Here it's getting harder to find stock steelies at a reasonable cost for old square bodies--yesterday I took a hike through my favorite salvage yard and saw maybe 4 square body trucks,and only 2 of the 1/2 ton 4x4's had any rims or tires on them...their inventory of taken off rims is now sparse,used to be a huge pile of them and racks full in a barn,but I guess they scrapped a lot of them as demand faded and scrap prices shot up a few years ago..
Now all the salvage yards seem to be scrapping any rims off old trucks and only keep ones off late 90's and newer vehicles,mostly the factory alloys rather than steel rims too...and they aren't giving them away,prices start at 50 bucks here for most any rim..
Here you see more 17" tires lately than 16's,I have a set of 4 B.F. Goodrich 245/75/17 tires I cant use because rims for 17's that have enough offset on later trucks wont fit my '82,and I dont have a few hundred to buy some that will work,so I'm going to try selling the tires..
I went hunting for some good 16" tires and found a few dozen that looked brand new on junkers,but had been sitting out to the weather so long the sidewalls were all alligatored...it's a shame they dont take more tires off vehicles at junkyards..sometimes you'll come across brand new spares still in the under the bed tire carrier,but they want 100 bucks for a "new spare" and charge you for picking the truck up with the loader..
I never liked 16.5" tires,they came off the bead too easily on most stock rims,that lacked a safety bead..
I had 4 Cooper 8.75/16.5's I bought a set of 4 bias ply ones brand new on my 71 K5,on 6 lug drop center rims,that were a rare factory option..those had safety beads --they worked good but the nylon corded tires felt like square wheels the first 15 miles every cold morning..
