According to a review on Tire Rack:
https://www.tirerack.com/tires/tires.jsp?tireMake=Goodyear&tireModel=Eagle+F1+Supercar+3
Tires usually do make a huge difference in a car's performance, but I think it's being overstated in this case. The MPSC2 has been on the market for a long time. Goodyear's F1 Supercar 3 tire is brand new. No doubt it has more modern materials, technology and construction. It might very well be nearly or just as good as the MPSC2.
So can we put the tire debate to bed and focus on the many other aspects of these two cars that would put them so close to each other?
Yea, because a random tire review on a website, where a guy says "gives cup2 run for the money", WITHOUT ANY ACTUAL TEST DATA, constitutes law.
You guys crack me up.
