9r20
 

ive just bought me a 55 truck with 9r20's. i was wondering can i upgrade to 11r22.5's here are the pics of the rims.or more afforadbale 19.5's

Re: 9r20
 

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

Re: 9r20
 

why noit just becaue of the funky bolt pattern?

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
 

how about if i wnet eith 19.5 rims and tires? would that clear the drums and reduce effort to turn and steer?

Re: 9r20

This would be the forum for these trucks

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

Re: 9r20
 

the serial number vary because my 54 has 4 numbers but ive seen some with five . guess it just depends on how many were made before yours .

Re: 9r20
 

Sweet thanks! Dmv does not recognize my 6 digit vin

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.
