Hi folks -- I made an "interesting" discovery today on my brand new 2015 Ford F-450 pickup when I tried to install TPMS sensors.
I have the TM-507RV/SE unit from Truck System Technologies. When I put the sensors on the front tires, the low pressure alarm went off as soon as the sensors synched up with the display unit.
My brand new front tires which are labeled for 110psi were only inflated to 85 psi on one side, and 84 psi on the other.
Also, the rear valve stems were pointed into the space between the dual rear wheels where I think it would take a hobbit to reach them to air them up.
Needless to say I will be making a call on the dealership ASAP, but I wanted to check in with the folks here on the tire inflation -- I'm sure the dealership will try to tell me some BS about underinflating the tires for the ride or something, so I was hoping to get some wisdom from the folks here before I go in to discuss this with them.
Any thoughts?
Thanks & Best Regards,
Mitch
there is a chart you can get that shows tires rating at different pressures.
I always aired down my tires when not towing or carrying load.
They are rated at certain capacity at MAXIMUM 110 psi.
Not necessary to keep them there when empty
Of course I had no TPMS to deal with..:h:h
