CDN SuperCrew,
Just wanted to let you know that when you make the change in tires, you can have your ECU reset to the proper tire inflation for the load carrying capacity and handling that would be OE the heavier tires.
This will make sure your TPMS is working accurately and within the standard 25% drop in pressure that illuminates a dashboard light for safety.
One of the common tools found in automotive shops across the U.S. and Canada that is fully capable of this is the Bartec TPMS Scan Tool.
I am not from or affiliated with Bartec but own one due to my profession.
It is a quick OBD II hook-up that allows you to make this change with a few short tool clicks. It has very defined rules within it so you are unable to make it what you want, rather to the tire designation based upon your year/make/model (as decoded by the VIN). 10 minutes is all it should take.
Also suggest having that service facility update the placard on the driver door as well with an approved sticker which they likely have.
Good luck!
