Object flies when pointing at an angle

I set an obstacle in the game for my tank to drive over but it doesn’t seem to wanna act right. First of all when its at an angle like going up a ramp I can just take off into the air instead of falling to the ground like gravity demands, second of all when the front end makes contact with the ramp the back end doesn’t stay in contact with the ground it stays straight. I’m wondering what i did wrong or didn’t do.

Is it your “tank” a “Rigid Body”?

Yeh its a rigid body.

Well, have a good day…I’m joking…
Post a .blend, maybe?!
