You may need to just drive in those tires for a while to heat cycle then a few times so they smooth out. My spare car sits a lot and the tires feel really odd for a good bit untill I drive it a few days. I just bought and installed them last year so they have very low miles too
Your truck looks good. I am not sure why people are so worried about the gas mileage on a truck that drives and feels like a rally car… on stock wheels and tires if I drove like my grandma, I could squeeze 18.5-19 mpg… but when I am driving spirited and no highway miles I got it to 10.2 mpg…
we all own a very special truck, and with these special trucks, we won’t get what a Miata or a Prius gets in mpg…
