This is true, but on my 2013 GT500 I ran the 305 M/T SS tires on my stock wheels and the car never swayed at all, I than put them on my silver GT500 and they were terrible, the car was scary over 130, I put the NT05Rs on and the car was perfect. I've never used the M/T tires again. I think the sidewalls are way to soft on the M/Ts
Essentially its Cooper Tire (Mickey) vs Toyo Tire (Nitto).
I think Toyo's OE tires wear like shit (Im sure you remember the ES330 OEM Toyo) but the Structure is great, Still have my original set of NT05R's. I think Ill put them back on sometime.
