honda civic vibration at highway speed?
 

The car was bought used with about 94000 miles on it. year 2000. When I accelerate to about 55mph, my civic vibrates like crazy. This vibration goes away if I go over about 65mph. I've talked to several people about it they say different things like i need it realigned, or my suspension needs a look, the bearings may be it, i need new tires, the driveshaft needs replacement, or the tires are flat. Which of those seem to fit better? Anything else I should check out? I live in Minnesota and during the summer this never happened (although i had a minor vibration when idle) but we recently got snow so this problem showed up. Thanks.

Could be alignment or any of the options you listedbut the most common reason your car vibrates and then as you go faster does not vibrate as much is tires. it is either a tire out of alignment or you have a steel band broke in your tire. the best thing to do is to take it to get your tires rotated. they will tell you if you have any tire troubles that would cause it and its pretty cheap to just have them rotated. tell them your problem and ask them if they have any additional ideas. they will probably check your tire ware and anything that has to do with steering and breaking.hope this helps :)

Not to add more possibilities, but it could be a bent wheel too. The tires are the first thing to check though, because as suggested by someone else, it's the quickest, easiest and cheapest thing to eliminate as a problem. The problem with a vibration is that it leads to other problems. All that extra shaking isn't good for the car, so get it checked as soon as you can. Easier said than done this time of year, I know.
