Happy 1year owner of a 40,000 miles ‘15 XKR ‘vertible. Despite the quirks. One quirk is the lame factory TPMS system. I want more than a warning that a tire is dangerously low. I want to know if I’ve got a slow leak, which the factory system won’t warn you about, so, I installed FOBO Tire 2 system. This has the little caps installed on the valve stems, that connect to a little repeater via blue tooth, which then connects to a phone app via WiFi. And the app is CarPlay compatible. You can read instantaneous pressure & temperature, and set alerts. I have alerts set for 6 pounds less than recommended set points.

A few days ago as I was lounging in my recliner, my phone FOBO alert went off and told me my right rear tire had gone to 30#. I confirmed with an actual tire gauge…topped off the pressure to 36# and went to my tire store. They found a broken off nail in a repairable area, removed the tire, and did a proper repair.

I don’t know about you all, but I don’t have the patience to go around the car before every trip to check tire pressure, I like the modern convenience of checking with my phone. I’ve also installed this system on a recently bought new Honda CRV Hybrid that also has a lane “you’re about to die” TPMS system.

One thing that surprised me about reading absolute pressure is how much the tire temperature can increase when the car is parked and the sun hits a tire. Ambient can be 75 degrees, which is what the tires in the shade read. Yet, a tire in the sun can be 105 degrees.
