I'm doing the same for my 'burb. I have Duellers on all four, and they've been good tires, but they are not well suited to heavy loads on the rear axle. I'm considering jumping to tires with an E load-rating. With the Duellers, if I push the air pressure to the 44psi max before I tow, it does nicely. But I think I can get a little more stability from the tire and I don't want to feel like I'm pushing the rubber to it's max.
Anyone know if the stock 1500 series rims would have a problem with the increased PSI needed for E rated tires?
