Cool ole Binder. Some nice Alcoa 22.5's would look great on that, but I'm afraid they won't work.

Re: 9r20

One issue with going to a taller tires on the old IH trucks is the truning radius increases and the amount of effort required to steer also increases. I would leave the 9r20's on the front and go 11R20's on the back

Re: 9r20

This would be the forum for these trucks
http://www.oldihc.org/

I haven't work on any IH trucks in about thirty years so my info is a bit spoty.

Re: 9r20

tecky, I moved this for you to Alternate Tinkerings. There's a few guys on the board who fool with IH's and I think you'll get better exposure here.
