I got an awesome deal on some 20” takeoffs from a 2020 gmc truck and I put them on my 2008 Tahoe. They look awesome and fit good, but the tire pressure sensors will not mate up to it’s computer. I’ve tried the procedure for the 2008 and that didn’t work. I also tried using the TPS tool and had no luck. Don’t want to break down new tires and wheels, so do I have any more options ?

Get one of those TPMS delete boxes that's talked about in another thread a while back. I think it costs about $100, plugs into 12v for power and gives a fake TPMS signal so you don't need the actual sensors in the wheels.

Nope, can't turn the TPMS system off, it's like a federally mandated safety device.
Here's a link to that emulator site

Can’t turn it off but any tire store can install new sensors by just letting the air out and breaking the beads.
Edit: or you can do it yourself. Put your tire under the back bumper and use your jack to break the bead.

The reason the tire pressure sensors are not mating up is because the sensors on the 2020 wheels are on a different transmitting frequency than what your 2008 uses. You need the sensors for the 2008 model year for them to properly link up to your truck.

So I got the TPMS sensors alarm turned off and it didn’t cost a dime. I pulled out in the driveway and pulled my 2012 Sierra out there with the Tahoe. I put the Tahoe in tire learning mode and pulled the Sierra next to Tahoe and started letting air out of Sierra tires one at a time ( moving the Sierra around to different tire locations letting air out at each tire) and what do you know IT WORKED. Now the light is off and will never come on because the pressure was read from the Sierra and the 2020 sensors will not send signal to 2008 computer...
It checks for a signal from time to time and if it doesn’t get one, guess what? The light comes back on. It’s the same as the batteries in your sensors going dead.
