A question, just to be sure... In previous GT, there was only a color (temp/grip) and gauges (durability) for the tires, now we have: - color - number - gauges If I understand, now the colour mean the tire grip + spec, the number mean the tire use and the gauge.. What does means the gauge, temperature ? In fact, I don't understand any of these. Can somebody clarify this ? That changed too much from previous GT and I didn't found the explanation.
