Our family will be taking delivery on a new Travel Trailer very soon. I have an 2007 Expedition EB regular length with HD tow package. The OEM tires are the Pirelli Scorpion STR A size P255/70/18 112 S. Sidewall shows max psi of 44 and max load at 2,469. We expect the TT to be around 7,500 fully loaded.

Does anyone have first hand experience towing similar weight with this tire that you could share?

I'm sure the best move is to replace my tires with LT tires. However, we only have 16,000 miles on current tires and would of course prefer not to have to replace them just yet.

Thanks in advance for your input.
