Ok I need some info any of you guys/gals can give me. I just recently changed my tires bcus I wasn't getting any traction or handling on them during this winter season. Plus they were getting bald. I went from a 205/50R/15 to a 205/50R/15 and I read that your speedometer may be off?? SO I was wondering if anyone would know how to calculate how much I lost going to a lower radial?? Doing 80 on the freeway seems like i'm only going 70-75mph or doing 25-30mph doesn't seem like the actual speed either.
I got Yokos on them I was supposed to get Toyos ....long story....but regardless the handling and cornering on them is a lot smoother than my old worn out tires. Could it be that I'm just getting used to the new tires? |

Just set your cruise for 60.
When you hit a mile marker, start a stop watch. In exactly 60secs your should pass the next marker. If you don't then use D=T/V to figure your speed. (i think that's the formula)
