Every vehicle I've had since 1985 has had tinted windows and had reduced heat radiating, especially in south Florida.
Now days with better ceramic tinting are much more reducing heat radiating,
I was gong to ask, about your roof glass as to less heat radiating but you answered before I asked you and I do believe tinting the roof glass would help reduce heat radiating,
Also it is not just the heat but the sun UV bleaching and cracking your interior.
