TC Spec Tires: Hard or Soft?
As one of a few people who had the privilege of running both the Mile High Indoor Champs and the International Indoor Championship in the last year, I ran on two different sets of Gravity spec tires in touring car. Between April and October there were quite a few changes to the Gravity tire in that it was much softer and made much more grip at the IIC than it did at the Mile High. I have both sets sitting on my desk as I type and by my reckoning they have had roughly the same number of racing laps turned and, naturally, the IIC set was much more grippy, softer, and has much more wear than the Mile High set.
The point of this thread IS NOT TO CALL OUT OR OBJECT TO DECISIONS MADE BY GRAVITY RC. They made their tire formula changes for good reason, whatever it may be. The point is to ask:
Do you think that a "spec" touring tire be intentionally harder and lower-grip than optimal? Especially on high-grip carpet surfaces?
I loved racing at the Mile High even though I never found a good setup. The harder tire with a hard sidewall meant that you were tuning your touring cars the way I think you should: tune for more grip, not to fight traction roll. At the IIC I had to glue sidewalls to prevent rolling in high-grip corners like the rest of the racers, and this dictated most of my tuning changes. I didn't have to glue sidewalls at the MHIC, nor did other racers.
I am a proponent of the harder tire, personal preference.
Also, I should say that I am a BIG proponent of spec tire TC racing, because for me it makes tuning much, much easier if I just KNOW what tires I will be running instead of having to play Musical Sorex to find that extra tenth.
I race toy cars for fun. If I need to explain, you'll never understand.
