Where do I go to get my spedo recalibrated?

Story:
Last night got rid of my 17'' stock rims and got me some nice gunmetal 18s . my spedo is now off when i go
35--38
40--44
50--55
65--72


and how much would it cost to get recalibrated?

 

prob gotta do it at a dealership, did you increase the total size of rim+tire????

if you stick with the same overall diameter, it wont change your speedo

 

IDK i just swapped rims

 

What size tires do you have on the 18's? Let us know. You may want to consider getting different tires rather than recalibrating your speedo...can do either, but if you go back to a proper size tire in the future, you'll just have to re-calibrate again.

 

Not sure a dealer can fix that.

 

well i checked my speeds wit a gps and its only off by 1-2.. my buddies car is way off lol
thanks for the help

 

Pics or your a dam liar!!!of the wheelz of course

 

i went from 15-17 and mines off too but i just dont care

 

im pretty sure you can change the tire/wheel diameter for the speedo it in HPT

 

Yup^^^

$100 for HPT tune or $80 for a dealer reflash.
