ive got 235/45/17 kuhmo 712's(brand new) on now, or should i run my dunlop sp4000(half worn) stock size, which will have better results to save me time once i go out next week?

 

i had SP4000's, and i now have kumho 235 45 17's. if you're runnin stock size tires anyway, you mnight as well run your wide ones. i'm assuming for autox or drag right? anyway, i have 205 55 15's i run at autox but they're SP5000's W rated. . . alot stiffer sidewall than the SP4000's which i believe are only h rated. . .

 

For drags I would run the stockers, and gett em good-n hot.
