Several do it but if you happen to get rain it will be a big problem obviously. I have done 5 drag weeks and I have run into some big rain but never for very long. That being said I run a regular radial TA on the road and don't sweat it if we do get rain. The last thing I want to do is put put for 200 miles at 25mph in the event of a large rain storm.

Don't ask me how I know but if your car has windshield wiper linkage under the dash give it a look while it is working. You wouldn't want it to snag a small wire and cause you to have to rewire stuff in the pouring rain under a gas station awning in nowhere cornville USA.
