You don't need light truck tires. You need tires which are rated for
the load. Tires made for a large Mercedes, for instance, would work
fine.. better, as they will be designed for better grip. LT tires are
NOT performance tires, and will inevitably have lower grip than any
decent car tire.

For this reason I would never fit LT tires to my van. Low-grip tires
can easily kill you.
