Honda Accord EX 4 Door here. Lately I feel the passenger's side is lower than the driver's side when driving or standing still. Tire pressure looks fine on all 4 tires. What else could it be?

 

Take a reading

 

32 to 33 psi on all 4 tires.

 

measure the gap between the tire to the fender and see if there is a difference.

 

could be dying/dead suspension bits and pieces

 

Also check the road angle. Roads usually "lean" to the right to allow
water to run off to the sides so it doesn't accumulate on the driving
area. I have a '90 Accord and was seeing the same thing until I measured
the fender to tire on each side, and rear. Mine was fine. A friend of
mine had me sit in his truck while he drove it a short ways down the
road, and his truck looked lower on the passenger side that the driver
side. Pulled a soccer ball out of the back, and we watched it roll to
the side of the road. Maybe you're having the same optical illusion
I was, who knows.
