Anyone in Tampa, Fl area that is competent to inspect my 7 year old tires?

the distance to stop is calculated: distance = (speed x speed)/ (30 x drag factor) : d = s^2/(30 x f) s = 45 MPH, f= 0.528, d = 127.8 ft. 0.528 g's is the requirement for most heavy rigs, FMCSR PART 393.52 45 MPH is 66 FPS, in 4 seconds, you travel 264 ft. this is the point you must decide to stop or keep going. you have 136.2 feet avaiolable, at 45 MPH, this is 2.06 seconds for reaction time. total time to stop is not relevant, you will be stopping behind the stop line after the light has turned red, no viloation
