I have 6 / 15 x 7 SS rims . Before i put more money into the SS rims i had them all tested at a tire shop . All 6 had a slight hop. A bit out of round / not true . Tire shop said this was normal for rims of that vintage . I then had them all sand blasted. Part of the reason i purchased the SS rims was i could not find a plain 1982 rim . local Tire shop said the 15 x7 original rims are now rare and hard to find . My original 1982 rims were all leaking air in the winter time . So decided to put the SS rims on the car while i get the original rims sand blasted and painted . Had all 4 original plain rims tested for run out , they all checked out to be true / no hop . Question , for long road trips , would the original rims be better ?

Next observation .
The centre hub shape of the SS rims are different than the centre hub circle of the original plain rims.
Question , does the weight of the car sit on centre hub circle of the original rim ?
Now have the SS rims on my 1982 Delta 88 , Q ? is all the weight of the car now on the wheel studs ?

It seems to me they do sit on the center for the original rims. Yeah, it seems the SS rims can be a bit out of round. As long they balance, they should be fine.

Had an SS rim and a plain 1982 original rim to a tire shop . They say the SS rim only sit on the wheel studs . They say when mounting the SS rim that only sits on the wheel studs the wheel can be a bit off true . The SS rims are already off true from the factory , now one more off true when mounting ! The original rim sits on the centre hole but also it keeps the rim centre/ true . Shop said original plain rims are stronger as the whole inner face touches vehicle so no flex or possible bending . So sounds like the plain original rims are better for long road trips.

You might ask them to "index" the wheels, one wheel stud at a time, to see if it takes some of the out of round out. By that I mean to remove the wheel, rotate it one wheel stud and put it back on. Sometimes that helps.

Index the wheels , that's interesting thanks .
SS rim VS plain rim , so far the original plain rim seems to be the better rim .
So are there any advantages of the SS rims other than appearance. Maybe more cooling of the brakes do to the 5 bezel opening's / more air flow .
