Steering wheel angle while towing

Given the rarity of this issue, blaming P-metric tires makes ZERO sense. The vast majority of light truck users, and just about everyone down from there, uses passenger tires. Not to mention, no F150's are known to do this, unless there are suspension wear, trailer, or trailer hitch issues. Bottom line, not likely the tires. Could be something amiss in the EPS system, but this all seems odd, because anyone who owns one of these trucks knows they don't tolerate sway, and they don't even tolerate a steering angle that doesn't correlate with the direction of vehicle travel / polar moment.

I agree P metric tires are capable for light duty towing. I would have to disagree with your blanket statement though. And that's because I have plenty of experience with both on the same vehicle. I never had stability issues with my last E rated tires, even at the lowly 35 PSI that I maintained for daily driving, and periodically forgot to increase for towing. 40 to 50 PSI was rock solid. My current P rated tires have a max inflation of 51 PSI and a much higher rating than the rest of the truck suspension, yet yielded terrible towing characteristics at 35 PSI. It's much improved once I inflate to 51 PSI, but still not as solid as the LTs. Granted my old truck could have worn suspension components, but they're not that bad. It's well maintained.
