I wish there was a general rule of thumb for this. XXX cm of sidewall is good for comfort. YYY cm is good for handling but harsher ride. ZZZ cm is super comfortable but has a lot of side wall roll.

The closest I could find was a reference to a luxury package tire size for a Cadillac CTS that had 123 cm of sidewall height. I do the math with certain combinations of sizes that keep me under the 25" total diameter and almost all are auto cross or track use only. At least at TireRack. To get that sidewall height in a 16" tire is nearly impossible and the 15" ones are track tires.

Miata's and RX7's must have a similar tire size. I wonder what those guys are using for daily drivers and highway cruisers?
