GM did have tires with something like 60% less rolling drag than conventional steel radials of the day.I suspect that this gap has closed since 1991.  |
That is great news, aerohead! So I could be looking at having a 100+ mpg car if I max the aero out. Just the motivation I need
It is good to hear that my frontal area will not differ very much. I was concerned that it was already a penalty to overcome. What I do have planned to help lower FA is the give the ZX2 a Probe IV treatment. I plan on lowering just the front, and maybe lifting the rear 0.5-1" ONLY if it would help aero.
I suspect the same as well. Sounds like they had RE92s haha. I plan on going with them as my next set of tires, unless there is another tire with lower LRR.
