The speedometer calibration is completed through the PCM software update and the TPMS works through the BCM so each system is completely independent of the other.

They will most likely need to use a J-46079 calibration tool for the BCM to recognize each TPM sensors identification to its corresponding wheel position.

Also if you're installing new wheels of a different size you may want to have the front & rear tire pressures recalibrated with GM Tech-2 diagnostic tool.

The EL-50449 or any other TPMS reset tool might work to activate the relearn process to its corresponding wheel position, following the instructions in the pdf document above.

The GM Tech-2 will only calibrate the BCM intended for its lowest pressure point activation used for the TPMS low tire warning message in the cluster display.

I believe it reads the information from the ABS unit to the PCM and send the signal to the BCM for the speedometer reading in the cluster which is all done over a CAN bus line.

There's a couple options to have the speedometer recalibrated:
You could use the GM dealer to have the PCM updated with a new SPS calibration file or you could have (Supermodulation James) or (Lime-Swap Jeremy) perform PCM tune with the updated tire size.

Both sensors operate on the USA 315Mhz radio frequency, so it should work in theory as long as each TPMS device has a good battery with an active transmitting signal.

I would just be concerned with relearn procedure of the BCM to recognize each sensors wheel position process for the system to function properly.

Each sensor has a unique identification code that needs to be relearned into the BCM to its corresponding wheel position and if you're replacing a defective sensor with an aftermarket multi-fit or direct-fit model, it will need to be activated & reprogramed. This can be accomplished while the sensor is removed and inserted directly into the reprogramming device before it's mounted into the wheel or some programming devices will work with the sensor installed depending on the tool brand or type of replacement TPMS.

Here's a video of how to relearn the TPMS wheel positions on a 2010 GMC Canyon without using a reset tool. https://www.youtube.com/watch?v=Qo9HNDKMipk​

There is one minute to match the first tire/wheel position, and five minutes overall to match all four tire/wheel positions. If it takes longer, the matching process stops and must be restarted.​

The TPMS Sensor Matching Procedure:​

1. Set the parking brake.
2. Turn the ignition to ON/RUN with the engine off.
3. Turn the exterior lamp switch from AUTO to OFF four times within three seconds. A double horn chirp will sound and the TPMS low tire warning light starts flashing. The double horn chirp and flashing TPMS warning light indicates the TPMS matching process has started. The TPMS warning light should continue flashing throughout the matching procedure. The LOW TIRE message displays on the Driver Information Center.
4. Start with the driver side front tire.
5. Place the relearn tool against the tire sidewall, near the valve stem. Then press the button to activate the TPMS sensor. A horn chirp confirms that the sensor identification code has been matched to this tire and wheel position.
6. Proceed to the passenger side front tire, and repeat the procedure in Step 5.
7. Proceed to the passenger side rear tire, and repeat the procedure in Step 5.
8. Proceed to the driver side rear tire, and repeat the procedure in Step 5.
9. After hearing the confirming horn chirp for the driver side rear tire, check to see if the TPMS low tire warning light and the Driver Information Center LOW TIRE messages have turned off. If yes, the TPMS sensors have been relearned. Turn the ignition switch to LOCK/OFF. If the low tire warning light and the SERV TPM message on the Driver Information Center are on after completing Step 5 for the driver side rear tire, the sensor relearn process has not been successful. Turn the ignition to LOCK/OFF and repeat the matching process beginning with Step 2.
10. Set all four tires to the recommended air pressure level as indicated on the Tire and Loading Information label.

I'm assuming your truck has the initial two horn beeps in the third step of the procedure but you can't get the BCM to recognize any of the TMPS units with a single horn beep?

The BCM can only recognize TPMS identification codes within a certain number range which may have something to do with the part number. So it's quite possible the sensor would need to be reprogrammed to match the identification code range. Most tire shops just have one brand sensor to offer with the same brand programming tool and finding a shop that has the universal type TPMS programing tool may be difficult.

A universal clone tool such as the TechSmart T55000 may work if you can read the TPMS identification number off the body of the old sensor or the more expensive universal TPMS programming tool such as the ATEQ VT55 can display the old sensors identification number with an external wand type antenna and then transmit that information to the other sensors.

Most universal programmers such as the ATEQ VT55 have the year, make and model ID number arrays stored inside the memory bank so it would have to be entered manually before writing it to each sensor.
