I don't think that's neccessarily a disagreement? Both things can be true - if you mostly drive on roads with fast corners, the heavier car will wear out its tyres faster. If you drive on roads with lots of start/stop traffic but not many "at speed" corners then the one that consistently accelerates harder will wear out its tyres quicker.
Yes, it depends on how you drive and where, however I would note the above: 50kmh is typical of city driving and 50m isn't exactly a tight radius. 77kmh is actually quite fast, and 0.39g is actually quite high acceleration (this is flooring it in chill mode in a Tesla model y). I am trying to say that the driving circumstances where the linear forces are more important than the horizontal forces are fewer in number.
