Hello I have a 2011 AWD Edge it has p245/50 r20 pirelli outer diameter 29.7" and section with 10.0, I would like to instal GoogYear Fontera tripletred 275/55 r20 outer diameter 31.9 and section with 11.2. The diff is outer diameter 2.2", section with 1.2" Will this work, and will this confuse or mess up the computer system in the car,like traction control,sway control for the trailer tow,the breaking system AWD.Thanks,Emel

 

If all four tires are the same, it should not affect the computer and brakes. It will make your speedometer to be off about 7.4%, using your figures for daimeter. You may have some clearance issues with wider width, are you also considering different wheels? If so pay attention to offset.

 

No the same wheels, 1" higher to the body & 1/2" wider in & out to the fender. Thanks for the info Emel
