2022 Escalade on order. Same setup as the AT4 in terms of Adaptive Suspension. Going with Toyo ATIII. Clearly LT285/50R22 will work, but has anyone been able to get the LT285/55R22 to work with GM Adaptive Suspension and EdgyMods?

Ultimately, I'm asking, do I go LT285/50R22 or LT285/55R22? Thanks!

Any update on this? Looking to order an AT4 with air ride but on the fence about the ride quality with the Switch or Edgy Mod lift links.

I have a Z71 Suburban with air ride.

Stock it has the 20” Goodyears. They rode like a dream. Literally unreal. Then I went to an OEM replica 22” wheel and Michelin Defender in stock size…. Ride isn’t terrible, but big difference.

I ride gravel roads a bit in height setting 3.

I know you are looking at going to a bigger tire and adjusting the base ride height up. Based on my observations I plan to go back to another 20” wheel.

Black at4 take offs in 20” with BFG’s and see how I like that.

No doubt the 22” wheel looks good with a bigger tire. I’m sure you could get yhe 285/55 to work with suspension links. I believe the ride wouldn’t be great though.

Regardless of how you manipulate the static height of the air suspension, 285/55r22 won’t work with the suspension compressed (big bump or at easy exit height) without removing a bracket from the rear of the front fender wells and cutting/zip tie the fender liner back.

The attached pictures show my 2021 high country suburban with stock wheels, 285/50r22 Toyo AT3 and air suspension at easy exit height which duplicates the suspension compressed during driving on rough terrain. You can see the clearance between tire and fender liner is minimal with the wheel turned, any taller of a tire requires fender liner mods or a lift kit that lowers the suspension components.

285/55r22 2” RC level, 1.25” bora spacers. No air suspension tho. Minor trimming was required. Rides great.

These instructions are for 1500 series Silverado’s and Sierra’s but the trimming would be similar for a Tahoe, Suburban, Yukon, etc.

Just to confirm, these pics are with the 1.25" spacers? Thinking about it...
