86 C-10 max back spacing???? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**youngrodder** · 08-31-2007, 11:26 PM

We lowered my neighbors truck in the front tonight another 3 inches with springs. He already had 3 inch drop spindles.

Here is the question......what is the max size tire and rim size for a 20" rim including backspacing? He currently had a 15" x 10" rim (4" back spacing) and a 275 x 60 x 15 tire. The top of the fender rests on the top of the tire.

He plans on buying a set of 20's.

Thanks

I think its 5 or 5.5"

5.5 works well with a 10" wheel
