Mishmash of info....
Here is clarification
There are classes of tires
P, class are for passenger car and need to be de-reared a min of 9 % when used on trucks. The OEM has already done on half ton...not fake half tons...regulate half tons
Next higher class is LT and no de-rating needed
Their weight ratings are numeric for P class. For LT, letter designators. C represents 6 ply, D = 8ply, E = 10 ply
P class has a very small edge for better ride quality over the same metric sized LT
Noise is more a function of tread type. M/S or AT treads noiser
Via SmartPhone...excuse the fat finger typos!
LTs are noisier and harsher riding. simple
and if you are not loading over your p metrics you don't need them.
