Have a 2005 Silverado 1500 4wd with 17 inch rims. They are OEM rims with OEM center caps. Problem is the plastic lugs that hold the center caps on won't go over the main lug nuts. They worked until three years ago when I had new tires put on. Bought new plastic lugs and still won't grab the threads on the main lugs. Have had several people who are experienced look at the issue. One says my chrome covered rims have expanded where the chrome is plated over the steel rim. Another says it's the main lug threads. Tried one new lug but no change. Everything is OEM so cannot figure it out. Worked for 14 years. Any ideas?

I bet the thread pitch/count on the lug nuts is different from OEM, even if the internal threads are right.

Who put the tires on? Did you physically see the lug nuts through the entire process?

Not trying to be argumentative. Just looking at options.

No worries, I appreciate your time and input.
It was done at BJ's tires. I didn't watch them when they did it so I guess they could have replaced all 24 lug nuts but they didn't look new then or now. That is what is so perplexing about this.

Yes they do. The plastic ones that go through the cap are new. Compared them in length and thread depth to the originals ( which I still have) and they are the same. Even tried putting the originals back into one of the caps but still same problem. Only suggestion I got from a repair shop I use when the problem requires more specialized tools than I have is the rims have expanded where the chrome overlay is attached to the steel rim itself causing the caps not to go as far back as they used to. Looking at them it doesn't seem to have done that but the steel is rusty. No way I can see to fix that other than new ones. Expensive at over 350 pr.

Wow. I’m sorry. I don’t have experience with those wheels. My neighbor had a truck with them. Never understood the logic of an overlaid “hubcap”.
