Need tire info

I am in need of new tires here in the future and since I have a 2WD DA I want to get a larger tire. I bought a set of the PYO wheels from a guy at work so I will have nicer wheels as I cant afford the aftermarket ones. I want to get at least a 265 size and my sister in law is the office manager of her dads tire store. They sell, Firestone, Cooper, Michelin and I want to find a good riding tire but one that will also be good to tow with as I will be gettting rid of the pop up and buying a 5er in the next yr or so.
Suggestions from those who can help??
