Max Tire Pressure Monitoring Systems

MAX SENSOR GEN2

The Purple Sensor

What is TPMS?

The late 1990’s saw a high rate of fatal accidents caused by a drop in the pressure of certain tires. These incidents led to the signing of the TREAD (Transportation Recall Enhancement and Documentation) Act in 2000 to increase consumer safety on the road.

The legislation mandates all light motor vehicles under 10,000 lbs. to be equipped with TPMS technology.

"TPMS" stands for Tire Pressure Monitoring Systems and has a significant impact on vehicle safety.
They exist for the purpose of warning a driver when the air pressure in any of their tires are significantly under-inflated, creating unsafe driving conditions.

The TPMS low tire pressure indicator is a yellow symbol that illuminates on the dashboard instrument panel in the shape of a tire cross-section (that resembles a horseshoe ) with an exclamation point.

Not every TPMS works the same way. TPMS are integrated assemblies that include sensors in the tire stems (Direct) or on the vehicle brakes (Indirect). The illumination of the low tire pressure indicator represents the final step in the process of either an Indirect TPMS or a Direct TPMS.

Direct TPMS

Direct TPMS uses sensors within each tire that monitor specific pressure levels – not just wheel revolution data from the ABS.

To do this, pressure detectors are fitted on the part of the stem that sits inside the tire. Those pressure detectors each have their own battery and transmitter which relay information to the car's main computer.

Sensors in a direct TPMS may even provide tire temperature readings.

The Direct TPMS give

  • Actual tire pressure readings
  • More accurate than indirect TPMS
  • No need to reset after tire rotation and  inflation

Indirect TPMS

An indirect TPMS typically uses the anti-lock brake system’s (ABS) speed sensors as reference. The ABS Sensor measures the rate of revolution of each wheel and can be used by on-board systems to compare each wheels rotation rate.

Based on the rate of revolution of each wheel, the computer can interpret the relative size of the tires on your vehicle. When a wheel starts spinning faster than expected, the computer calculates that the tire is underinflated and alerts the driver accordingly.

An indirect TPMS DOES NOT actually measure tire pressure.
Instead, it simply measures how fast your tires are rotating and sends signals to the computer that will actuate the indicator light when something in the rotation seems amiss.

MAX SENSOR GEN 2

  • IMPROVED SIGNAL STRENGTH - Amplified antenna strength doubles the signal output on our sensors. This makes it easier and faster to read & program sensors through tires of all sizes and thicknessWirelessly reads & programs sensors through tires up to 40” in diameter
  • Wirelessly reads & programs sensors through tires up to a 12-ply F-rating. F-rated tires are an issue for both OEM and aftermarket TPMS. MAX GEN2 signal strength exceeds OEM
  • IMPROVED SIZE – This is the smallest sensor we’ve ever made - 40% smaller
  • IMPROVED WEIGHT – This is the lightest sensor we’ve ever made - 80% lighter
  • IMPROVED VEHICLE COVERAGE – We have more coverage than ever before - 98.5% od veicle are compatible
  • IMPROVED PROGRAMMING TIME - GEN2 Sensors program up to 3x faster
  • IMPROVED CONSISTENCY & RELIABILITY – GEN2 sensors are the most reliable sensors on the markert

FAQ

How do I program those sensors?
You don't have to program it yourself. We will send you the programmed TPMS directly to your home based on your car model.
In some cases we may need some more information about your veichle. If this happens, our Customer Service will contact you directly.
Why do I have TPMS in my Vehicle?
As of 2007, the United States Department Of Transportation (through NHTSA) requires an installation of a Tire Pressure Monitoring System to all new passenger cars, multipurpose passenger vehicles, trucks, and buses that have a gross vehicle weight rating of 10,000 lbs. or less (except those vehicles with dual wheels on an axle).
How offten I have to change the TPMS?
If your see the Warning Light that keeps coming on, it means that part of the TPMS system has malfunctioned. The sensor failure may be a dead battery (in the unit), damage, or failure from natural wear and tear. Our sensors are rated to last 5 years. We suggest to change all four TPMS after 4 years.
Can the battery be replaced?
NO the battery cannot be replaced. If your sensor stops working, you have to buy a new one.
I have changed all my wheels, can I use the old OEM sensors?
If you decide to re-use existing sensors, not only must you pay to have your new tires dismounted, remounted, and balanced, you lose the use of the sensors in your existing wheels if you plan to keep them.
There is also a high risk of damage when transferring TPMS from your factory wheels to your new aftermarket wheels.
It is less expensive in the long run, and much more convenient, to install new sensors when the new wheels and tires are mounted and balanced.
Why a Rubber Valve instead of Metal one?
The rubber valve is more ductile and lasts longer against atmospheric agents, especially in humid places, where it often snows or salty air is present which causes rust.
They are also simpler and more convenient to install and have no loss of performance. If you want to buy metal TPMS, please contact our Customer Service.
