questions about speedo calibration and 2015+ trucks...

[mattydipps]

im not entirely sure where to put this since it hits upon alot of the sub categories so ill just plop this here..

like the title says, im not really financially set to spend the 1100 bucks to tune my truck at the moment and re calibrate for a bigger tire size.. unfortunately, i found a nice gash in the side wall of my passenger front tire and will most likely end up needing a new tire.. (tpms sensor went off today that it was low on air).. instead of spending 250 bucks for a new tire, im heavily considering spending a couple more dollars and getting a set of bigger tires.

now i have two questions,

im not lifted yet.. so is there a bigger tire that i can put on without having to do any pinch weld mods or any kind of modifications to the truck? i wouldnt mind going a touch bigger if i had the room to play with in the wheel wells.

secondly, will the hypertech speedo re-calibrators work with the 2015 and up models ? i know the issue with the tuners taking so long to drop because of the pcm in the truck.. just curious if the speedo re-calibrators have the same issue or not..

275 65 20 will fit no problem. Just realize your speedo will read a little slow. Not sure if the recal tool works on a 2015.

I just put on a level and 275/65 20's and found that my speedo is about 1.5 MPH slow, which is slightly noticible but very minimal. Just FYI.
