I wouldn't worry about it if it is a new vehicle with new truck tires. I don't mean not to check them occasionally, but chances are they will be ok. I can still remember the days when TPMS was a dream of some congressman.
I have TSTs on my trailer and they work (had the tireminder system but it failed the first trip)
Here's the requirements...
49 CFR Part 571
Tire Pressure Monitoring Final Rule
. Vehicles Covered
The agency proposed to require TPMSs on passenger cars, multipurpose passenger vehicles, trucks, and buses with a GVWR of 4,536 kilograms (10,000 pounds) or less. The agency did not propose to require TPMSs on motorcycles, trailers, or low speed vehicles, or on medium (10,001 -- 26,000 pounds GVWR) vehicles, or heavy (greater than 26,000 pounds GVWR) vehicles for reasons explained in the NPRM.
The Alliance recommended that the agency limit the applicability of the standard to these types of vehicles to those having a GVWR of 3,856 kilograms (8,500 pounds or less). The Alliance stated that the majority of vehicles above 8,500 pounds GVWR are used commercially. The Alliance argued that those vehicles are maintained on a regular basis and do not need a TPMS to assist in maintaining proper inflation pressure in the vehicles' tires.
The Alliance also recommended that the agency explicitly exclude incomplete vehicles, i.e., vehicles that are built in more than one stage, from the standard. Normally, the first-stage vehicle manufacturer is responsible for certifying that all vehicle systems that are not directly modified by subsequent-stage manufacturers meet all Federal motor vehicle safety standards. The Alliance stated that in the case of direct TPMSs, the first-stage manufacturer will be unable to guarantee that, even if physically undisturbed, a non-defective TPMS will function as designed after vehicle modifications (such as adding metal hardware to the vehicle or lengthening its wheelbase) are made by subsequent-stage manufacturers.
Advocates recommended that the agency expand the application of the standard to include medium (10,001 -- 26,000 pounds GVWR) and heavy (over 26,000 pounds) trucks and buses. Advocates stated that tire under-inflation is a pervasive problem with these vehicles, especially given the high percentage of these vehicles that are equipped with re-treaded tires.
