Another wheel question

[lutronjim]

I am interested in new wheels and tires for my 70 C10 SS stock - no lifts or lowering.

I like slots and am looking at American Racing VNA697983 see
https://www.summitracing.com/ga/part...7983/overview/

These are 17x9 with 6 x 5.5 bolt pattern 4.530"backspace.
I am looking at a Michelin 265/70R17 defender tires.

I figure that the 4.5 backspacing put the mounting flange in the center of the wheel. That would put the outside of the wheel 4.5 inches from the hub.

The tire should be 10.4 in wide. This would put the edge of the tire .7 in out from the rim.

Then the widest part of the tire would extend 5.2" past the hub.

I could cut a couple of 5.2" pices of wood and use a yard stick to see if they would stick out beyond the finders. Don't want to sling mud or whatever.

Does this seem reasonable or am I missing something?
I have tried searches but I keep getting into lowered trucks.
