Tire pressures experience

[JRS]

With individual tire weights with a 85% full fresh tank and a full fuel tank I run at 90lbs on all 6 tires in the back and 110lbs on the front. Actually Newmar suggested 85 in the rears and 105 up front but I increased it later figuring I added extra weight since then.
On hot days my steer tire pressures will increase to 129lbs and rears around 110lbs.
On the second visit to the mothership a few months after factory pickup, Newmar will conduct the individual weights for free.

I have been running 90 on the rear and 110 on the front. Temps rise to 125 F and pressure to 130+
The rears temp increase to 115F and pressures go to 104 with the tag axel tire temps run 5 F hotter but pressures only go to 104. This is running in 70 F ambient temps this spring. We will see what happens when we start hitting the mid nineties later this summer. I just want the damn instrument screen to stop the warnings. I am still looking for what I need to program the high and low thresholds.

May have changed but to my knowledge, there's a programming tool you can purchase from Valor to change the settings. Your dealer should also have this tool. I choose to ignore the constant warnings. Not a fan of the Valor system

I had been watching this tread to see if there really was a way to actually change the useless SoartanLync TPMS warnings.

I bought 2x 20k weight scales and do 4 corner each major trip. I do cheat and after chocking other wheels lift the cornet up on the leveling jack 3” off ground and slide the scale under. Use both for rear and tag each side.

The SpartaLync TPMS system is a total PoS. Ours has never been trustworthy. Most trips I am lucky to get 3 or 4 tires to read at once, never the same ones. Totally random. Totally unreliable. Total untrustworthy. This should really be a lawsuit. After 6-8 reprogramming, antenna moves and other attempts our Freightliner Elite Oasis shop just tells me “these never work”. We paid for this junk and now we can pay SpartanLync for a tool to make junk not be so annoying every hour? BS.

FCCC issued a recall for all these issues that was Federally mandated but ignored most of us. It is not just XC chassis also covers M2, SL. Has never been resolved.

TPMS is a DOT Requirement on all vehicles for 10+ years. Some states Require atPMS to be functional at annual inspection

We need to make noise.

Wake up Newmar!! Casey Tubman Stand up for us.
