There are classes of tires and then there are load ratings to tires
The below confuses the two different things or attributes of tires...
Lowest class to highest class of tires:
- ST class, or speciality trailer tires
- P class, or passenger tires
- LT class, or light truck tires
- Commercial class, or semi's
- Off Road class and are those humongo tires with diameters measured in feet
Load rating of a tire has either a numeric and/or letter designation...like
the 'E' referenced below...which is most likely referring a LT class tire
Any of the various tire OEMs has a info page to help decipher all this
and here is a good one:
Tirerack.com Tire Specs Explained Tirerack.com Load Range / Ply Rating IdentificationTirerack.com Tire Specs Explained: Maximum LoadThere are more pages, but this should address the topic at hand...add
that "P" class on light trucks (pickups) must be de-rated a min of 9%
of sidewall listed max load rating. Mainly because they are designed
for 'ride quality'...AKA soft cushy ride and not stiff sidewalls for
hauling/towing heavy...why many switch to the next higher class 'LT' for
their half tons, which comes from the factory with 'P' class tires

I am. I have the E rated version. They definitely help with the weight and are better through the corners. I would skip the LT version and go with E.
