GL450 - big improvement swapped stock 19" for 22"
Wheels are 22X10 ET50 replica AMG wheels with gray colored accents and the tires are new Michelin Latitude 295/40/22 tires.

Does anybody know if there's much difference in strength between replicas and OEM? My only worry is the replicas may be made of softer material and more prone to bending??? However, even if they bend, they are much cheaper to replace.
Simple physics, high pressure, make the sidewalls stiffer, transmitting MORE force on the rim. Lower pressure allows the sidewalls to flex, absorbing the force.
By the way, OP, how bad did it hurt the ride quailty?
I only ask as my roads are ****ty, and anything over a 19" is death here in Pittsburgh.
PS: It certainly looks MUCH better




I think this is the best 22" you can get for GL. The wheels were bought originally from Jerry at MyMercedes.com and I think he is the only guy, who can be trusted if you need aftermarket wheels for your GL. I, originally, wanted to buy the same wheels, but decided to stay with my oem 20" wheels for now and changed Run Flats to regular tires. I will definitely change 20" to 22" on my new 2014 model GL.

That doessn't happen much around here as most people have two sets of wheels. I'll be putting the stock 19" wheels back on for the winter

More mass, is harder to get rolling.








1. Are you refering to the rim actually making contact with the road?
2. Or, are you refering to the impact of the tire with a bump/ditch/speed bump effecting the rim.
If it is 1, then I would agree that HIGHER pressure would lessen this chance as the tire would not roll over as much do to the higher pressure/spring rate.
If it is 2, then you would want LOWER pressure to lessen the impact force on the rim.
By the way, I would be MORE concerned with 2 in my state

Thanks PA

Edit: In a HIGH speed impact, more air would prevent the tire from bottoming out, aka making physical contact as was stated above.
Less air is going to lesson the impact to the rim, but will NOT prevent bottoming out obviously. So I guess in a nut shell, take your pick with those rubber bands, cause either way sooner or later she will bend, IMHO.
just pick your poison as to which obstacle you plan on hitting more often.

I still say she looks GREAT

And as far as mileage or acceleration, come on she is a 5K+lb beast so who really cares, IMHO.
I do not expect a GL breaking any MB 1/4 mile records in the near future

Or 20MPG soon

PS: Love your kid in the photo as mine go absolutely nuts in the car, LOL
