Looking to go to a staggered setup on my G37x...tires/wheels fit but there is a 4 revs per mile difference between front and rear

fronts are 245-40-19 and rears are 275-35-19

speedometer = 60 and actual speed is 60.3

diameter, circumference, etc is only millimeters

but....will 4 revs per mile have any negative effect on the Infiniti AWD system?

 

it only makes a difference if the rolling diameter of the times is more then 5% different or maybe its ten. Someone who has more experience then this will chime in. BUMP

 

front diameter is 26.71 inches...circumference is 83.91 inches

rear diameter is 26.57 inches...circumference is 83.47 inches

looks to be considerably less than 5%...actual diameter difference is .5% (one half of one percent)

 

Your good tO go then!

 

Official word from Infiniti customer relations technical division (800-662-6200) is that we may put any wheel/tire combo on the AWD as long as the overall diameter/circumference stays the same as stock.
