Latitude Tour HP is the best replacement for Diamaris. They are good on wet or dry and decent on snow too. So basically you get a summer tires that is also good for rain and winter months too. I replaced mine after the Diamaris wore out. Dont ever buy General Exclaim Grabber UHP. Those sucks. The threads are too aggressive that makes noise and will develope cupping.
