AVEO speedometer calibration;14" vs 15" wheels.

[shiver22]

This is an old thread but i havent seen it anywhere else.

There is an ltx model that is 195/60r15 but they say in places it the lt model vs the ls model that most American cars use 185/60r14.

Gm can refresh if you make it clear you want a stock recalibration. The newer aveo has 215/60r18 but gm might not want to do it.

I changed to 205/45r17 using the 195/60r15.

There is places that say the electronic speedometer can be recalibrated using a procedure by holding the odor button while starting the car and wait until the speedo goes up to half. Then release it and hit it again and it will go to max. You drive 2 miles, then hit the button again when stopped and it will lock in how many pulses it went with the bigger diameter tires. You don't need to take it to gm to do 5his.

Read up on this on Google. I don't endorse this and am in no way responsible if it doesn't work or screws up something. It's your responsibility to choose to do it after researching it and choosing to try.

This is on automates website. Google it. Good luck
