Hi,my name is mike and I will assist you with your question.
The 45 will be not quite as wide as the 40 and will be slightly taller. As far as at making a difference as far as the ride of the vehicle because it is taller the ride might be a stiff,meaning going over bumps would be felt more with these tires than the ones that you have on it. Both sizes will work on this vehicle.
