Re: wheels rubbing lower control arm

In the photos you can see I have 1/8-3/16" clearance between the inside of the wheel and the lower control arm. I've been told this is "too close for comfort". I say clearance is clearance. Any thoughts?
My opinon is 5" backspace is perfect for 17" and larger diameter wheels,... but too much for 15" wheels.
I consider 4" the max backspace for any 15" wheel up front.

Put your truck on jack stands under the frame near the front cab mount.
Then use a floor jack to "cycle" the a-arms up and down.
I bet you get some rubbing hard on your wheel.
Also steer the truck left and right to see how that affects the contact points.

I would be looking for different wheels if I were you.
