Any opinions on running 28x12.0-18 on the rear and 28x10-18 on the front. My '76 is lowered on Ridetech airbag system. I'm open on wheels as yet.

OK, no takers. What if I said 285/45-18 rear and 265/50-18 front? These are close in metric

This seems to answer the question, not the same numbers but overall size is the same for the front.

This is live85's truck with about a 4/6 drop and my 20's on them with 275/40/20's for the Boss 335 15x8.5 wheels with 5.670" backspacing for those wanting info on a lower setup..

The front at 10" wide will probably hit. the inner fender depending on how low it is.

Not going to run factory inner fenders, just some steel trailer fenders. What do you think?   :-\

It should be ok if you mount them high.  Just verify your backspacing and clearance to the fender lip.

Thanks Cap.  8)
Can I assume the backspacing on the white truck (5.670") is good for the 18x8.5 front wheels, Same for the 18x10s in the rear or a little less say 5". It's a Stepside.

you should be ok.  I would still measure though and keep in mind the tire height.  Those are about 28.5" tall.
