Tire Pressures

So the main difference between 2500 srw and 3500 srw is frame and extra overload springs? The main springs are the same? This IS staying on the thread topic, because it relates to setting tire pressures.

I run my 2024 2500 AT4X AEV truck empty and maintain 42PSI cold all around instead of 55PSI and no TPMS alerts except in onstar or GMC app report. Please note I changed tires almost immediately (see signature) to snow/3-peak tires. Lower pressure certainly helps a little to improve comfort however theres no handling difference. I'm not a fan of the fancy multimatic suspension, I think its just a hype, others may disagree.

I agree that the multimatic suspension is all hype. It handles washboard dirt road well but anything beyond that it is lacking.

Correct. Also, the rear end is larger. I believe it's a 12" compared to the 2500s 11.5" ring gear. Front ends remain the same.
