Question: how much bigger is a 37 tire than a 35?
Answer: Larger tires also take a greater toll on an automatic shift than a manual. ... Taller tires generally reduce braking and stopping your truck or Jeep will take more distance. “You're really only gaining an inch of ground clearance when you go from 35-inch to 37-inch tires,” says drivetrain expert Rody Jarve.
