Tire Clearance?

[Rojo]

What is the "proper" tire to fender clearance for a leafspring rearend. I am building a chevy truck with 20x12's in the rear and its kinda' tight.

Thanks

It looks like the tire bulges out past the fender lip. I would at least roll the lip to provide a friendlier surface if contact is made.
My '95 is set up with about 1/4" clearance from the fender to the tire but the tire is tucked inside. I have had no problems with fender rub.

The tire tucks under the fender just fine. Theres just not much room.
I was wondering how much room I should have. The "buldge" of the/sidewall is about 1/2 from the fender when the rear is lowered.

1/2 in is plenty of room, especially on a leaf spring rear.
