Soft or firm depending on the application, Cadillac or Corvette/Sportscars. Now we have the new generation coming out with 17-18-19-20" wheels with 30-40 series tires that have no sidewall give at all, it must be all in the suspension. It seems to me that if you go the larger wheels/small sidewalls on an early car your suspension will not work at all. Of course we can procrastinate and say it's just stiff because it's more like a competition suspension.

Just my opinion
You have to remember that "modern" cars have a suspension sub frame that isolates much of the tire's ride harshness.

Don't most race cars use 18" wheels? Seems >18" is just looks.....

BTW, I LIKE my 16" wheels.
