New Tires

[KevinKeister]

I just put 35s on my Mojave, do I need to take it to the dealership to have it recalibrated? Thank you!

Or a tazer or similar device to update the speedo and trans shift pattern

No. Buy this.

If I didn't do anything could it damage my vehicle? If I updated the tire size would that take care of the trans shift pattern or is that a separate update? Thank you for your help.

Short term, no. Long term, possibly.

Updating the tire size would correct both the speedometer error and also the transmission shift programing at the same time.

The device @Lunentucker mentioned is probably the easiest if you are not tech savy and do not want to deal with other bypass cables. In theory, the dealership can do it for you but at a way higher cost of close to $300 plus for their minimum labor hour and their access cost to program from MOPAR if they are willing to do it at all. .
