I recently took a trip on the highway and once the car got up to about 65mph it started shaking then after 70ish it stopped..Is this my tired or something else???

That happend to me...turned out my tires were not balanced. If it happends when you stop to, it could also be your rotors...spend 30 bucks and have you tires balanced. if that doens;t work then you might have a rotor problem.

Sounds like you are hitting a resonant frequency in that speed range. As stated, it is most likely a balance issue. Your tires are probably the culprit. This can be caused by losing a balancing weight or a broken belt. The rotors are probably less likely since you should feel some indication while breaking, but not impossible.

Make sure the tire pressure is good and see if you can get the tired balanced where you got them. I know I can go back to discount tire and have them reblance the tire three times a year for the life of the tires or something like that. Also check the alignment, just nice to have done while your at it.
