Shaking at highway speeds (new tires, balanced, alignment is fine)

[Ukrainian102]

So yesterday I was doing some parking lot snow drifting and I hit pavement spots a few times (not too hard), and I know it's hard on the car.

Anyway. Today I was going on the highway, and at about 55-65 miles an hour I start getting horrible shaking (whole car, not steering wheel). I've done donuts an ass-drags in the snow before, and nothing was ever wrong with my car after.

I just put new tires on (and balanced) a few months ago. My alignment is perfectly fine (doesn't wander off in any direction, even at high speed). I've had my front axles replaced within the past year, so I think the CV joints are pretty new.

I've noticed the right rear wheel is a lot harder to spin than the left rear wheel. Could something be frozen or jammed inside the brake drum? Did I fuck something up major?

Edit: Knocked some ice off the wheel wells, took off the right rear wheel (the one thats hard to spin) and put it back on again. Took it down the highway again and seems to be completely fine now...

thats weird? I know mine used to shake doing 160 km/h no slower and no faster had to be 160 lol. Maybe you've hurt the tires? shifted a belt or something. I do MUCH MUCH worse to my car than what you explain. All summer doing 75 km/h plus sliding around most corners and so on and it hasn't taken anything out yet. I haven't had the chance to wear a set of tires down enough to have problems like that.

Maybe the rear tire was on to tight not that I can see that affecting the breaks :S

Did you check if you have chunks of ice stuck to the inside of your rear wheels?

Yeah thats the first thing I did... check underbody for ice and stuff. But the car was in the garage overnight so it should have thawed anyway.

Guess it's fine now, no idea what it was though.
