That's a really cool thing about resistance rollers - just throw your road bike on them and ride, plus plenty of resistance to do intervals, anything you want. They have trainers beat all hollow for everything except standing sprints, and you shouldn't be sprinting indoors anyway, waste of time.
My strong guess is that everyone who uses a trainer checks their tire pressure, at least the rear. Kinda have to to get consistent results.
I think like you said roller user users just jump on and ride. Trainer set up folks check not enough regular items on the bike. BUT a wheel on trainer requires the roller to be pushed against the wheel with a screw type applied pressure. The rollers are using your body weight pressure to apply the contact. I imagine the wear is greater because the force to push the roller into the wheel is probably pretty high? I don't know this just my thoughts.
