Let's see: P metric tires with flexible sidewalls... Great for rock climbing, hitting potholes and "airing down for sand"... Not so great for stability when towing. So....

The come in Standard load, Extra Load and can be "aired up to 51PSI". That makes the "flexible sidewalls a bit less flexible" but won't stop the sidewalls from "rolling with trailer sway"... So.....

When compared to a LT tire, they're going to be "more squishy" and the trailer lateral movement is going to be "felt more in the seat of your pants"... So....

As with most "anything in these times of highly specialized products" tires are "also selective for the specific task"... With P metric tires, towing isn't high on the list of plusses....So....
