If all those warnings are happening simultaneously I would check the battery. Low voltage can adversely affect the various vehicle modules and computers.
No rubbing issues in entry exit mode in over 30k miles of use. The only issues are fuel mileage hit and price of the tires, not really the tires fault for either though. When this set is done I will most likely buy the same size and model tire again. Toyo became my preferred tire over BFG about...
Service mode just means the vehicle won’t make any height changes while engaged. You can engage service mode from the center touch screen or it should auto engage when it senses one wheel being jacked up. When jacking from the frame I would actually put the suspension in off road mode, that’s...
I have used 4L in powdery sand to keep transmission temperatures down, on rough forest service roads to keep from riding the brakes and in situations I wanted maximum traction, like water crossings. 4L is the only time you can use the +2 inch setting on the air suspension.
You can google fender mod to get some ideas, Westcott Designs makes a bracket kit some people on this site have used. I attached the Cognito Motorsports guide for trimming 2019 and up 1500 series GM trucks and 2021 and up full size GM SUV’s.
I have the same tires on stock air suspension. The rubbing issue you are having is due to the wheel spacers. They are pushing the outside edge of your tire into the fender liner during a sharp turn. For reference these pictures are the exact same 285/50r22 toy at3 on a stick 2021 suburban high...
the closeup pictures in my first post are at entry/exit height (lowered 2 inches) to simulate when the suspension is compressed. The picture of the entire front wheel is at normal ride height. Tires are 285/50r22 Toyo AT3 on factory High Country wheels.

285/50r22 is the largest tire you can run without suspension modifications or fender liner trimming. When you turn the wheel hard left or right the most limiting dimension is the front wheel wells, specifically the rear portion.
I had an issue with an intermittent “service suspension system” message. I have pasted below the resolution for my issue I posted in another subsection of this forum…
I wanted to follow up for anyone who has the “service suspension system” issue in the future and the dealer can’t find any...
I wanted to follow up for anyone who has the “service suspension system” issue in the future and the dealer can’t find any stored codes. I bought a SC 530 scan tool off amazon. Plugged it in the obd port, navigated to the electronic suspension control module and observed the wheel...
Could you post some details about the fender brackets, installation instructions if possible?
I have 285/50r22 Toyo at3’s on my stock suburban and would like to attempt 285/55r22’s when the time comes for new tires. The limiting factor currently is the rear of the fender wells when the front...
The shackle bracket will bolt up, no issue. You will almost certainly have to do some plastic trimming.
Something else I have noticed that could be explored… the recovery hooks for 2023 and up 1500 trucks are longer and bolt in slightly differently than 2019-2022 1500 trucks. I am curious if...
