Tubes are like $4.

Get a couple.

Now not snarky I am.

I like non-threaded valve stems because the pump chuck comes off easier than the ones with the threads.

Threaded stems are good if you have short stems on medium deep rims and need the nut to help you get the chuck on the valve stem.

But I've broken that nut on threaded valve stems trying to wiggle it off.

I just buy longish (48mm currently) stems that are non threaded on my fairly shallow rims.
