Hello! I know this is another wheels/tires thread, but I have combed every post on the forum looking for this answer. I did read one post where I believe someone may have answered my question, but I have not heard back to confirm. I received mixed answers on the web and with MB service advisors, so I wanted to see if anyone could help. I do plan to make a more comprehensive post with wheels / tire information from this forum all in one place to help people, and to ask a few questions, but not yet. Since it's still a few months before I take delivery of my 2027 G63 AMG, I will do that later as I compile my research.

I know the G63 AMG has 20 inch wheel options (AMG Offroad Package PRO), and the spare wheel inside the carrier is 20 inches, but I am wondering if the minimum it needs to be is 9.5 inches wide with a positive 35mm offset to fit the front brake calipers? Basically, I would like to KEEP my current G550 20 inch AMG wheels with BFG KO3s on them and see if, upon delivery, they would let me switch out my new 22 inch wheels with my wheels and they can keep the new wheels for the G550 that I plan to trade... So, I am wondering if I could even do a direct swap between the two vehicles (clears the brake calipers, no rubbing, etc.)? (see information below)

Below is the current OEM 20 inch wheel option for the G63 AMG (9.5J x 20 ET 35):


These are my current wheels on the G550 (8.5J x 20 ET32), and I would actually like to keep these and swap them out with the new rims.


Below are the wheels I ordered on the 2027 G63 AMG. I like these wheels, and I know there are some 22 inch all-terrain tire options I am looking into, but honestly I would love to swap these at delivery and keep my G550 wheels above. I just prefer the 20 inch wheels I have and would like to switch and keep them.




THANK YOU all in advance, I just wanted to try to get this question answered so I could talk to my sales manager ahead of time and make a plan. Otherwise, continue my research for an alll-terrain tire for the 22 inch wheels that I ordered on the G63 AMG. I really appreciate any input!

 

Based on my own research it seems the 20” wheels do fit the G63. That said, I have 21” satin black AMG wheels on my 2024 and looking to upgrade to 22” wheels and tires. Depending on when you get them let me know if you’d be interested in selling or trading

 

Thanks so much for your input, much appreciated. From what I have seen, most of the 20" wheels on the G63 AMG have the 9.5 inch width and greater than 32mm offset, so that is what confused me about the potential for 8.5 inch width and 32mm offset actually fitting and clearing the brake calipers. I am considering trading my new 22" wheels for my current 20" wheels at delivery, so I won't have any to trade or sell if this all works. But, if I end up keeping the 22" wheels and getting another set of 20" wheels, I will keep you in mind for my set.

 

I’ve got t



hose 20’s on my ‘20 g63. It has the trail package. Considering powder coating over the chrome bits on the wheels. Anyone want to weight in on all black versus doing the chrome parts in body color green magno?

 

Thank you for sharing... Yes, those are the trail package 20" wheels that I posted above, which have the 9.5" width and +35mm offset, so I know those will fit on the G63 AMG. I was trying to figure out if the 20" AMG wheels for the G550 that are 8.5" wide with +32mm offset would clear the calipers and fit.

As for the chrome on those wheels, I love black trim, but body colored would actually look really sharp - especially that green magno (which I LOVE).

 

In my experience dealerships don’t like switching wheels even if it’s to their benefit because they want to keep the spec correct to do CPO etc.

With that said if they are willing to switch it would be cheaper to get the 21s instead of paying an extra $3,000 for wheels you won’t own any longer, but my guess is if the dealer is willing to trade they will want the 22s.

Also on the back end when you trade the G63 you’ll get dinged for not having the correct wheels on the vehicle.

Just food for thought. If you are keeping this as long as your Cruiser than ignore this advice and do what you want 😎.

If you have the room it may be better to store the 22s and pop them back on at trade in time and buy a new set of tires and wheels for your 63, maybe even the trail 20” because you know they would fit.

 

Thank you so much, buddy! You know I greatly appreciate your input, as you certainly are always such a wealth of knowledge. You bring up some excellent points and I was actually thinking the same thing as I looked at it from the trade-in value later on and just the investment in the vehicle and having appropriate wheels as part of the original factory order and specifications. If I was planning to keep the G63 for as long as my Land Cruiser (is that even possible??? - haha), then it's a different story, but I will likely do another trade in 2029 at the 50th anniversary. So, I have decided to keep the 22" wheels that I ordered with it and just do all-terrain tires on those since I know there are options at 285/45R22 that fit stock and do not rub. Depending how long I keep the G63, I will likely get a set of the OEM 20" trail package wheels to switch out sometimes if I need it - even if the wheels are a little used. I think that's the best plan to be honest, as I do really like the 22" wheels I ordered - they will look great.

My big question now is trying to figure out if I can go down a little on the width and up a bit on the diameter. As I said above, we know that 285/45R22 work with the stock 22" wheels that I am getting, but I am wondering if 275/50R22 tires would also work and not rub or cause any issues. I am saying this because they have BFG A/T KO3s available in that size, and I would love to stick to them. If not, I have ideas in 285/45R22.

I did a quick comparison of 285/45R22 versus 275/50R22 - I wonder if the smaller width (275/50R22) will fit stock and not rub? Any thoughts? THANK YOU in advance for your help and suggestions.

 

when I was researching that issue, the Ai bots said the 275’s would rub - take that for what it’s worth I suppose.

 

Thanks for the input. When I was doing some research, the AI searches (via Google) said it will fit because there are snow tires in that size that are used on G63 with 22" wheels. But, I am not really that good with AI, or trust it, so you may be right. From a width perspective, it is definitely narrower, which should help, and the diameter is a little bigger, but the overall circumference is a bit more. I know the 285/45R22 tires just ffit, but I am wondering is that the inside (width) or front to back (height)? It just seems like going down to 275 and up to 50 should clear, but I am just not sure. I am likely to test it potentially, but still have time to decide.

 

I think anything larger diameter than 32.1 from the 285/45/22 will rub without some modifications. I’m not sure if the tire is wider if that changes it.

 

Thanks so much for your input. That is what I was thinking as well, the 32.1" seems to be the limit. I have some tire options that I am exploring at the 285/45R22 size, but I may actually test out the 275/50R22 and see if going a little narrower does help, even though it's slightly above 32.1" (it's 32.8") - I just wonder if that 0.7 height makes a difference, but I may end up seeing. If so, I will certainly make sure people know there is another size option.
