Has anyone tried taking 800/70R38 off 9530 and put on 9770 as duals? Dealer has a kit to buy new 800's and rims and run as duals. Wondering if we can use the outside tires off our 9530 since it doesnt look like we will be doing any field work with it. Wondering if the rims and 10in spacer will work or if we need to just buy a whole new set?

We have to put axle spacers between final drive and axle to give inside dual clearance between tire and combine. 12 inch spacer works greatest. After that you should be able to run duals from tractor as they are the same bolt pattern. You must put at least 10 inch spacer between duals to keep mud from packing between tires.

We have 20.8R42 duals on this combine now so we already have axle spacers. Just trying to figure out if the dish on the rims and the 10 in spacer will work. And will the final drive be ok with the wheels spread that much?
