"What is MOST important is the PROFILE ! For a truck, I would want at least a 70 series profile tire. Big difference in ride quality."
Says someone who is either being stubborn for the sake of trying to right, or hasn't driven too many newer trucks, or just plain don't understand.
You bring your 265-70-17s over (what was OE on our ole Dodge), heck bring a set of 285s as well and we can compare them to the 60 and 65 series 20" tires I have for the truck currently. $20 says at the same or equivalent pressures, you cannot tell the difference.
There was once a saying....something about an old dog and new tricks. Trying to remember it....dang
