Nope they will need to be bored.

 

are we talking about a lot or is it pretty much just a matter of dusting out the ID. I'm just worried about making them weak.

 

I believe the Tahoe wheels are 78 mm bore and the Colorado wheels are 100mm bore. They only need to be bored about .400 deep from the backside and an 1/8" chamfer around the hole. They'll still be plenty strong enough.

is this the exact specs or just an estimation? if so good information that should be stickied somewhere because this comes up often.

 

Does anyone know where I might be able to get this done in Michigan. I know plenty of machine shops but they would all charge a fortune for someone off the street. I'm looking more for the case of beer a few bucks type of arangement. Let me know

 

I'm a machinist so I bored my own wheels. I bored them to 3.940" by .400" deep with a .125"x 45 deg. chamfer.
Spudman, if you lived closer to me I might bore them for you.

 

I was wrong on my dimensions. I just checked my wheels and I went .625" deep on the bore, not .400" like I previously stated. So it's 3.940" diameter x .625" deep with a .125" x 45 degree chamfer.

I know this is an old post, but came across it for some reason. Instead of boring, buy a cheap set of 1" spacers. You won't have to worry about the bore and it gives the truck a more aggressive look.

As has been stated in several other threads, if you choose to run spacers it's recommended to add to your maintenance list 'retorque wheels'. Anybody who has spacers will generally pull the wheels and torque the spacers at oil change intervals. This is for safety reasons.
