Hello, my w124 came with 17" monoblock rims but i just noticed that one wheel i slightly different, one is with the amg badge and is about 1cm narrower than the other 3 wheels, but the tires are same, will this somehow affect my handling or is it bad for the car?

If the tires are exactly the same and the one rim is as you say more narrow from front to back, then I would expect that tire to fit slightly differently but not noticable, especially if it's mounted on the rear. If mounted on the front you will probably notice a different wear from the opposite side tire.

So you have one real AMG monoblock and 3 reps?

My guess is the reps are 7 or 8 inch while real ones are 7.5 and 8.5 stagger usually. Or sometimes people run 7.5" square. In any case check the specs on the wheels if you want it to drive properly. I wouldn't call this a safety issue.

Karl, recommend having matching wheels on the same axle ... if not on both axles. It appears the previous owner either: 1) did things on the cheap, or 2) lacked attention to detail.

My son bought a 1997 BMW M3 that had 3 wheels the same size, while 1 rear wheel was the larger staggered size wheel. It cost him hundreds of dollars to buy another larger size rear wheel.
