Help with 22.5 Wheels/Tire size

[JPBrecheisen]

All,

Need help trying to figure out if an 11R22.5 tire will fit with these wheels on a 1960 C60. It currently has 8.25-20 bias ply rubber with the widow maker RH-5 two-piece split rims.

Upgrading to 22.5 steel wheels. The "stock" width is 6.75 which you can only run a 10R22.5 on. The wheel builder says they can make 7.5 or 8.25 widths on request to run the 11R22.5 size tire. I'd like the larger tire as I have a single speed rear end and would like to be able to run at 55-60 without turning the engine near 3000 RPM.

I am afraid the rear dual set up will not clear either the leaf springs and/or they tire/wheel combo will touch each other once the duals are bolted together.

jumpsoffrock bought a set of the aftermarket 28160 wheels and I am tracking the issue with the lug holes.


Thanks for the help.
