Rain tires ready for Busch race, just in case

Goodyear brought rain tires to Montreal, cars will also have windshield wipers, defrosters and rear lights, just in case it rains.  NASCAR seems determined not to get the race put off or delayed this time.  Same setup is also said to be the same for the Busch race at Watkins Glen.

We've heard this happen before in the past, but it never rained, so it hasn't been tested out in race conditions and from the weather reports, it doesn't appear they will need them this weekend either, but they are on hand if needed. 

Other series race in the rain, but with the ovals NASCAR drives on it hasn't been deemed safe to attempt rain tires, rain tires are only designated for road courses.  While it may be considered safe for them to race in the rain, as long as it's not a downpour, is it really safe for the over the wall crews?  If it's raining, pit road will be wet, the wall will be wet and there is always the chance of someone slipping and falling.  Then you have the factor of cars coming in on a wet pit road, I would think it ups the danger factor for the over the wall guys and for pit road accidents between cars.

Don't get me wrong, I hate rain delays and hate it when a race gets put off for another day because of the rain, but for the safety of all involved, maybe NASCAR is right in not using rain tires all these years.

Your thoughts?  Are rain tires a good idea, even if it is just for the road courses?
