Ray,
Just a suggestion here sir, If your not sure how to change them (considering its a order picker) I would highly recommended a service call to a professional fork lift company. It would be like someone asking "Hey Ray"" I am not sure how many lug nuts are on your daugthers car,but I am sure it will be just fine with only 2"
Not making fun of you,but someone's life is at risk if not done correctly.
