precut stair stringer question

I tried searching the archives, but didn't find anything, so figured I'd ask here.

I have some precut stringers, and I've noticed that the routered slots for the treads taper from about 1 3/8" in the rear to a 1" bullnose front. Can anyone tell me why it's tapered? And also, how would I go about putting the treads in? I assume they need to be wedged from underneath the tread somehow? Thanks for any info!

I think they're designed to be used with prefab (tapered) treads. I never thought about how to put the trads in, must be from behind.

They're intended for stair wedges, which are driven under the tread to reduce squeaking.

Yes, spread with glue and then driven in.

I figured it was something like that. I'll have to see if they are something that is readily available...thanks. I just wanted to make sure that I was on the right track before I tried to find the stuff I needed.
