Counterbalanced tire profile generating machine

A tire grinding machine, comprising:

• a frame having a plurality of vertically extending posts;
• a chuck assembly associated with said frame, said chuck assembly adapted to receive, and rotate a tire;
• a grinding assembly associated with said frame, said grinding assembly movable with respect to said frame and having at least one grinding element adapted to contact and remove material from the tire when rotated by said chuck assembly;
• and
• a block assembly interposed between said frame and said grinding assembly, said block assembly allowing pivotable movement of said grinding assembly with respect to said frame in a first condition and maintaining a fixed position of said grinding assembly with respect to said frame in a second condition.

A calibration adapter used with a tire grinding machine, comprising:

• a frame having a plurality of vertically extending posts;
• a chuck assembly associated with said frame, said chuck assembly adapted to receive and rotate a tire;
• a grinding assembly associated with said frame, said grinding assembly movable with respect to said frame and having at least one grinding element adapted to contact and remove material from the tire when rotated by said chuck assembly;
• and
• an adapter receivable in said chuck assembly, said adapter having a known position with respect to said chuck assembly so as to allow positional adjustment of said at least one grinding element to said known position for use as a reference point when removing material from the tire.

A grinding element level adjuster used with a tire grinding machine, comprising:

• a frame having a plurality of vertically extending posts;
• a chuck assembly associated with said frame, said chuck assembly adapted to receive and rotate a tire;
• a grinding assembly associated with said frame, said grinding assembly movable with respect to said frame and having at least one grinding element adapted to contact and remove material from the tire when rotated by said chuck assembly;
• and
• a level adjuster coupled to said grinding assembly, said level adjuster selectively loosened and tightened to position said at least one grinding element in a level plane which is substantially parallel to a rotational plane of the tire received in said chucking assembly.
