One of the most common questions for classic C10 builds is what tire width you can run without rubbing. The answer depends on your ride height, wheel backspacing, and whether you’ve done any body/fender modifications.
This thread is a comprehensive fitment guide for classic C10 tire widths at various ride heights and spring drops. We cover stock height, 2" drop, 4" drop, and slammed setups with specific tire/wheel combo recommendations for each.
For trucks that are lowered 3-4 inches, the Pomya Suspension Lowering Kit for 1963-1972 C10 (3" front / 4" rear) is one of the more common drop levels we reference for fitment in this guide.
Post your tire/wheel combo with your ride height so others can use it as a reference.
