your speedo is 3.25% faster with the si wheels.

3.25% faster with Si wheels and 195/55/15 tire, so that will add 325 miles more on my speedometer, if I drive 1000 miles on stock 185/70/14 tire right?

thanks

so should i get 205-60-15 instaed of 195-55-15. Cuz i checked that 205-60-15 in Tire Calc reading 1.94% too slow, and that 195-55-15 3.25% faster.

so which tire spec you think is good for speedometer....

thanks
