Newer wheels on a old truck???

    As in my profile, I have a 1990 C1500 2wd V8 5.7L and now only 60K miles on it!!! I have been looking at upgrading my wheels from the factory steel wheels to some factory aluminum alloys. This truck comes with 5 lug 5" rims. The 15" Al alloy wheels must be rare for this lug spacing cause the cheapest I can find them are $190 per rim. However, I can find alloy wheels from newer models all day long for around $100 or less.

    How much trouble is it to change from the 5 lug pattern to the 6 lug pattern? how reliable are adapters? I hear stories of them breaking while driving. And all the hubs I find with the 6 bolt pattern say they are not compatible with this truck. Hmmm!

    I know plenty of people here have put bigger rims on there K1500 but I do not find anyone putting bigger rims on their C1500s. I am only looking to go with 16" factory wheels. Any suggestions are appreciated!

    Thanks and Merry Christmas

    You may be able to find parts from a C1500 Tahoe or Burban that will fit. They will be exactly the same as your truck. The Burban and Tahoe have 6 lug hubs no matter what. The Burban with you body style came out in 1991. So look for parts for a 1991 C1500 Suburban (hubs, bearings and such).

    No they don't. on the OBS trucks and SUVs, only the 4x4 vehicles have 6 lugs. The 2 wheel drive OBS models were all 5 lugs. Tahoes and Suburbans included. that didn't change until 1999 on the trucks and 2000 on the SUVs.

    Are you sure because when I was looking at trucks I looked at a 2wd Tahoe that has the same 6 lug wheels as my current 4x4.

    Absolutely positive. If it was 6 lugs on a 2 wheel drive, it was modified to be that way, unless it was built after 1998.

    I think they exist but only with the SUVs I remember because I was happy when I saw the truck because it was the perfect price and was in great shape until I look underneath and saw there were some major parts missing. I will find proof once I get on a computer currently I'm on my phone.

    Remember I'm not saying your wrong you sure as hell might be right but I remember seeing a 6 lug 2wd truck in person that was OBS.

    I give up...

    Ok, it turns out we are both right... They exist as both 5 lug and 6 lug depending on the packages and equipment they have. The higher trimmed trucks have 6 lug while the WT has 5 lug from what I can tell.

    In hind sight this argument has gotten us no where closer to helping the OP get new rims and find a way to mount them.

    I researched the factory shop manuals. No 2 wheel drive OBS 1500 series vehicles had 6 lugs ever. 2500 series models had 8 lugs.

    I was not arguing or attempting to start one. I stated what I knew to be correct to begin with. When I was told I was wrong, I posted what I posted to avoid saying something that would have been guaranteed to start an argument.

    To the original poster, the wheels from any 2 wheel drive 88-98 1/2 ton truck, SUV or van will fit fine.

    Moogvo is right... 2wd was 5 lug... 4wd 1500 had 6. 2500 and 3500 had 8... And, I'm pretty sure they had some 2500 that were 6 lug.. not sure if it was because they were 2wd, or considered light duty, or something like that..
