heavier pedaling after tire change (19 to 25)
hello, since I changed the tire on the rear wheel from 19 to 25, I have the feeling that the pedaling is heavier. How do you explain?
Maybe it can be because the old one was worn out and completely smooth so it rolled better?
The rim has a 13mm internal channel, maybe it's not suitable for 25mm tyres?

You could benefit from a tire with a center strip. Something like the Continental Ride Tour. Its a slightly heavier tire but offers great flat protection and a raised center area that provides a faster ride on smooth tarmac...

Maybe the leading side of tire is rubbing the chainstay under load. This can happen more easily on lower-level bikes with stamped dropouts.

What brand and model was the old tire? The new? That alone can make a very large difference. Without knowing that, all we can do here is speculate and offer generalities.

All things being equal, "heavier pedaling", to me, means lower tire pressure, stiffer sidewalls (less flexible, less supple) .
Things are not equal, so the extra mass of the new rear tire is certainly being felt, as well. This will be most felt during acceleration (up or down), such as when pulling away from a stop sign or trying to accelerate going uphill.
If you went from a supple, high quality tire to a lesser quality tire, you notice it.
Finally, if you changed the tube from a light tube to a heavier, puncture resistant tube, that would also be noticeable.
The flip side of that is, if you want to get some of that back, buy a couple of latex tubes. They usually change th eride quality whenever they are used, albeit they require daily pumping and are more flat-prone.

The only thing that would happen in that situation is that it more easily rolls sideways in the corners. You can adjust it by putting more air in the tires, but you don't want too much air either.

the old one was a cheap Btwin rigid tyre. the new one is a soft Michelin Lithion 2 tire.
The tire does not touch the frame and the brakes. The tube is inflated to a very high pressure, feels hard to the touch.
