Even in the most horrible of rain races, Dirt Stockers won't last for more than about 1-2 hrs. The compound is just too soft. I've had a set for several years, now. Ran them once, and they were majic. I haven't taken good care of them, so they have some bad dry rot. However, they will still do a race or qualifying session.
I've been told by the Appalachian guys that the dirt stockers were going away, but they had some fresh ones at the ARRC. I bought a set of the new style radials, just in case. According to those guys, if it's hard raining, the Dirt Stockers are the way to go. But if it starts to dry, they are done in no time. The new radials are more consistant. Not as good in deep water as the Dirt Stockers, but won't go away when it starts to dry. I'll take better care of them.
Rain tires are like insurance policies...if you have them, they cost a lot to just sit on the trailer. But when you need them they're there ready to go. Or you could take a chance on dry tires and tire bundles.
