The EEZTire T515 is an aftermarket tire-pressure monitoring system designed for RVs, trailers, tow vehicles, and towed vehicles. It reports pressure and temperature from external sensors, giving the driver an early warning tool—but it cannot determine the correct cold pressure or replace physical tire inspections.
Testing note: RVGearScout has not performed hands-on testing of this product. This review is based on current manufacturer information and RV-specific buying considerations.
Quick verdict
The T515 is worth considering for multi-axle RV combinations that need configurable high- and low-pressure warnings. Its broad sensor capacity can support a motorhome and toad or a truck and trailer, but buyers should map every wheel position and confirm sensor, valve-stem, and repeater requirements first.

How it fits an RV setup
EEZ RV Products describes the system as monitoring pressure and temperature in real time and supporting as many as 26 tires. That capacity matters only if the chosen package includes the required sensors; compare the monitor, sensor type, anti-theft hardware, charger, and repeater contents rather than assuming every listing is identical.
Set baseline pressure from the RV or tire maker’s guidance for the actual loaded axle weights, not from a TPMS default. Program alarm thresholds deliberately and label each wheel position. Metal valve stems may be advisable for heavier external sensors; confirm with a qualified tire professional.
What stands out
- Large combination support: The platform can monitor many wheel positions for motorhome-and-toad or truck-and-trailer setups.
- Pressure and temperature data: Both readings can help flag a developing problem before a visible failure.
- User-set alarms: Owners can configure thresholds around their documented cold-pressure plan.
- Replaceable components: EEZ RV Products lists sensors, repeaters, and monitor parts for the system family.
Limitations and checks
A TPMS reports what its sensors detect; it does not inspect tread, sidewalls, age codes, valve stems, lug torque, wheel bearings, or load capacity. Check every tire cold before departure and stop safely to investigate an alarm. Never continue driving merely because the pressure later appears to recover.
Radio range varies with coach length, metal structure, sensor placement, and interference. A repeater may be needed even when a short driveway test succeeds. Confirm every sensor is assigned correctly after rotation, service, or battery replacement, and do not set thresholds so wide that meaningful warnings disappear.
Who should buy it?
The T515 fits owners with several axles who want one configurable monitor and are willing to document their setup. A simpler four-sensor system may be easier for a small trailer, while internal sensors may be preferable for owners concerned about external sensor weight or theft.
Bottom line
EEZTire’s T515 offers useful scale and configurability, but it becomes a safety tool only after careful pressure research, sensor mapping, and alarm testing.
