Lexus uses only run flat tires which is a step away from achieving the best available ride. Those tires should only be an option. They are noisier and give you a bumpier ride because they have Rock hard sidewalls to support the vehicle when all the air leaks from the tire. Also because of this the car is less safe because as you hit bumps the tire will not maintain the same ground contact that regular quality tires will give you. Run flats have a better chance of your tires becoming airborne rather. I will never buy a car with run flats. Even if it is a $30,000 vehicle. Lexus is a $70,000 CAD plus vehicle 👎👎👎👎
