I think you could try drill 3 extra holes in the spare tire rim and have 4 sensors mounted 45 degrees apart and still have 80 PSI in the spare tire.Don't know if you could mount or dismount the tire without breaking a sensor or two. I think you may have been once able to adjust the tire pressure thresholds with a Chinese competitors tool but now guys are bitching since last Chrysler update the tire pressure threshold adjustment function is not accessible. Almost Got to believe the OE , Snappy, and other companies want certain desired functions kept licensed and to Strap-On-ify The Rogue Chinaman to get with the program and Genericify functionality down to a level field and have you and me pay to buy a J box and a OE subscriptions to be able to do this and other important simple OE functions like tire pressure thresholds and change Revs per mile and rear end ratios . Guess with so many ambulance chasers and product liability lawyers ready to pounce, the OE wants to keep non stock modifications out of aftermarket (HillBilly) Shop hands without paying dearly to get the capability, arguing changing settings could ultimately be used to cheat odometers and create safety concerns with ABS and vehicle stability control systems.
