Just drove 20 hours. whole way vibrating/shaky car..steering wheel and evrything. Got alignment few weeks ago,maybe should have tires balanced? In past these kind of symptoms while drivin on highway was my tires bein balanced,but they just were before i got my alignment,my most 2 new tires are in front. back 2 tires are old and same brand. the 2 front ones are both new,but different brands..

 

one word "balancing".

 

If you were doing donuts in the snow I'd say get a car wash cuz snow in the rims will make the car shake

 

i had the same problem with my wifes civic. I got 2 new tires after 2 were stolen. I put the new ones on the front since civic are fwd. they shook all the time. got the tires balanced and it didnt make any difference. switched them to the rear and it went away. i dont know the reason at all. only thing i can think is the different tread pattern. but i didnt think it would cause the problems

 

My car shook too, but since my suspension was very old and rusted, I decide to replace struts, tie rods and a couple of other things. Shaking went away, the car is now much more stable, turns better and doesn't bounce up and down after a bump.

 

Same problem, but ez fixed. Checked the tie rods and it was having lots of play forgot if it was the outer or inners. Replaced it and cha ching! never shook or wobble on the freeway again.
