Comparing a Firestone dt radial 620 has a flat plate of 475sq in, to a Firestone 23 deep tread 480 has a flat plate of 380sq in. That is a sizable difference but a lot of variables here. 25 percent more tire on the ground at lower psi, but those deep tread 23 on a ripper in wet conditions would really go!
