Does any have these tires: 265/70R 19.5 low profile

I recently purchased a 2011 Ford F450 dually. The previous owner had customer rims and wheels put on the truck (Bridgestone 265/70R 1935 low profile). I am having difficulty getting specific information about the tires and there ratings. Some of the questions I have are:
What kind of mileage should I get out of the tires?
When not towing what psi should I run in the tires?
When I do start towing 5th wheel what psi should I run?
What is the life I should get out of the 60K-90K?

Let me know if you have any information about these tires.

Don't know a whole lot about this, and pardon if I'm wrong, but I've heard that 80 psi is generally pretty good for towing. Not sure about on low profiles, but it improves handling and gas mileage. Don't quote me on that; someone else on here probably knows a whole lot more than I do and can help you out. Good luck, Bob!

 

Can't help you, but I really gotta ask what made you join TW to ask a question about low profile tires on your Ford? Might be best asked in a Ford forum since not many Tacoma owners are pulling 5th wheels.
