This may be a dumb question but I would feel better with input from you guys on this. Due to the danger of inflating split rims and everything I have heard. I am so freaked out about this that even when I am just checking and adding air pressure to take the stears up to around 60 PSI and the rears to 50-55 PSI I am sweating bullets. I have the snap on air chuck and the long hose and the distribution andle with the built in pressure guage so I can stand behind the truck while airing up the tires. When I go around to take the chuck off the stem I can just see the ring taking off my hand at any moment. I have had experienced people tell me that once the ring is set and there is air in the tires and they have been running that it's safe but I'm still not sure.

I should just chill out about this right?
