+1. This is why I demonstrated how rounding and approximation were used in my process.
Despite the shortcomings (I find the values to be low for wider tires)...
Funny, I find it to come in high. Compared to the calculated suggestion of 38/52 I found 35/40 to be very good for my commute. In particular, there is a triangular steel bar that I have to roll over (it is the track for a mechanical gate at my work), and 35/40 it absorbs the impact very well without bottoming out. Even 30/35 does not bottom out, but it feels like it is getting close.
