I'm running the Cobra trike tire now probably 8K miles, or more, before that it was a Bridgestone BT45. I cannot tell difference in running the two tires, so I will probably return to the BT45 when it's time, considering the price in each of the tires, it's a no brainer. My thing with the Cobra, I've had the very slow leak since I had the tire installed and I can't cure it. I've done it all, reinstall, replaced the valve stem, you name it, that tire has cost me, so I'm not doing that again. I have not read of that happening to any other Cobra tire, so maybe I am just the unlucky one. Not knocking the tire, just my experience, many love the tire and that's all good.
