Do you change all four of your tires?

My wife drives a 2018 Envision but I would have to do some reading as to what kind of coupler they use between the front and rear drives. If it's a fluid coupler with some slip, tires with slightly different diameters wouldn't be an issue. If it is a solid or mechanical coupler, They should be very close to the same diameter. We just turned 60,000 on the odometer with the original Hankook's and it's time for some new rubber. The fronts are worn 1/32 more than the rears. Nothing a grand $ won't handle.
