So the POS Goodyear eagle touring tires that came standard on my GT-Line Turbo have a speed index rating of v which is 149 an hour. But they're a touring tire, so they're not very sticky. They test out at about 0.85 g's grip.The thing was built in South Korea. The tires were made in So. Korea. I'm guessing the tires are rated up to 80 mph. (New) Put 12,000 miles on them (who knows) Going fast is fun = With the right equipment............ just sayin
On all the other Gen 3 Souls Kia is using the Hankook Ventus S1 Noble 2 performance tire. It tests out of the respectable 0.91 g's grip. Also rated to speed index of v or 149 mph. Another big difference between the Goodyear and the Hankook is the Goodyears are only rated for about 20,000 mi the Hankook is rated for about 50,000 miles. So yeah, just saying...
