Ken,
I'm thinking the 70-85's Newells had 20 or 22's. I believe the 22.5 did not come out until the mid 90's. I was told that the 22.5 came to life because they have less rubber hence lower FET that the existing 24.5's. From what I have seen, it seems that all tire development past that point was done on the 22.5's

However, in 1984 I had the new Michelin Pilot 70 series x 19.5 put on my Pace Arrow. Seems there were 22.5 available then?

I'm getting old .......................

"From the mid-70s through 1985, Newell installed 11R22.5 Michelin steel belted radial tires with excellent results. With the upgrade to the 8V92 engine in 1985, they began fitting 11R24.5"
