Speedometer Help.

Does anyone know where you can get your speedometer adjusted for bigger tires? Also does anybody know what the stock tire size is on an 05 4x4 V6 Tacoma?? I have 305/70/17 Goodyear MT-R's right now which are about equivalent to a 34" tire..

Anyways any input would help alot, i wanna actually know how fast i'm going and how far i'm actually going on a tank of gas. Thanks

 

Come on guys like 30 people have looked at this thread and no replies! there has to be somebody that knows how to fix this.. I can't be the only one with big tires on my tacoma that wants an accurate speedo..

 

i think the scangauge II (the one everyones buying as a group buy) can display accurate speeds. I'm not exactly sure though...i might be wrong...its also supposed to display gas mileage

 

I think the only device they make for Tacomas to recalibrate the speedo is for the 1st generation trucks. Nothing out yet for the 2nd.

 

Try this link bro. It helps
