check your tires for broken belts or if see if some of your lead weights are missing.if belts in tires or if they are out of ballance it will cause vibration at 30mph or higher
being overly worn, overly loaded, over-inflated, OR, surprisingly, underinflated (they get very hot if they do not have much air)

Yes, it can but cupping can also have other causes. Over inflated tires can tend to bouce more, especially when combined with weak/worn shocks or struts. When tires bounce cupping can occur when the tires strike the road. Cupping can also be caused by the tire/wheel assembly being out of balance (which can also cause the tires to bounce). Cupping is just one of several types unusual wear on tires.
tires bounce either because the shock absorbers are trashed or you have the tires over inflated
it will change a little from tread height but typically no even low or over inflated tires can change align angles but if it does not pull to one side or cause irregular tire wear who cares.
The most common result is uneven wear of the tires and tread. Over inflation will cause more wear in the center of the tire while under inflation will cause the outside tread to wear faster. Depending on how much it is under inflated, it could "eat" into your sidewalls if it is really low. Tire inflation also alters your driving performance, handling, and along with increasing gas mileage. Under inflation affects gas mileage because of drag (meaning slow it down) which will make the engine work harder to maintain speed. Try riding a bike with flat tires to see what I mean... haha. The performance and handling is degraded because and under inflated tire will "lean" and roll over itself in turns and increase the sway factor (which may cause you to slide).- Under inflated tires cause your engine to work harder; which means you increase the possibility of your engine blowing out sooner than it's supposed to.- Tires that are under inflated have a huge impact on steering & handling of your vehicle.- If your tires just so happen to squeal when you're turning a corner, that might mean that your tires have low pressure.- Even if your Used Tire is low in pressure, you wouldn't be able to tell; which is why it's important to monitor your tire pressure frequently.- Under inflated tires happens to be the leading cause of tire failure; it lead to tire stress, irregular tread wear, & even causes you to have less control if you regrettably get into an accident.- I think that the most important thing is that when you have tires that are under inflated, you waste more gas.The tire will wear on the outside edge of the tire. Vehicle will also handle poorly and get less mpg.
Have your tires rotated and balanced every 5000 miles. Check air pressures regularly so exterior or interior wear does not occur depending on if the tires are over inflated or under inflated. Manufacture recommended tire pressures can be found within the door jam or in the owners manual.
The humming noise is dependant on the road surface/ tire tread and tire wear. If the tires are scalloped or feathered they will hum. Vibration may be a problem in your suspension or the balancing of one or more of your tires. You can run your hand over the tread (front to back and back to front) if it is wavy or the tread feels jagged/ sharper in 1 direction, you need suspension work and/or an alignment.
AH, YESSS!! THE SHAKING CAR ! TIRES-TIRES-TIRES, MY FRIEND. THOSE ARE USUALLY THE FIRST CULPRITS. YOU MAY HAVE JUST BROKEN OR SLIPPED A STEEL BELT, OR KNOCKED THE BALANCE OR ALIGNMENT OFF, OR OVER-INFLATED A WORN TIRE. SEE YOUR MECHANIC... YOU MAY BE SURPRISED! GOOD LUCK!...BB
Excessive vibration at high speeds on a Ford E-350 despite road force balancing of tires could be caused by issues such as wheel alignment problems, worn suspension components, or a problem with the driveshaft. It is recommended to have a qualified mechanic inspect the vehicle to diagnose and address the root cause of the vibration.
