Fuel mileage hit with new drive tires

Wisconsin would still be on a blend also. It makes a big difference, along wit wind and cold air. Cold air is denser and takes more power to push thru it.

 

Don’t fret too much.

I closely research and track tire wear/ purchase. You need to give it 100k miles and closely track MPG over a year to get a better perspective.

Keep them inflated 110 PSI, rotate at 50k, keep the rocks out of them. You’ll be right.

 

Losing 1 mpg is perfectly normal with brand new deep tread 30/32's or 32/32's tires. I've seen it happen before with my own truck. It will get better over time but it will take a long time. Anymore you're better off buying these newer fuel efficient tires that only have about 26/32's tread depth when new for highway units. From what a distributor told me they last about as long as the older deep treads and they most certainly get better mpg's.

 

the wind has been pretty relentless lately too.

 

spring weather is moving in,and the winter winds will subside. you'll see the mileage creep back up.
