I bought these after reading reviews to use on my 19" T Sportline TSS wheels. Initially they didn't get in touch even after the old bikes were returned home and I rode 40 miles. I ended up getting a TPMS warning. When I got home I restarted the MCU (pressing both scroll wheels). On the next ride, TPMS checked in and a display appeared to select a new wheel configuration. I have asked the tire center to inflate to 44psi and all 4 tires are reading 42psi today. I'll check it with my meter.
