Hi Larry
Again, I would like to mention that the experience I have had is with Goodyear tires, other brands have usually not been a problem. 4 grams of weight is a perceptible amount when the wheel is mounted on the front of the vehicle.
When you make time for this experiment please let me know what your conclusions are with Goodyear tires. I agree that mathematically it should not matter but how many times has theory been proven wrong by reality?
