Why do NASCAR trucks make 2 pit stops fuel and then tires? Why don't other series do this?

May be...

Stupid new rule and more dangerous as the pits are more dangerous than the actual track is.

It's a new rule being tried in the truck series this year. It's supposed to save money by reducing pit crew members. To me all I've seen it do is make cautions last longer so guys can pit twice. Which means we get to see more lovely commercials.

I think it is a stupid move.

to save $ and only have a small number of people over the wall on a pit stop. it seems dumb because the more you go down pit road the more likely there is for an altercation (problem) I guess the other series are smart not to do that stupid rule.

It's suppose to save money. Having less crew members over the wall saves money.

They use this in the Truck series for "testing purposes"

Cause NASCAR is stupid and thinks doing that is good and will save money since less people can go over the wall during the pit stop meaning they hire less people.

It's just really stupid and I hope they dump it after the season is over if they don't do it before the season is over.

They started this because it is supposed to save the teams money because they don't have to have as many crew members over the wall. I'm not sure why other series don't do this. They probably will in the future if the rule does save money.nba regular season start
