Rollers are tough on tires.
I think the whole resistance thing is way overrated. Do weights - turn legs. Miles/time in legs does matter.
1X week get that HR way up. Other than that, working hard pedaling does not seem to do much.
Free valuable information.
I have a set of resistance rollers with ~4" ABS drums. I've worn a lot of the ABS down over the ~20,000 miles I have on them, but never noticed any tire wear, ever. Since it's just my regular road bike on there, I wear the tires down some in summer, but don't notice it in winter because I put more miles on the rollers than the road. I suppose it's possible that aluminum rollers wear tires down more quickly, but I doubt it. My watts are only half that of a pro, so maybe that explains it.
