170220 FORUM

I should have checked my reply.  Only half of it got posted.  The most relevant parts didn't get included for some reason??

Yes, I have standard rims.  Three appear to be newer than the fourth, but they have been fine.
Tire size 185/80R15 or 185HR15 is pretty close to the size of original bias-ply in height and not too wide for fenders.

I bought two sets over the years.  First was Federal brand, and second set was Vredestein.  Diamondback uses production run tires and will customize the sidewall to your choice.  I have a 2.5" whitewall added and it looks great.
The company has been great to deal with from helping to source the tires and prompt service.

I believe Coker also is a popular company, but I have not used them.

I'm sure there are many different opinions on this topic, but since I also have a '52 220, here is my input.
First of all, I'm not sure what a Safety Rim looks like.  Three of my rims are similar and one is, I assume, is an older version.
I've never had an issue.
I drive quite a bit and also wanted a radial tire, but finding a radial with similar physical dimensions as the original bias-ply is a challenge.
I think a 185/80R15, or a 185HR15, are good choices.  I have had a set of each.  I buy my tires from "Diamond Back Classics" because they use modern production tires and will add the 2.5" white wall that I want.
This is not a common size and my last set had to be special ordered from Europe.
The two brands that I have bought were Federal and Vredestein Sprint Classic.
It has been 5 years since I last bought tires, so things may have changed quite a bit.
Another company that may have a size you need is Coker.  But I've had great luck with the Diamond Backs and they have always been very helpful sourcing the size I need.

Could we get into the habit of copying and pasting the actual text of the ad in these type of links? The links tend to go away and then there is nothing to look at and reference later.

Thanks to this forum I ended up buying Richards car in Texas. It is now sitting in my garage next to the Cab A and I am hoping to dig into it soon. Seems to have good rust free bones but lots of other loose ends.
