Calling around today and one Chevy dealership has a few sets on hand pre built with steel rims and tire pressure sensors. They are packaged in a 255/70/17 which he says will not affect the speedometer or the abs/traction systems. They are Michelin Xice Lattitude for $1540.00 + taxes installed.
Yup the 255/ 70R17 are about 1% faster, depending on the tire manufacture O.D. ,at least thats what the Michelin Latitude Ice tire 255/70R17 measure.Carl_NDelta said:It's that time again!
Then I can get a P255/70R17 tire that brings my O.D. of the wheel to exactly the O.D. of my oem P255/65R18's.
I can only comment on my experience with my 08 Enclave. I bought a second set of OEM rims off of the Enclave forum. When I put them on in the fall all I had to do was go through the process called out in the owners manual to have it learn the new sensors. I can swap freely between the two sets just by doing the air in/air out process in the manual. I did not have to go to the dealer. I can not comment on aftermarket sensors if that is what you end up with.Carl_NDelta said:From reading the above I figure that I am going to have to buy TPMS sensors for each wheel in order to keep the pressure monitoring system happy. I'm told that the new sensors will not work with the car’s TPMS until the system is recalibrated to communicate with them. Is this true? Is this something the tire installer can do or am I going to have to visit the dealer? What about when I go back to my OEM tires/rims in the spring - am I going to have to recalibrate again?
I've checked with Costco (Canada) and they claim to have the TPMS sensor from the Acadia for $38 CAD and I can get 17" black steel rims for about $50. Then I can get a P255/70R17 tire that brings my O.D. of the wheel to exactly the O.D. of my oem P255/65R18's.
Have I got this figured through?
