The TPMS sensors I purchased from Amazon only made it 4 years on my summer tires. I decided to run the the summer tires for one more year so I loaded up the the tires and took them to my Indy tire shop to mount a new set of sensors. He has a tire machine and prefers to take the tires right off the rims, carefully marking the position of the weights. I’ll just run the tires one more year and buy a new set next summer, God willing. When I buy the new tires, I’ll take a chance with the sensors I’m currently getting installed. It’s a 2008 3/4 ton Suburban with LT type tires. The next thing is my yearly task of pulling off the winters and putting on the summers. We’re in the mountains so I run full-on winter tires. The new sensors are shown. Hopefully they’re better than the last set I had installed four years ago.
