Wheel and Tire Recommendations - '33 Hot Rod

[JimLev]

For the IRS I'm using 5x4.5 bolt pattern.
The wheels I purchased for my full fender '33 are:
Front, Torq Thrust II, 17x8, Backspace 5.48", VN8157867 Chrome PVD, Tires are 235/45/17
Rear, Torq Thrust II, 18x10 Backspace 5.75", VN8158165 Chrome PVD, Tires are 295/35/18

These clear the FFR Ford supplied brakes. The hub bore of these wheels are 83mm, the OD of the hub 70.4mm.
Anyone know if there are hub centric rings are available for these wheels or if they really aren't needed?

Update:
NAZ said hub centric rings are not required.
