If you have a door opener adjust it so the door opens further.
Wether you have a opener or not, adjusting the springs may not raise the door enough. The point of the springs be they torsion ( above the door, on the header) or the old style springs along the top rail, is so the door is balanced. Meaning if the door is opened 1/2 way the door will stay where it stopped.
If your spring(s) are the torsion style, and you have never worked on them, I strongly advise NOT adjusting them yourself.
I personally know 2 people who were off work because of injuries from trying this.
I do know the proper way to adjust this type of spring, and have done it a number of times.
I have a 7' garage door, my SOA CJ on 36" tires fits under my door, if I disconnect the opener and push the door up. A 2x4 is used to hold it up far enough. ( between the header and door)
My other CJ with 35" tires and 4" of lift fits thru the door without disconnecting the opener.
