This may have already been posted and is likely a newbie type question, but hey I am new to the tire & wheel scene.

On my Sunfire i currently have the stock 15's, I want to go 16's or 17's but i was wondering how much this would affect my speedo?

Is there any easy to adjust the speedometer to get an accurate reading? or is it necessary.. Any help or information would be greatly appreciated


Thanks Everyone

Just get the right size tires and read the faq, you will be fine.

read the faq's at the top. if you dont change the overall diameter of the wheel and tire, then your speedo will be fine (ie. bigger rims = smaller tires)
