Staggered wheels on e5004matic
What do you guys think about staggered wheels for e5004matic.. i asked a professional shop, they think its ok as long as i keep the air pressures the same in all 4 wheels... i got 255/35/18 in rear and 235/35/18 in front... thanks in advance for any feedback~
you can ask Luke @ tirerack in wheels and tire section too.........keep me posted if you get advise otherwise, or if you go for it...............let me know how it worked out!
or..did you make a typo with the sizes?

in the 911 the slightly larger front is deliberate to as to maintain a rear torque bias and rear wheel drive feel....until they start slipping thne the dif sends torque to fronts.
for 4 matic you have to keep them at same overall diameter. the will be some cushion in 4 matic to allow for tire wear. ie you could end up with 1/8" less tread in back theoretically......
well........i went to MB's site and built a 4 matic with staggered wheel option and it allowed it. it never allowed this to happen in past..........

On all of my Quattro cars and on this 4-Matic, it is NOT recommended to do anything else but to change all 4 wheels at the same time when you have one flat tire. Even though the system can manage a little bit of treat depth difference it WILL make you center differential/transfer case work harder or simple fail. Not to mention, the ESP sensors also read wheel velocity.
I have never just bought 2 new tires on any of my cars, but it is not recommended. Unless you can totally assure that the diameter of both the front and the rear wheels and tires (I guess tires in the end are most important) then don't do it.
If you do it, keep your OEM wheels and tires so that if you have any problem you can put them back on the car and avoid the dealer scapegoating the staggered wheels as the cause of the problem. But personally, I would not do it.

The point is that if the center differential is always adjusting for different diameter wheels it WILL wear out prematurely. This might not show up for 10s of thousands of miles of driving, but it will be expensive when it does fail.
Would you put different diameter wheels on the rear axel of you car? The rear differential is also open. Obviously a little slippage (like what would occur when a small spare tire is used) is OK and will not damage anything if done temporarily, but would you permanently drive like that?
I think that if your (other posters) ESP and other sensors are OK with a little diameter difference that is great, but it does not mean that the center differential is not being taxed in a way that it was not designed to be used.
I personally would not do it and I have given my reasons, however in this respect, we are all free to do what we want.

No matter how desperate someone at a tire dealer is to sell you something, take the above device.
If you're ever looking at a used Mercedes 4matic that has staggered tires, don't buy it.
