my suggestion is to look for some Hummer H3 rims. They are the same hub dia (~101 mm) & bolt pattern (6 on 139 mm) as The Twins & are a bit wider to boot. I got a set of twin-spoke 16" H3's for a spare set from an owner who never left the Hummer pkg. lot with them on (N.O.S. take-offs) but haven't used them yet as my stock 16" Canyon 5 spoke alloys still look good to me. There are a lot of ugly stock Silverado rims to be had cheap even if you have to bore the hub hole bigger (see the How-To's on here or 355 nation-the other guys), try the local buy-lines/craigslist, be patient & make sure any wheels you buy you put 'em on a wheel hub & spin 'em to check for runout/bent rims etc. I rejected some 18" forged wheels because of defects I found that way. You should be able to find some decent rims for $200 or less if you just keep looking.

 

The Silverado forum mentions the Titan rims fit the Chevy trucks. Since the Silverado wheels fit the Colorado (with minor center bore opening), maybe a Titan/Frontier wheels will fit on a Colorado.

 

If you search the website for your topic you will find all the info you need, be productive and do it. The "other guys" @ 355nation.net also have all the info you need by doing the same thing there.

 

and other chevy (gas) just might have to be bored...then u have nissan rims....titans, armadas, and exqs or something like that....which will also need to be bored...but the only one that fits straight up, will be the hummer rim...and like said above...move over to the nation, they can help u alot more....

 

Bolt patterns at least will be the same on late Toyotas as well. You could also try Isuzus.

Oh, and full size Jeeps from about '76 and up.

 

Got a full set of Z-71 rims with tires for $100
