I picked up a 2007 Avalanche a couple of weeks ago, and it's got a few issues. One nagging one is it looks like I THINK after-market 20" wheels have been put on, but the center caps are missing! The center cap appears to measure 3 5/8". Anybody know who makes these wheels, and where to get center caps, or if these are a optional factory wheels? I can't find any manufacturer markings on the front or inside lip. Thanks!

EDIT: I should add that the RPO codes in the dash label indicate it came stock with 17" aluminum wheels.

 

I took one of the wheels off last weekend. What an immense pain! I couldn't find any maker markings on the inner spokes. I did find a "Made in China" mark (of course), and tire rating and vehicle weight. Also a couple of other numbers that didn't turn up anything upon a search. Ahh well... time to start ordering random center caps

 

Okay, I pulled a rear tire of tonight. It was slightly less corroded, and I took some pictures this time. Maybe someone can identify them or point me in the right direction?

Below: Looks like "C 24HUx 4" x obviously being I'm not sure of the character.



Below: "H 162502" (not sure about the '1'.")



Below: "ET 52 HT-03"


Below: "DOT-T" I assume that's the speed rating.



Below: "PCD 38"



Below: "MAX LOAD"



Below: "2200 LBS"



Below: "20X8" It might actually be a "9".

Below: "06 07" followed each by a bunch of squares. Manufacture date perhaps?
