rumbling at high speeds

when im on the highway going at least 60+ my car rumbles and i get a nice-but-annoying massage. why is this?

if its your steering wheel constantly shaking you need an alignment. Fixed my prob cause mine would shake when breaking or going 60+

its your tires, get them balanced. or in the worst case scenario you might have bent rims!
that sucks too cause if your car drives shaky then it eats up your suspension, I spent 30 on tire balancing then 380 on fixing bent rims and now I gotta spend close to 500 cause those 6 months of rattling around killed my suspenmsion

damn that sucks. Yea its either alignment or balance most likely has to be them becuause soon as i got a balance and front end alignment it was fine.

ya its not really the steering wheel shaking, it more of the whole car massaging me while im on the highway
