I'm not a car guy at all, can you put 'taller tire, higher aspect ratio' into layman's terms? I have the 19" tires, does taller tire mean with more sidewall? I can't even guess what a higher aspect ratio might mean. What is an example of such a tire? Is there one that folks have used that have reported is softens the ride a little bit?
So the idea is to get more sidewall to better absorb the road imperfections, smooth out the ride a little.
To a small degree, tire pressure can also be adjusted to suit. But this only provides a very minor benefit. BTW, low AND higher should be tried.
The Model YLR standard suspension uses a 28" diameter tire on a 19" wheel. Size 255/45/19 is standard.
245=width, 45=aspect ratio (width to sidewall height), 19=wheel size.
It can accommodate a tire up to 29" in diameter (tall). That's a realworld max, although some might say a 29.5" would fit.
The determining factor for max tire diameter is the knuckle on the upper wishbone. There's close to 3/4" clearance above the tread of a 255/45 tire.
A 1 one inch added tire diameter adds 1/2 inch (above and below the tire equator) and it clears. That distance never changes regardless of wheel movement.
It gets tricky when considering tire WIDTH. This is really only an issue on the front, where the tires are turned L/R, and clearance needs to be determined.
You can eyeball this with the MY. Since the car rides so high, there's a lot of room.
Sitting in the car and turning the steering wheel lock-lock will show how much space is available.
