Would an extra 2" of tread width help?

Depending on what the tires actually measure, could be 2” per side, or 4” total . I was always taught to put the biggest, stupidest tire on. If I was worried about the 60 foot change with bigger tires, I would change the rear gear to compensate. A friend of mine built a Monza, with a small block, powerglide trans 9” rear and 15x 33 tires. He talked about changing the 1st gear to a 1.69, to dead hook all the time
