There are ways to increase or decrease stagger. Visit your local dirt track! For example: take harbor freight torch, and a tire that is bigger out of two. Take out valve steam and heat the tire from senter out but do not heat the side walls. And it is best done while tire is on axle or freespending hub. So you rotate the tire while heating. You will see tire shrinking in. Stop. Take it off and deep it in bucket with cold water but keep valve steam out of water. Let it cool of put valve steam back in air up. And check. If you want to grow a tire, add extra 5-8 lbs of air and while spending around heat the side walls. Lett cool of on its own. Let some air out and check. Hope that helps.
