Tall Skinny Tires Are Best !
Yep ;
You can use the various truck 16" wheels , GM used several different vendors for these so don't worry if the ID stampings are different . most wheels made in America have the ID stamped near the valve stem hole .
Passenger car wheels also fit from the 40's , they were 16" untill '48 or so .
Adding the hub cap clips is pretty simple if you buy a later wheel with the holes drilled but no clips .
If you go to the older junkyards or farm supply places , you'll usually find a huge pile of wheels with rotted tires still on them as they're considered Haz-mats by the scrap places ,wear grubby clothes and go digging , carefully as there's often various nasty spiders and scorpions etc. hiding but the result will often be a full set of 5 matching wheels On The Cheap , have your local powder coater re-do them in the color you like , for under $45.00 per wheel this should include all cleaning and bead blasting for a show quality wheel .
As mentioned , look carefully in the valve stem area for deep rust pitting , also in the lip where the tire bead seats ~ some pitting is O.K. but not deep pitting as this is where rims split when they get too rusty . (BTDT no fun)
The correct size of radial tires is mentioned elsewhere on this site in the archives , if you get good quality LT rated tires , they'll not only look good but will outlast passenger car tires by a wide margin , $aving you $ in the long run .
Just tires and America's Tire Store , plus many ohter chains , sell the correct size in Dayton for $75.00 ~ $85.00 each , list price .
They'll have to order them in but it's no biggie , apart from what a lazy salesman may tell you .
Thought I'd just say welcome.
I already have the original GMC hub caps. I'll need to check if they'll fit the Chevy wheels. I'm sure they will though.
