The front tire needs to lead the rear to pull the tractor for steerability. If reversed, the rears will push the front around and make steering very difficult. Ratio's I have seen are 4% lead on the front, meaning you would see slip marks in soft soil, where the front tread met the soil, and at the front side of the tire tread, and none on the rears. Don't ask me to calculate that for you.
If you see the slip marks on the rear of the front tread, the rears are pushing and you are on the wrong side of the equation.....my 2c.

That new tire is WAY bigger than the old one. Something is sure amiss.

thanks, that’s what I thought as well that they would rotate slower … but I got them in for a few days now and everything seem fine and no skid marks behind the threads …. they are not that much bigger once on the rim

The old and new will rotate at the same speed as they did when in 4wd, a taller tire will cover more distance per revolution. If the ratio is too far off the fronts will be trying to dig and push dirt back toward the rears, and the rears can be pulled and skid a bit if the fronts have more traction then the rears.
Also depending on the 4wd engagement if mechanical you may feel a bit of gear "grinding" when trying to engage and can have difficulty disengaging.
