The other day I was going to my brothers place and it’s about 45 min drive down the highway, the car drove really rough, like one of the wheels was off balance, it was shacking the whole way down the highway. But when I went home about 5 hours later the car drove perfectly smooth down the highway. The car is a 97 Formula, the suspension is stock, it has 18” ROH RT’s with 295’s in the rear and 275’s in the front, I’ve noticed the shaky ride before but always thought it was just the road because the next time I’d drive the car it would be fine. So could I have a problem with my suspension?

Thanks
