Sorry, that's a GSP9700 term. . .
that essentially means the machine can check that the tires out-of-roundness [oor] and weight balance testing.
3 of the 4 tires that were 'given' to me when I bought the car failed this test. Plus the balancing of these tires is almost impossible. So the car had great shimmy/wiggle in the steering wheel at 55 - 60 mph.
So the dealer (Discount Tires) gave me an adjustment for the new tires (very reasonable). Then when balanced on the Hunter, the car shows no 'shimmy' or steering wheel 'wiggle' at any speed.
You are correct that the 140 series is very 'sensitive' to any imbalance in the tires and/or wheels.
