You only need enough contact patch to stick the supplied torque on a consistent basis. Anything beyond that is dead weight to pull. WAY too many guys put more tire on their cars than they need as a crutch for a poor working chassis.

Lots of bracket guys are among the "stick and go" persuasion......meaning put a big enough tire on there that you pretty much dead hook it, regardless of track conditions and never have to worry about wheel spin. That's fine if that is the route you want to go, but even at that, if a 14x32 will get the job done, a bigger tire won't help it hook any better and will only slow the car

Now where some of this goes completely out the window, is cars with a LOT of power. Many of these cars will NOT work with the tire dead hooked. They want to shake. In those instances there is definitely a such thing as too much tire
