period to ensure that they deliver their normal ride quality and maximum performance. As tires are cured, a "release lubricant" is applied to prevent them from sticking in their mold. Some of the lubricant stays on the surface of your tires, reducing traction until it is worn away. Five hundred miles of easy acceleration, cornering and braking will allow the mold release lubricant to wear off, allowing the other tire components to begin working together. It is also important to note that your old tires probably had very little tread depth remaining when you felt it was time to replace them. As any autocrosser or racer who has tread rubber shaved off of his tires will tell you "low tread depth tires respond quicker." Don't be surprised if your new tires are a little slower to respond (even if you use the exact same tire as before). Their new, full depth brings with it a little more tread squirm until they wear down.

Thanks, that would explain why they are not handling as good as i thought they were. My continentals where past the wear bars. I have a 900 miles trip this weekend so i will update on how they handle after i get more miles on them. So far they only have about 60 miles.
