I'm planning on upgrading my GLE 450 to AMG 5-Twin Spoke 20 inch wheels & 275/50R20.

The original set is square 20 x 9J, but offset is different : Front is ET57 and Rear is ET44.

Is it possible to install all 4 with Front wheels ET57? In that way, I could rotate the tires without dismounting.

What would be the implications of doing it (besides the obvious rear wheel being more inside)?

 

I stopped doing tire rotations. Every time it's done, I get unwanted noise and vibration. I just accept that I will need to replace the tires a few thousand miles earlier than I would with tire rotation. With my 2024 GLE 450, the cost of mounting and remounting the tires every 10,000 miles is probably more than the savings from tire rotation.

 

Not an "expert" by any means, just my personal take...

GLE V167 never had any square setup for 20 inch wheels. So, technically, it will be out of spec. The exact implications are not clear. Wheel offset, hypothetically, can affect suspension - clearance / motion ratio etc. It's also not clear what's easier to articulate to tire shops - staggered setup or the fact that it's not staggered as per factory spec anymore.

Do you swap all-seasons to winters in PA? If you do, tires get rotated during the swap. We have winters for 4 months and all-seasons for remaining 8. If you use all-seasons year round, you may consider not rotating them. It looks like these days, for modern and mechanically sounds cars, rotation may not be that critical anymore.

If you inspect your tires and see the signs of uneven wear, you can certainly re-install and rotate but chances are - you have something else going on such as tire pressure, alignment etc, which you need to address regardless.

If you do want to rotate / unmount / mount / balance every time, consider added time, cost and higher likelihood of wheel damage as a part of it.

 

It's not clear why Mercedes chose different offset for front and rear and complicate things. In case of rotation, unless it's the dealer's service, the tire shop here won't know about the difference.

There's no winter here, it's summer all year (rainy season and dry season, though), tires will be Pilot Sport SUV all year. I had to rotate tires in previous all wheel drive SUV because front tires wear a lot faster than rear (turning, heavier load in front) and that gave the tires a lot more lifetime.

I have a friend (same car but 20 inch wheels) that never got the tires rotated at the dealer in 3 years.

Considering that it'd be better to keep original specs, if I want to rotate (uneven wear) I'll go with the dismount and re-balance option, as labor cost here is relatively cheap.

 

The easiest solution to run a rotatable square setup is to install spacers on the rears only. You can rotate as often as you'd like, but you will need to run different lug bolts front and rear. You'll want to make sure anyone performing tire service knows what you've done, of course. Small price to pay if you want to rotate but keep a factory offset look.
