According to the tire size calculator, it's a 0.9% change in diameter. When I sat in the car, it 'feels' a teeny bit taller. Maybe it's just me thinking too much, haha.
According to online specs, the tires on the VX wheels are considered LRR. It definitely rolls much better than the snow tires.
Yeah, if I had 165s on versus 175s, I'm sure the RR would be much better. According to the MPG gauge, I'm getting better mpg's overall. But I'm assuming the overall mileage I get from the tank of gas is higher because the wheels are spinning just slightly faster...?
