I just added another AMG to my lineup, a beautiful 2016 GLE63 s. Whoever owned it had staggered wheels on it and need help figuring out the right tire pressure on fronts and backs.
Front wheels are 295/35/21. Back are wider at 325/30/21.
first question I have is, what do you all think the best tire pressure to have on the fronts and backs? Took it my local Mercedes Benz in Seattle and they recommended 40 PSI all around. I have a feeling that might not be the best set up.
second question is in terms of performance and handling, is this set up better or worst for the car? Would it be better to go back to the stock setup of 295/35/21 all around?
What does staggered have to do with tire pressure? There may be something there but I've had dozens of cars with a staggered setup and always ran high pressure to save wheels. The only time I bent wheels was when I used the factory pressures.

I'm not sure if that's necessary on the v167. I haven't read of a single v167 owner cracking or bending a rim. I have the 22s and set my pressure to just a few ticks above normal load which has worked out for me thus far.
Here's the gas door flap sticker for my 53 and it's 21 in.
Somebody can post a picture of theirs if they match the OPs, one step wider.
Too much inflation reduces the tires' impact resistance, and also reduces traction.
I don't think the forces required to break a wheel would care about an over inflated Tire (ie not protective).
IMO The cars need more front tire, not rear, so I am actually opposed to staggered setups.
I'd recommend going back to stock. Saves money on Tire rotation also.
I'm the OP on this thread, it's been a while I forgot I already had an account on here.

That's what I concluded after my research. Thanks fo that info on your 53, I got the same one on my 63 but can't go by it as it has staggered fitment and might need to be a little different. for now keeping all fours at 40 PSI until I get confirmation on better PSI numbers.

I was afraid the science might say so, good to know. These staggered fitments make the car look great and give it more muscle, but I'm all about what will perform best under high speeds and curves. Going to be looking for some stocks to go back on it next.
Thanks mikapen for the very informative and helpful reply.
MB always recommends different pressures front to back for ride quality and different pressures for different loads.
That's what I'm trying to figure out, I can propably go by what the gas stickers say for the fronts since those are the same size as the stock. Not sure what the rears should be though as those are wider and lower profile than the fronts.
Mine is a 2024 gle450 with staggered tires too. 275's in the front and 315's in the rear. I am never going to be fully loaded, usually just me and my daughter. With that said, when I got it from the dealer in July, it was running 35lbs up front and 41lbs in the rear. I dropped it to 32/32 per my understanding of the gas fuller door but immediately got a low tire pressure indication on the rear. Did I misunderstand this? Is there a way to reset the warning system? For the cost of these tires I wouldn't want to prematurely wear out the rears. I live in Florida and don't run the risk of pot holes like the northern states do. So I am not worried about the rims.

Yes there’s a way by pressing some buttons (down arrow or ok button) to set baseline range for tire pressures you want so the warning comes on when pressure is like 20% off.

The key is not to overinflate the tires but higher than recommended will give you a rougher ride but improve pretty much everything else. The higher pressure will also keep you safe regardless of weight or speed. How many say, Oh crud, now that I have five people in the car, I need to go put more air in the tires to be safe? Yeah, pretty much nobody does that. As long as you don't overinflate, the tires wear better than if you ran what is on the filler door and will be safer in a variety of situations.
