If I get bigger tires will it mess with my Stabilitrac?

Question

My 06 Chevy Express 3500 has Stabilitrac and I'm wondering if I get bigger tires and nicer rims will it mess it up? I keep getting conflicting answers.

Answer 1

Why don't you check with your dealership to see what they think. They are trained for your vehicle, you don't know what sort of training anyone here has (no offence to anyone). They will be able to tell you what kind of tires you can and cannot put on. You don't have to actually buy the tires there.

Answer 2

Oh goody! I get to talk about a SUV. Otherwise known as the: S
UICIDE
VEHICLE ("S" "U"ICIDE "V"EHICLE)

No one has yet had the balls to go on TV and publicly say that the tire size "issued" witht he car from the factory is the only "safe" tire for that particular make and model. While slight variations don't make too much safety differences there is in fact a whole lot of engineering taken into consideration and the main factor is weight and all driving conditions for that tire. Ice, snow, rain, dry pavement, cornering, braking, swerving.

In a perfect world, cars don't flip over from "correcting" a vehicle while you are doing three things other than driving.

Rule number one: all vehicle safety features, everything, is based on speeds between 35-45 MPH. Period. If you want to be safer at higher speeds, buy a NASCAR with a full steel cage and don't bump draft the cars in front of you on the Interstate.

When you do something as simple as change the size of the tire on your vehicle you eliminate the engineered safety parameters. Your speedometer will also have to be recalibrated. And, last but not least, you increase the odds of a high speed manuever roll over.

If you like "big tires" then buy a set of wheels to go with them and keep the originals as is and use them (the originals) in the worse than average weather months.

Low profile tires are very bad for causing roll overs. Rather than a rubber tire sliding over concrete or asphalt you have a steel or metal rim diggin into the road surface and flip, bang boom, a simple slide becomes and near fatal accident even at lower speeds.

I can go on and on but I hope that this gives you some idea as to why you have a specific tire on the vehicle when it rolls off the assembly line.

The manufacturer might offer some tire size variations for your vehicle that they deem as "acceptable". (Not necessarily "safe")
