Drag Radials in the rain?

I say NO if you like the car and yourself.

While they are DOT legal, that doesnt mean you should run them on the street during wet weather.

Tread and sipes exist on a tire for one reason-wet weather traction. This tire was not designed for wet weather so if you are in the rain running 60 mph and hit a puddle-instant hydroplane and loss of control.

If you want drag radials for your street car, I would say either drive ONLY in dry weather or put them on spare wheels you can swap at the track.

This is from BF Goodrich concerning their drag radial:

"On the street: These tires have a reduced tread depth when new and a tread rubber compound optimized for straight-line grip. As such, they will wear out much sooner and offer less wet grip when compared to normal passenger car tires......Reduce speeds in wet conditions and whenever standing water in present."
