odometer counting to fast

[Bully.207]

Any one else noticed this?

I have a 2016 chevy silverado ltz 6.2 liter with factory 275/55/20 with 1500 miles on the truck notice speedo off 1.5 mph did a measured mile and the truck was 270 feet short of a mile so every 19.5 miles i gain a fictional mile and by the way this is a leased truck. Anyone else noticed this? check your odometers. Going to dealer sat i will let you know how i make out.

How are you verifying the information?

 

Well what did the dealer say yesterday?

[Bully.207]

I know Honda and Nissan have had class action suits filed against them for this same thing you know just saying

by a measured mile

[Bully.207]

dealer will check it out 4/9

I believe all the GM trucks are calibrated to the 265/65/18 diameter.

 

So the 275/55/20 will be slightly off as well as the 265/70/17.

Hope this is the case a simple fix would be nice for once

This would affect a sh!tload of vehicles. I'm going to test mine. I too have the 275/55/20. We had the Honda where they were forced to increase the warranties. I don't believe the odometer issue was an accident with the Hondas.

265 vs 275 are the width of the tires. That wouldn't affect the speedometer, the height would.

Mine truck is definitely like this.

 

Run a trip meter on a GPS and compare.

Yup, the 65 vs 55 is the height which is what will affect the speedometer.
