Goldbullet Member 883 Member For: 19y 8m 20d Location: Frankston Posted 06/06/05 10:13 AM Share Posted 06/06/05 10:13 AM Would just like someone to give me an answer to the following, just got some new AMG 19" wheels today anyway had a VN wanting to have some fun at the lights tonight so like a good Ford man I obliged, waste of petrol wasnt a contest.But what I noticed was when I looked at the speedo I was doing 130klm sure didnt feel like it felt like about 120klm. Does anyone know if bigger wheels make a difference to your speedo reading and if so how do you get it corrected.Dave. Link to comment Share on other sites More sharing options...

Posted 06/06/05 10:51 AM Share Posted 06/06/05 10:51 AM I've found that with the factory 17's the speedo reads under, 97/100. With the 19's (275/35/19) its 100-101/100. Hope this helps.Geea.
