My X5 jumps up/down


New Member
My X5 jumps up/down when the air pressure in the tires is little low then when I add more air it drives normally. Is that normal behavior? For instance the rear tires 39 psi and the front tires 35 psi and if the rear tires come down to 37 or 36 and/or the front tires come down to 32 or 33 and sometimes 34, the car becomes unstable on the road, not fun to drive at all, like if I was driving in a rough field bush. Once all tires front 35/36 psi and back 39/40 psi then I can enjoy the drive. So not sure if this is a normal behavior or something else is wrong. Please advise if you ever had this issue. Thanks all !
