car shakes from 70-85 mph

after about 85 mph the shaking stops, i ithink i just need to balance my rotors. and i should be fine but maybe im worng ?

Is it when braking or just coasting?

Another way to avoid it would be to not do 85...

tires out of balance?? bent rim.... anything like that

check for lumps in your tire to. If your alignment is off it will casue ware on the tires and casue a bubble. check that.

steering wheel shakes when braking, car shakes when accelerating, or coasting inbetween those speeds,

im gonna get the rotors turned when i get off my ass and take out my rotors ....

my tires are wearing down i know that much, who will balance my rims and tires?

any tire shop
