Ksa, thanks for the tire suggestion. I just checked them. They are actually 4 ply extra load tires. That means the recommended inflation is 50 psi. Of course mine are at 30-35 psi. Tomorrow i will go air them up to the proper level. I imagine 15-20 psi could definitely gonna be a problem. I think i remember reading that 1 psi is a 1% lose in economy. Now i don't think i am losing 60% economy, but i am sure there are losses happening.
