Sure. You can adjust the tire pressures up 2-3 PSI from the recommended pressures to see if it helps with tire wear. But don’t rule out that the tires are leaking air or that the front end is out of alignment causing the tire wear. Also, the Chrysler mini-vans are little front heavy along with a high center of gravity. This can cause tire scrubbing while cornering causing the outside tread of the tires to wear faster.
