How did you measure the tire diameter?

Your kidding.....right? Take a tape measure and see how tall it is.......

..Diameter is also affected by rim width. Wider wheel = smaller diameter. ..

Uhh..., I dont think so. How does a steel belted radial shrink? The sidewall varies to accommodate the rim width...

"... Note: Because the overall diameter of a steel belted radial is determined by the steel belts, there is little, if any, change to the overall diameter of the tire due to differences in rim width." https://www.tirerack.com/tires/tiretech/techpage.jsp?techid=194

Now remember that these tables from Mopar were using bias ply tires that sat higher than a radial with its flatter and larger contact patch. So a "24 inch" bias ply tire may be in fact a 23 inch radial as the car sits. Maybe that explains the 1 tooth difference in Brewers and Mopars. Run your 35 and tell us how it worked.
