I'm trying to find a cheaper wheel option. Kaiser Willy's has their vintage tire but that really adds up with shipping. If you look at this vintage tire conversion chart, they say that 5.90 x 15 are equivalent to : 75 series P165/75R15 | 70 series P175/70R15, but instead if you look at Les Schwaub they say the tire is a 165/80R-15.

Looking at auto-catalog includes tire-sizes but they don't include the profile?

If you use 165/80, you get a side wall height of 5.2 in, and then a total wheel diameter of 25.4 in (vs 25.6 originally) This is only a 0.7% difference in diameter.

The original tires were 150mm / 90 or 150*.90 / 25.4 = or a 5.3 sidewall which should be a 25.6 diameter as specified. but closer to a 10% difference in wheel width.

After all that, the rims were actually 14" and not 15". So I had to go with some completely different tires. In the end, I got P205/70R14 95T Sailun Atrezzo SH406. These were about $64/per.
