Anyone know if we have a way on the 2025s yet to calibrate for bigger tires? My difference from the 245/70r17 stocks to the 37x12.5r18 is going to be insane. Using a calculator it looks like showing 56mph is gonna be actually 68. 40 will be 48 and 30 to 36. Oof. Gonna be a pain eyeballing that speed.
 
Use a nav app on your phone for now I guess. Shift points will be a little off too. Why are they such d-bags about stuff like this? They know people upsize all the time, should be built in.
 
Yeah it's frustrating, bigger fuel tank is like #3 on my upgrade list.
 
I hope someone gets this figured out. I need to get snow rated tires before winter, and I want to go bigger when I do. If and when someone comes out with a bigger gas tank for the non diesel crowd I want one, but not until I can change the tank size for it.
 
Interesting.... dealership here in AZ recalibrated mine. How'd they do it? and I know they did because it matches my phone app speed?
What am i missing? Unless you guys mean do it yourselves?

What size did you get it calibrated to? I thought the dealers could only pick from stock sizes available, so maybe they got you close depending what you're running.

I went from stock 285/60r20 to 35x11.5r20 (pretty much 295/65r20)... So i guess the discrepancy isn't that much of a difference but my speed is accurate across 3 different speed apps on my phone i use for boating. So your maybe right?

That's good to know, I am going to check with my dealer as I am running 35 x12.5r18 and it would be great to get it dialed in. 295/65r20 is 35.1 converted so that should work.
