I recently bought a Mavic A 319 rim with ETRO 622 x 19C and Schwalbe Marathon 28" tire with ETRO 32-622. Based on the tire sizing chart found at Sheldown Brown (https://www.sheldonbrown.com/tire-sizing.html) and the recommended tire width by Mavic of 28 to 47 mm, I thought that the 32mm would fit for sure. However, it requires enormous strength to pull the tire onto the rim. Much more than any tire that I have changed in the past. Because of the very tight fit, my tire was pulled down slightly on one side, making it run unevenly. To correct for this I had to pull and push on different parts of the tire to make it fit evenly. Also, something I never needed to do on a bike.
Is this expected, because the 32 are on the low end of the spectrum or did I read the numbers wrong?
