I just put on 17's Baby

[JDog18]

Howdy..
I have a question..I just put on my 17's Momo Twins..I will get pictures on my site by this weekend hopefully so there not up yet. But i was thinking and since my tire's are bigger isn't the bigger tire changing the speed of my car. After talking i am actually going faster than before but how do i fix it so that my speedometer is correct with my speed again. Is there a chip thing or do i just need to move the dial?

Thanks

what size are your tires? are you sure they're bigger?

If they are, then yes, you'll be going faster than the speedo indicates. There's really no way to correct it. Assuming you haven't gone radically bigger, the diff is negligible...in fact, your speedo is probably closer to right...most read too fast with oem wheels/tires.
