What bolt pattern for my 2001 Silverado 2500 HD?

I drive a 2001 Silverado 2500 HD LS, and I’ve seen online that my truck’s bolt pattern is either 8x6.5 or 8x180. Can anyone confirm which one it is?

I’m pretty sure they were 8x6.5 until 2010, then by 2011 they were 8x180. There were also a lot of other small frame and suspension changes during that time.

That’s kinda what I’m seeing online too. Just hard to find something that actually confirms that.

I owned a 2002 that was 8x6.5 and a 2011 that is definitely 8x180. Not backwards compatible, I can tell you that with 100% certainty. I’m just not exact on what specific model year they switched.

Sweet, thanks man. That’s all I needed to know.

Yeah, I had the same question when I was looking for wheels for my truck. It can be tricky with all the info out there.

If you’re ever in doubt, just measure the bolt pattern yourself. It’s pretty easy to do.

Good idea! I’ll keep that in mind. Thanks for the tip.
