All stock tires are programmed with a 1-2mph variance. This applies to almost every single vehicle on the road. It’s unfortunate.
i absolutely don’t recommend driving without a reprogram if you go from stock 275/65/20 to 275/60/20. My speedometer was 3-4mph off! GPS speed would say 65...

I myself have to do a chalk test too. At 41psi each tire can still hold over 2575 which is plenty...
95% hwy. I run the tires at 41psi and they warm up to about 44psi. I get no TPMs warnings at 41psi.
this was in conserve mode for about 90% of the trip on low ride height. Also on the way home it was raining the entire trip.
50 degree weather. Battery temp avg was 70degrees
55 to 70mph...
I installed my set of LLL and went +4 front and 0 rear and so far so good. Gives a good look in standard right height. Ride quality seems the same as stock but truck does have a better stance.
the front links are such a bitch to remove the stock torx bolt. I’m pretty sure I cursed out the...
