Low Profile Tires and towing

[bikendan]

From what I remember, when I sold tires, low profile tires have shorter sidewalls, making them weaker.
This is for P rated tires.

IMO, I think the low profile tires ride rougher at 35psi than my truck tires at 45psi.

Isn't low profile and high quality an oxymoron?
As with the previous post, the ride would be terrible. For the towed rig and its contents it would eventually result in disaster. Things will shake loose, break, buckle, etc. You should be trying for a smoother ride, not a rougher one.

Agreed.

Being that your Ford Expedition is a 2008 I doubt it has Original tires! I also doubt that the "Low Pro O-Ring Tires are the same size as Original,so door sticker PSI is out the door! O-Ring tires look good at Car shows but are not your Go TO tire for Towing,the letting air Out when you get there Idea then inflating them before going Home is a Real Deal Breaker! Youroo!!

Spot on! All the vehicle specs for air pressure go out the window when you change tire size. I remember reading in a 4wheeler magazine a number of years back about a conversion factor for air pressure when changing tire sizes, or if it's a size offered in a factory package, it could be researched that way. Either way, low profiles aren't the most tow friendly tires out there.

Another good point here, make sure you at least have LT tires with a suitable load rating for the task.
