Question:
On a 95inch hub face, 3500, 4inch axle, what is the maximum outside frame width before tire rub becomes a concern? 225/75/15 tire and wheels.

Hey Bill,
A 225/75R15 tire would have a 9.25" width and you need to have a minimum of 1" between the tire and frame so we'll add the two together for a 10.25" space needed for the tires on both sides. That being said you also have to figure in where the spring seats can sit on the axle, which can affect the frame width as well since spring seat have to sit in the middle of the frame rails.
The spring center for a 3,500lb axle with a 4" drop would need to be spaced from the hub face a minimum of 14" to a maximum of 23". Going outside of this range will throw off the leverage and likely damage the axle/spindle. Just going with the 14" minimum your frame rails would need to be centered at 67" apart.
If I made this more confusing let me know and I can explain this more.

Do you mean centered at 87? 67 doesn’t sound right
