It shouldn't rub but it doesn't mean you should use it. It's way too tall hereby affecting acceleration, braking, handling, turning radius, gas mileage, suspension geometry, speedometer calibration, etc. Best to stick with factory recommended size for optimal overall performance.
my girlfriend has a gxp like mine, 225/50r18 was stock size wanted to go to a different size..we test fitted 225/55r18 and they do rub on the front fender and rear also. it is best to stay with stock size or go wider not taller, 235/50r17
