Probabl not much, maybe some reduced gas mileage and slightly less performance when pushing the car.
It's kinda funny that some people will buy a Bimmer and then try to save money on gas. Even if you drove a lot like 20k miles I think you would save about 170 bucks a year. Or 35% of the cost of 1 RFT tire.
