Wheel help for an old GMC
 

I have a 79 K2500 and need new tires. I have found that with the current size I am extremely limited. 9.50R16.5 I am thinking I should change the wheels to a more standard size.

So, the question is what years wheels can I use? I just want plain steelies or cheapest possible.

Thanks!

If a 16 inch rim will fit it will give you more options.

That's exactly what I am trying to find out.

If a 16" will fit - and if so what years should I be looking for to try to get some salvage.

These are 8 lug hubs, btw.

Here is one set of 16 inch rims on ebay. Usually a local tire and used rim shop will have something. Take your old rim in and match it on back spacing and center hole size. A 265/75R16 (that a 32 inch tire) is common on the newer trucks so a 7 or 7.5 inch rim width will be OK. You need to make sure it will fit without rubbing anywhere.

Here is an ebay sets of rims.

My sources says if your salvage yard has any Chev 3/4 truck from 1973 to 87 those rims should fit your 8 on 6 1/2" pattern.
Ask them if you can check, before you commit

you can buy the steel wheels at the tire shop just tell them what you want. steel wheels are not that much
