To inflate properly, you need to weigh your rig, fully loaded with your toad. Then look up the load vs pressure chart for the make, model and manufacturer of the tires. Then inflate the tires to the chart recommendations, in the morning before the coach has been driven or the sun has heated the tires. Never use the pressure listed on the tire sidewalls. That is the tire's maximum pressure for the maximum load.



After proper inflation, the TPM will be a useful tool for detecting leaks and monitoring temperature.

That is totally unnecessary. Just use max tire pressure (sidewall). Absolutely nothing wrong with that and eliminates the useless calculations.

Doing it your way is risky. Your always going to be at max weight for the tires. Just air up to max and call it a day.

Remember, (in case you didn't notice) you're in a motorhome forum and their tire recommendations are different than for trailers.

Over inflating tires will give you a hard ride and wear the center of the tires. Underinflating will wear the edges and heat the tires. All tire experts and Freightliner recommend inflating in accordance to the load.

With my Michelin XZE2 75/80R22.5 tires, I would be crazy to inflate the rear dually to its maximum 110 psi. My load calls for 84 psi. That's why I have 45k on them and the tread looks like new. Although many of us might have the same model of Berkshire, we all load it differently.

That could be why I see more towables on side of road changing flats. I can't recall the last time I've seen a class A on the side for the same reason.

The reason you see towables on the road is the crap ST tires they use. Your RV's have decent tires.

To the reminders about being in an RV forum... yes and thanks. I wasn't thinking about that.

To change the subject back to the original question of a good TPMS. Does any one know if the EEZ T515 is compatible with Nitrogen filled tires?

I own the EEZ RV TPMS and love it. I have nitrogen in my toad tires and it works fine. No repeater needed for my set up.

I just purchased the Tire Tracker 500 system. For a 10 tire setup cost $450 but it has lifetime warranty, nice display, documentation and replaceable batteries. Installed on coach and toad but have not been on trip yet. Will advise after we do.

When that didn't help, they then said to move the sensor to another wheel. When that didn't help either, they agreed to send me another sensor. My system is only a little over 2 years old.
Yes, but they also made me unscrew the valve stem a little to. They wanted to make sure it was making good contact. That was after I told them I even changed the battery already....But I got a new one in 2 days....

The TST 507 seems to be the most common choice. Same choice we just made as well. We bought the Flow through Sensors for convenience. The internal were an option and in retrospect I probably should have sprung for the extra coin.

Whether you buy the non-Flow Through or the Flow Through, INSURE you tighten them fully prior to setting them in place. I learned this the hard way when one tire kept losing pressure and it was a loose sensor on the valve stem.

Good Luck!

I am on the Technorv site and don't see any mention of flow thru vs non-flow thru.

Also, is there any difference in function between the 507 and 510 systems other than user-replaceable batteries, or not?

507 is the newer system with replaceable batteries. You want replaceable batteries.

a quote about the 507 found on the 1st. link below:

"This system works exactly the same as the 510RV but it has USER REPLACEABLE BATTERIES in the sensors!"

I have the TST507 and it works great. The 507 is actually the newer model, replacing the 510.
