I was told a few things that I thought was bull but just nodded and agreed. 1. tire pressure monitoring is a federal requirement? 2. after market tires or wheels will cause the light to come on? 3. fix a flat will destroy the sensors?

As for the other statement....Pure Bull . Truck-On.... Gold 05,SE,KC 6-spd 4x4

Not sure what year it goes into or went into affect. It came from the Firestone tire problems a few years back. Mike '05 Electric Blue Nismo CC 4X4 My Truck and stuff

And for future reference since I couldn't find it in my owners manual, tire sealant will apparently destroy a sensor.

The service manual indicates that they trigger at pressures below 28 PSI. So I when I had my truck filled to standard 35 PSI.....especially in the winter they would go off all the time. There are so many factors that conspire against you when you have your tires right at 35 PSI. 1.) Your Tire Pressure Sensor might not be totally accurate. It might be actually tripping at higher then 28 PSI 2.) Your tire pressure tester might not be totally accurate. It might be off...maybe too low for example. 3.) The Atmospheric conditions effect your tire pressure. Elevation and temperature effect the pressure of the tire. I have set mine to 40 PSI and have never had any issue with them since. Before I thought I was doing something wrong. But this forum is witness to many people, who have born the same cross with TPMS.

Reply Quote More My Recent Posts Message Me Connection Blocking Invite Ignore User's Posts	About your original #2...aftermarket wheels and tires will mess up the TPMS and cause the light to come on. That right there depends on the wheel you use. The explanation I got from the dealer mechanic, great guy and experienced Nissan tech, is that some wheels place the sensors in a location that makes it more difficult for them to accurately trasmit a signal to the TPMS mounted on the truck. That sets the light off. 05 Radiant Silver Crew Cab LE Performance: Magnaflow Catback\|Stillen CAI\|Autometer DPIC & Voltmeter\|WRP Underdrive Pulley\|Stillen Rotors & Pads Exterior: 20" AR RT-S Wheels\|Nitto 420S\|FX45 HID Retrofit\|Painted Bumper & Grill\|Grillcraft Inserts\|Extang Lo-Pro\|20% Tint\|Quicklift Struts\|Carbon Fiber and Red Striping\|XPEL Lens Protection Interior: Custom 2tone Leather\|Custom Subbox\|Eclipse Head/PPI Amp/Kenwood Speakers/JL Sub\|Sound Deadened Cab\|Pathfinder Switchplates\|VIPER 3000\|DIN-sized Dual Gauge Panel\|Autovation Pedals and Sills

That is why the owners manual tell you to inform your tire tech about them when you put new tires on. I had a set of Revo A/T's put on a couple months ago and told the guy to be careful taking the tire off the rim, and DO NOT touch the valve stems. So far...no problems. If you install aftermarket rims, the only way to keep the TPMS active is to swap the original valve stems to the new rims.

Before I thought I was doing something wrong. But this forum is witness to many people, who have born the same cross with TPMS. If you're running a tire that's rated at 35 PSI max (the number on the sidewall) at 40 PSI it's as bad for it as running it 5 PSI underinflated. If the sidewall rating is higher then you're okay, but if they're rated at 35 PSI like most light truck tires then you're risking catastrophic failure. I'd rather deal with the TPMS light than have a tire blow at 75mph. J '03 SVE KC 4X4 5spd, granite, K&N dropin, foglights, Bilstein shocks, UTR bedliner, microfilter

I'd rather deal with the TPMS light than have a tire blow at 75mph. I don't doubt greater then the sidewall spec is bad. Preach on there. This is my ignorance. The General Grabber AW that were the OEM tires for the 2005 model year, their Max inflation pressure is 44PSI. The Firestone Destination ATs I have now are also 44 PSI Max. Since the 2006 Model year Nissan Switched to the BFG Radial LongTrail T/A and its Max is only 35 PSI. So 40 PSI isn't going to kill me but those have those Long Trails, you guys are hosed, and going to have to deal with the TPMS until you just remove the TPMS sensors, or replace them with better tire that can handle more inflation pressure. 2005 KC SE 4x4 6spd.
