73-87 Chevy _ GMC Trucks > Wheels & Tires

Will these wheels work with my setup? 79 C10


Iím pretty sure this will work but want to double check before pulling trigger. Iíve never bought rims before.

I have a 79 step side Silverado.

Iíve lowered the truck 3/5 (used spindles in front and hangers/shackles in rear)  Might go another inch or two depending on the stance one I get the tires on.

Iím wanting to put the Ridler 695ís 20x10 on it. Tire size will probably be 275x45x20.

Do I need to worry about offer or backspacing or anything? Iím struggling to understand these and how they work.

Appreciate it!

I'm sure there are more knowledgeable on this subject than I am, but I can offer a few guidelines.

ON the Truck: You need to find and measure the center line of your wheel wells. That is the mating surface on your rotor and brake drum.

From that point you need document the distance to both the inner and outer fender from the Center Line.

ON the Wheel/tire: Measure the distance from the mating surface of the wheel to what will be the back of the tire. Subtract those inches from the overall width of the tire. (Assuming you have that data)

Draw out the rotor center line and fender distances. Draw in the wheel dimensions. You will see if you need spacers.

That's a start, now you will need to see if the tires will clear or Rub... ;)
