That is a huge misconception.
Bigger does not always equal safer. Modifying does not make it safer either, with exceptions.
Think of this. Your truck in stock form is capable of emergency maneuvers, proper stopping distances, its handling is designed around the factory wheel/tire packages, etc.
37s and a lift? Now you've affected your braking distances, handling and ride control. You've raised your center of gravity higher. Your front visibility is now obstructed more than stock, same for your rear. Does it look cooler? Yes. Does it now work as good as it did from factory on road? NO.
As for my mention of exceptions? Say you had a sedan or crossover. They typically come with all season tires. If you swap out for a performance all season or a summer tire, you improve your car by lowering its stopping distance (better braking because of traction) and improve the handling (regular and emergency) of the vehicle. That is an actually improving modification. My old 2019 LD 1500, I ran UHP all season tires on 20in wheels in a factory offered size. It improved all aspects of how it drove over the Duratracs it came with from the factory in the stock 18" tire.
37's would probably fit with a 3" lift. GM only has two gear ratios for these trucks 3.73 for gas and 3.42 for diesel. And they can't be programmed for anything else at the moment. The rough country module just corrects the speedometer and odometer to adjust for tire size it's not a programming device.
You haven't said if your truck is gas or diesel, but for a gas truck the 10L1000 with 3.73 gears has a lower final drive ratio than the 6L90 it replaced would if it were swapped to 4.10s. GM used the same 3.73 gearing in 6 speed gas trucks. I don't think you'll have any issue running 37's with the 10 speed other than the reduction in mpg and towing/weight capacity which is as much of a function of the lift as the tire size.
Actually, it probably was the brakes. It's weird the way the messages came across, but I took it to the dealer thinking that something was wrong with the sensor and in fact, the rear brakes were shot. What I don't understand is why the messages never said, your brake pads are low. First I got the message I posted above, taking about new pads being detected. Then I got a message saying that the system needed repaired. It never said, change your brake pads.
Did the KYBs keep it the same height in the front? I was concerned that pre-assembled assembly would raise it up an inch to standard non-z60 height.. I guess which it would make the rake 1 inch instead of 2 inches.
