front tires worn out on the edges much more than the rear tires

What is your question?

less than 30000 miles, the front tires were worn out on the edge and both front tires had to be replaced. Tire pressures are maintained at 33 PSI or 32 Psi. Do I need to have toe and camber adjustment? Thank you
