Vehicle: 99' Crown Victoria Police, 16" Rims, 3.55 axle ratio.
P225/60/16
I have owned these tires for about 1 year and 6500 miles. I have a measured reduction in fuel economy with these tires. At 44PSI I get high 19MPG highway. On my old Goodyear Viva 2's which are basically a walmart tire, I was always getting high 22 MPG or more. Those tires had 3/32 tread left and were pretty much shot, whereas these new assurance have 10/32 now.
So why is there this much loss of fuel economy?
I am not imagining it. I can put my snow tires on and still get good mileage (21/22MPG) but I don't want to wear them out.
