what does it usually mean if my car vibrates when i'm driving fast?

Answer 1

It means that you are about to reach light speed. In most states you would be far above the speed limit so watch out for speed traps. Also be sure that your tire pressure is adequate because, man, if you have a blow-out at light speed you're gonna roll for hours.

Do me a favor: when you do reach light speed, turn on your headlights and observe what happens. There are people here who constantly ask that question and it would be good to put this issue to rest once and for all.

Thanks.

Answer 2

If it happens only at certain speeds, and always at those speeds, odds are your wheels are not balanced. Most places balance them when they install tires. I would return to the place you bought your tires and ask them to rebalance the wheels. If that doesn't work, go back and have them explain to you why it's still vibrating. You may have a bent or dented wheel that you need to have replaced or repaired...it's usually not expensive to replace stock steel wheels, unless you have an expensive car. If this is the case, ask the shop to move the damaged wheel to the back. That usually cuts down on the vibration a lot, especially on bigger cars.

Alignment will not cause vibration. Vibration can, however, knock your car out of alignment causing it to drift.

Answer 3

Vibration which increases with speed usually indicates a tire that needs balancing. The wheel could've lost a wheel weight or the tire could be wearing unevenly or cupping if the front end is out of alignment or worn. This could also be caused if you don't rotate your tires often enough, if the tire is very low on pressure or if your front wheel bearings have too much free play in them.

Take your car to a reputable tire dealer, have them re-balance your tires and rotate them. Then get them to measure tread depth across the tread to see if the tires are wearing unevenly. Don't let them sell you a set of new tires unless yours are truly shot. Get a second opinion or bring a car-savy friend with you if you need to.

Answer 4

90 % of the tire your tires are out of balance. The rest of the times your tires are damaged, front end components are worn and need replacing, driveshaft weight fell off(Rear wheel drive cars only) and or the alignment is way out of specs. I will go with the tire balancing. You can have the 2 front tires checked 1st for balancing at any repair center that sells tires. They can high speed balance your 2 front tires and then road test the car again on the highways.
good luck........

Answer 5

1 Tires out of balance

2 Bad tires, a common problem with radials they are bad at seperating which causes air between the radial plys and makes the tire equalize. It also means it could blow out at anytime. Check the side of the tires and see if they have small bubbles or uneven wear.

3 Shocks or alignment only after you have checked the tires or replaced them.

4 Bad front end.

Mainly sounds like you need to slow down and check this before you cause a wreck.

Answer 6

I went to a area in my residential community the place there grow to be a exceptionally sturdy hill, and spent a pair of hours basically combating and commencing until eventually I felt mushy doing it.

Answer 7

Your car may need either an alignment, the tires rotated and balanced or both. Neither is terribly expensive, but it sounds like that could be your problem.

Answer 8

Either your tires are out of balance or you have a knot on one or more of your tires. You need to get your car into a garage and have it checked out.

Answer 9

My Cadillac Deville vibrates when I approach 90MPH and my Chrysler Town and Country when I approach 80. Cad. is v8, T and C is V6. I think its because these cars/engines have reached their practical speed capacity or maybe its just to remind you to slow down ;-).
