So i have a 15 rc350 Fsport that i purchased with summer tires. Someone plus sized the rears to 275/65/19 and put on Michelin super sports. The car came from Florida so summers were fine for the previous owner. I live in pa so i ordered 2 Goodyear F1 asymmetrics in the stock size 265/35/19. I right away noticed the vehicle doesn’t handle as well or feel as smooth. I somewhat expected it as i knew i was gonna loose some performance for the a/s benefit. What i didn’t expect is that now when I’m taking corners even at a speed of 35mph my trac light will flash. Anyone have any insight into this? I thought i was doing a good thing by putting the stock size on but could the 275’s be better for it? Any advice or insight would be appreciated!

 

Your trac light is turning on when you take turns at 35 mph because 1. youre going 35 mph around a corner and 2. your tires inevitably are going to spin a little bit. Try slowing down your turns. youre going to burn through the edges of those tires driving like that.
