speed recalibration ???

[chevykiller]

my old tires were 205's and my new ones are 245's what kind of differences in my speed will I have???

that's gonna depend on the ratio.

what are the full measurements of your tires? The second and third numbers are as important as the first for this.

what size were your old tires?

205/65/15

Your fine with those tires.

Your speedo is only 0.9% slow with those tires.

So when your Speedometer reads 60 your really going 60.5

Basicly no difference
