LOL, Twerking is bending over and shaking your rear. Was it bouncing up and down or swaying side to side?
I replaced my tires rated for 65lb max air pressure with GY Endurance rated at 80lb max. At 80lbs my rear would be bouncing up and down. I lowered them to 65lbs and now back to normal. So far I love these tires.
I believe she was working off of a load/pressure formula to calculate your proper pressure. Can you share the formula with us? There is a table to acquire this information but the formula would be good to have.
