Where can I find steel 16x8" 8 lug wheels for 2500HD

Try your local junk yard, it should be full of them.

Try craigslist, there are tons of guys who just can't resist buying a $xxxx set of fancy wheels, they need to sell their old wheels to offset the cost of the new very expensive wheels. The dealer may have some steel wheels that are used dealer takeoffs, and will carry a lower price.

Rock Auto parts has had some good prices on new replacement wheels. Shipping will have to be factored in.

I have had good luck with craigslist. I would not buy a set of wheels off of Ebay unless it was also local. It costs a lot of money to ship a wheel.

Also, some Dodge wheels will fit older, GM 8 bolt trucks. This gets tricky because of bolt covers.

Finally, GM in the past 2-3 years changed its bolt diameter. Older wheels do not fit newer trucks without an adapter and vice versa.

Good Luck.

You might try Southwest Wheel

A 3500 will have the wider steel wheels you want. So start calling wrecking yards and ask for 3500 SRW wheels.

Try Mickey Thompson or Pro Comp

Junkyards should have plenty of them; 2500 work trucks generally have the steel wheels as standard equipment

Sometimes you can enter too much information for searches.

Check e-bay, your local salvage yard.

Since the internet isn't producing results, try the phone tomorrow. Call some of the local tire shops or four wheel drive shops and they can probably tell you where to get them locally. Also call the dealer for your brand of new trucks and tell them what you want to do. You should ask for their commercial fleet salespeople. Ask them who puts on the fleet accessories like flatbeds, fleet mechanic's beds, dump beds, tow truck beds, etc. You want to find a shop that does commercial service truck modifications. They'll probably have the rims on hand.
