Change of tyre pressure if using 255/50/19 107Y due to higher load rating

[MattM24]

You could try out first, to lower the pressure with use of my list. Mayby that is already enaugh for better comfort.

And mind that wider tyre needs wider rimm. I made rimmwidth calculator, after contact with Vredestein, and uses ratio's from desighners guide of ETRTO.
Also aspect ratio is important in that ( the hight/width division, your /50 in the sizes).
AR /50 has less leeway from measure rimm then fi /80.

255/50R19 is for a 7”-9” wide wheel. The Appolo/Gemini is wheels are 9.5” wide.
Not sure if that matters to you.
