If all replacement tire sizes must match the sizes printed on the vehicles tire placard, why do we plus-size assemblies on custom wheels?
Remember, the vehicle’s suspension and steering system has been designed specifically for the size tires listed on the placard. Changing tire diameter beyond this point can adversely affect vehicle handling, antilock brake operation, and speedometer accuracy. However, as long as the outside diameter of the original equipment tires is maintained within 3%, the plus-sized custom wheel assembly should not cause any problems.
