Maximum backspacing on 96 GMC 1/2 ton 2WD?

[Cruiser]

Does anyone know what the maximum wheel backspacing is (front and rear) for a 1/2 ton 2WD 96 GMC/Chevy truck at stock height?

I have a set of 17x7.5" wheels and I am going to have to get adapters for them to work, and also allow for some backspacing difference, but I cannot find specs ANYWHERE...

I'm going to be running 275/60-17 Goodyear Eagle GT II tires on some Lexani Solar chrome wheels, and will be buying adapters to go from the 5x5 of the GMC to the 5x4.5 on the wheels. The wheels themselves have a +43mm offset.

Any help would be greatly appreciated.

I'm sorry I can't help you with that question cruiser, but I can say that those are some sweet wheels.  I hope some one here can help you,  if not you'll probably have to call a wheel manufacturer.

I now know for a fact the optimum backspacing is 4.5" for my truck.

These wheels had a backspacing of 6" and I had to get 1.5" adapter/spacers to make them work.

Thanks
