Has anyone run 30 sidewall all around?
I'm looking at new rims and tires for sale,
The tire sizes are 285-30-20 and 315-30-20 I've had 30 sidewall on the front with a 40 sidewall in the back and stabilitrack put me in limp mode every time I drove it. I wonder, considering sidewall is 30 all around if stabilitrack will allow it. Dealer will not reprogram as well as tire shops in town who have the ability to do so won't either because it was unapproved sizes. Thank you guys in advance. |

Also, OEM sizing on ZL1 and SS 1LE is 285/30/20 and 305/30/20. So plenty people are running "30 sidewall all around". |

What do you mean by "won't program them?"

Ok that's good to hear from all of you.
So the dealer will not program any diameter difference because reasons. As soon as I went back to stock sizes tmps limp mode went away. So I've been more cautious about it . Thank you guys for everything! |

I run 245/40/20 27.7" and 305/35/20 28.4" with no issues. You have to keep the front and rear under 1" in height difference. Been this way for 20 years with GM ABS/TCS/Stabilitrak systems.

Given how easy it is to do, I guess the question is: why NOT relocate the harness?

Nice!
Questions: Did you have to relocate the rear harness? What width rims are you using? Are you using spacers up front? Would you be able to go 305 up front with no issues at 20"?
