I think you might have to position it carefully. 0.2" isn't a lot of leeway.
I saw a post in another forum - someone was having trouble getting the pullers to grab on. The solution was to cover the center hole.

Hey neobop,
Thank you for your response. I went to the store selling the 2 for $7 but they are way small; lucky if they are 2" round. I ended up buying the real 4.5" ones @ $5.99 each. The fit of these is perfect.
You must have ESP. That is exactly the problem I am having with these. They will not grab on. Any idea on what to cover the center hole with?
You're input is much appreciated.
Thanks.

Actually ... I did a little more snooping around and the originator of this method gives a great pictoral display of his procedure here:
