I have a 2020 High Country K1500 with the 3.0 diesel. I want to change the 275/50R 22 tires out to 275/55 R22 for better snow/water traction and hopefully a little taller side wall will give a better ride. My question is will the taller tire cause any problems with speedometer readings, issues with ABS/traction/cruise control or any other potential issues?

That's about 1 inch difference. No big deal. Speedo will be off a couple of MPH.

Actually I come up with a little over 1/2 an inch (275 x .05) since the tire aspect ratio is 55% compared to the stock 50%. A 5% difference. That comes to 13.75 mm, which is about .54 inches. I put on tires about 1/3” taller on my truck and it made no difference.

I do know that some vehicles are super sensitive to the wheel speed sensors compared to the engine and transmission speeds. Depending upon the software in your vehicle systems, you might get ABS codes because the computer will see the wheels spinning slower than the computer expects to see them spin.

There are also parameters in the transmission that calculate slip and may also be an issue.

Drive it and see. If you have issues, your dealer can calibrate for larger tires.

People fear change because it threatens what they know, or what they claim to know.

If you really want a better ride, switch to the 18 inch tires and wheels that come on a LT Z71. I have had two of these trucks and have a great ride. The more rubber the better the ride.
