So what are they 5x112 or 5x120 ?
Single post users seem to be trying to dump stuff here that doesn't apply to MB cars, and not know what they are selling WAY too often.
Very few wheel sellers write even a minimal information required ad.
It's so easy, but I think you're right, many either don't know, or don't have any idea what they are selling.
For the seller of these wheels, can you follow this simple example?
Fronts = 8 1/2J x 18H2 ET35 / 5 x 112 - 245/45
Rears = 9 1/2J x 18H2 ET30 / 5 x 112 - 275/40
or all 4 = 8 1/2J x 18H2 ET35 / 5 x 112 - 245/45
All these numbers are normally stamped or cast into the back of each wheel, (yea you may need to remove a couple of wheels to find out).
The other thing is the tires, try not to sell with tires if you mean to ship, tires almost double shipping and are deal killers. Selling with tires is good for local pickup only.
