Firs time posting here, so please bear with me if the post doesn't include all the info. I have 2020 GLE 350 4 Matic with stock 19" wheels. I am looking to upgrade and I really like 21" staggered set up but after reading couple threads here about 21" wheels I think it would be better to go with 20". However, I cannot find specifications for 20" staggered wheels. Based on the info from https://www.wheel-size.com/size/merc...le-class/2020/ there aren't any 20" staggered set ups specs.
20" option
Front: 275/50R20 8.5Jx20 ET55113
Rear: 275/50R20 18.5Jx20 ET42
You can go to this website and find a tire size that has the same diameter of those 21” tires front and back in a staggered setup. https://tiresize.com/comparison/. Just doing a quick trial and error and I found this.
However, what you really need to find are 20” tires that are the same diameter as your 19”, while also being of equal diameter front and back, otherwise your odometer will be off quite a bit.
GL 320cdi, Chevrolet Avalanchero, GLE 350 (on order)
If I was going to do this I would go with the OD of the factory 21" stagger set-up rather than the OD of the 19s. I seem to recall that the 19s (not avialable in my market) have a smaller OD than the factory 20 or 21 which are closer to each other.
I personally wouldn't go with a non-oem staggered set-up on an AWD car especially one under warranty. Maybe get wheels that accentuate the front/rear offset difference better like these (which I ordered) not sure if you can get them in the States. They have a steeper "dish" look than the AMGs. They are non-staggered 20s.
Good luck either way.

Thanks for the reply. I have the exact same car and I would like to get larger wheels than 19". 21" wheels seems too problematic from perspective of getting them, installing and sounds like drivability gets worse. However, I do like look of staggered set up and hence why I thought I would go with 20" staggered instead of 21". I've replaced the front grill and also got illuminated emblem but those 19" wheels look way too small for this car. I might just go with 20" square set up since I do want to get rims in gunmetal/gray color to match the cars color.
Yeah I agree going with the larger diameter, equivalent to the 21”, would look better, but your odometer is going to be off. You can enter in the 19” and 20” tire size on the website and see how much it would be off.
The next step are finding wheels that can properly fit the car while being of a width suitable for the chosen tire sizes.
Thanks for the reply Frenetic. I was hoping someone have already tried this, so I don't have to be a guinea pig That website has tons of information.
I know front size should be 275/50R20 with rim size 9Jx20 ET57 since that is standard 20" square set up.
Big question is what to use for rear. Rear one should be 315/??/R20 with rim size 10Jx20 ET?? (all question marks are unknown to me). 11
Actually 315 tire will most likely need minimum of 11inch wide rim. Going from 9inch wide at front to 11 in rear might be too much of a change and it might look weird. Or maybe even better

You have some tolerance on wheel width vs tire width. There are charts available like on discount tire, I picked up a sheet last year. IMO, the actual staggered look is not nearly as noticeable as the wider tire in the rear. I run 20” square in winter vs 21” staggered in summer and there isn’t enough difference in the ride to notice…if you keep the tire pressure at the lower spec on the 21”s. Rather than create a non spec setup I’d go with the OEM type 21 sizes or go square with 20”s that will be cheaper with more tire selection.

I was wondering if anyone tried 20" staggered set up and if they could post their specifications for rims and tires.
You can 100% safely use 265/50-20 tire on 8.5" or 9.0" front wheel with 295/45-20 tire on 9.5" or 10" wide rear wheel. While these tires' diameter (30.5" front/rear) is slightly less than stock's 20/21 (about 30.8" to 31"), the load of the tires is more than enough for 167 GLE 350.
Finding matches front and rear tires and (aftermarket) wheels IS the problem.
Thanks all for the info so far. Main reason why I am exploring 20" staggered option is because 21" staggered wheels are mostly OEM style. I want to go with different style of the wheels and have them in gunmetal/gray color to match the color of the car to combat MB notorious brake dust problem. Based on the above reply from threeMbs it sounds like I could look for something like this:
Front Tire: 275/50R20
Front Rim: 9Jx20 and get offset close to 55
Rear Tire: 295/45R20
Rear Rim: 10Jx20 with offset some where in the mid 40s
I don't haul anything heavy with this car so I am not worried about the load as much. I am not sure how much of a problem is a deviation in offset though.

Well, 275/50-20 front & 305/45-20 rear; 265/50-20 front & 295/45-20 rear. I would use the later combo because it is probably easier to locate matching tires with correct width wheels.

That makes sense. Also confirmed with site https://www.wheel-size.com/calc/?whe...cl=50mm&sr=0mm
Looks like I can do this as long as I am able to find staggered 20inch wheels I like with 20x9 and 20x10 set up.
Off to hunt for wheels. I will post updates as I find something and eventually pictures with the new set of wheels if I get lucky.
*Edit: Adding picture of the clearance from the site Front: Left side is OEM tire 19x8. Right side new 20x9 Rear: Left side is OEM tire 19x8. Right side new 20x10
@Ocecci just be aware that that site may not be accurate for all tire manufacturers. The tread and section width can vary, even with the same tire size.
You won't know for sure until you're mounted and check suspension travel at all steering angles.
You're probably OK, but check to be sure.
Another option is a square setup but staggered offsets. It's what I did with my winter wheels and tires. As with a staggered setup, I cannot rotate my tires unless I'm willing to dismount them from the wheels. (For the record, I am not. I will run the same wheel/tire on the same corner for the life of the tires.) But it solves the problem of finding the correct true staggered fitments.
Mandrus Otto 20x9, ET45 on the front and ET25 on the rear. Tires are 275/50/20.
If you are looking to not change the tire diameter in order to avoid reprogramming the speedo/odo, this size should work:
255/45 R20 front on 20 x 8-9.5
285/40 R20 rear on 20 x 9.5-11
That will be closest to you stock 19s and gove you a nice look and stagger.

off set is my biggest problem when searching for the wheels even in 20" size. They rarely have +50 offsets as recommended by Mercedes for rear tires. Looking at your spec you went with 25 in the rear and I am assuming you don't have any problems, right?
@BenjaminKohl speed deviation goes up to 4mph when going over 75. In my opinion that is negligible difference since 65mph is the highest speed limit around me. I usually go way faster but at that point those 4mph won't save me a ticket. I want to go with bigger diameter as currently wheels and tires look way to small for this beauty.

No problems at all, but I do have the extended AMG flares. The "poke" is so similar to the factory 21's that the difference is imperceptible. (4mm more inset on the rear/1mm more inset on the front if I'm not mistaken.) I don't know if it'd be too much on non-AMG models, but it's very possible Mandrus have another setup that will work. Below is a link to their fitment page. As I recall, there are some fitments available that aren't shown. I can't remember where I saw the full list unfortunately.

Cool! we will soon have the same car, then. I don't think those staggered offsets I ordered look too bad, plus only the machined trim is silver, the rest of the wheel and inside is black powder coated to make cleaning easy. I hate to say it, but anything will likely be better than what is on yours now.
I have to say again, though, especially with the fixed 50/50 awd in the 350, I wouldn't start with staggered profiles and stuff. A guy I worked with started down this homebrew stagger path (I gave him the same warning) on his Porsche and he could never get it to drive right. I don't know if it was the sidewall flex difference or whatever even though all the offsets ODs and stuff were "correct". The traction control and stability control kept coming on at weird times, like hard cornering or bizarrely costing to a stop. Even tried different tire brands, and mixing them up to try to get it to stop. Swap wheels back to original, all fixed. The wheel guys blamed the tire guys and vice-versa. This guy had just sold his NYSE listed company so he had time and money to dick around with it and he sold the car, wheels and tires at a loss to let someone else try. I don't have those same resources, so I won't be experimenting with non-proven staggers. Funny thing, there were guys all over Rennlist claiming it was working for them, so take any advice you get as anecdotal only and might not agree with your car/conditions.

That actually is a huge difference. I would highly recommend reprogramming your Speedo and odo. Don’t want to be in any deep doodoo about your car mileage.
Man that looks proportionally correct with the AMG flares, nicely done! Looks very appropriate for winter. The raised MB center cap really pulled it off too. Where did you get the center caps?

The center caps are from ebay. Mandrus wheels are designed for Mercedes, so any 75mm Benz center cap fits. I have Mandrus winters on the GLC with the same center caps.

No good ones. Just this ...
Guy, those 25 offset on the rears are just perfect but I wonder if it will rub on the flares when the suspension bottoms out. Have you checked this?

I did not bottom the suspension the first winter, but I'm not expecting any problems. The overall diameter and poke are a near identical match that of the stock staggered 21's.
