I would say, "Yes," on using light truck tires. I looked into Michelin Defender LTX M+S 225/65R17 tires which are for light trucks? However, they are 225's and not 215's plus are slightly larger diameter than my original ST215/65R17 Kenetica Loadstar tires made my Kenda. Because they are slightly larger in diameter, I'm concerned that they might rub on the metal step that hangs down between the front and rear trailer tires.
