Will these newer style Silverado 6 bolt wheels fit on my 69 GMC 1/2 ton?

Tires are BF GOODRICH RADIAL LONGTRACK T/A 245/75R/16

If I remember correctly, the center bore is too small.

If it helps any there are off of a 2001 Silverado.

i have heard the same thing, the center bore is too small, and i believe the ofset is not correct

Lots of off set in those newer wheels, something like 5".

I've heard of guys having the centers machined out to fit.

Not looking for a lot of work, just a deal on a set of wheels and tires.

I tried the use the ones off of my 2003 Silverado on my 68, and thats when I found the center bore to be too small. The bolt pattern is metric (I think), but will work. Might be worth a call to a couple of machine shops to see what it would cost to chuck them up in a lathe and open them up a bit. Would be really easy if you could find a lathe with a big enough swing.

All replies about the center bore being too small are correct. I ran into the same problem with the wheels I'm currently running. I chose to pull the axles and have the flanges machined down to correct it. Up front I was fine since I have a late-model disc conversion. I am running 1-1/2" spacers out back to correct the backspacing issue. Up front, no spacers as the drop spindles and disc conversion already gave me a wider track width than stock so it was fine.

Center is too small. Had the exact same wheels. This is what I found. Offset looks goofy on the rear. On the front the wheel rubbed the control arm.
