So, my TPMS has been learning for about a week now and it's driving me crazy.
when going through the settings and looking at the manual, I see that for full load the psi should be 36/44. Does anyone actually have experience with that high a psi? I would imagine the car would feel like a riding on rocks.

 

I think the additional weight, in turn, puts additional compression on the tires resulting in a higher PSI - the idea being if the car is loaded, that's the correct PSI for inflation. So you don't inflate to 36/44 and then load the car, rather you load the car 1st, then inflate to the correct pressure.

It is similar to inflating at different temperatures (other than 68F) - my car on the highway reads 37/43 (sometimes more) after the tires heat up.

 

Hmmmm... went for a long family trip today with my psi set at 35.5/44 before everyone got in (wife and two 4 year olds). Actually, I loved the feel of it. I might be crazy but the ride felt softer. Almost like I could feel the suspension working more.

Regardless, The TPMS system read learning for about 30 minutes and then just switched to inactive.

 

Yep once the tires heat up my constant pressure at least from the computer is 36/44. The front cold are like 34-5 and backs like 42, but yep 36/44 is quite the constant for my tires.
