Car Owners Hub UK - Built by Drivers, for Drivers

My 2014 E350 convertible, which I recently bought, has the regular 18-inch five-spoke wheels (8J ET45 up front and 8.5J ET48 rear), but I'm considering upgrading to the 19-inch AMG wheels (8.5J ET44 up front and 8.5J ET44 rear). Could you please confirm whether these measurements are accurate for the convertible model? Additionally, I'm assuming that the new 19" wheels are from a coupe, even if there are 9.5 variations available for the rear. I would really appreciate your assistance.

Three remarks.

Have you looked in the manual to see what kinds of wheels and tires were standard? (You can find a tyre pressure guide beside the petrol station or on the driver's side of the vehicle, near the B-pillar.)


For what reason would you want to ruin the riding quality by shoring it up with 10-inch wheels and tires? You run the danger of denting wheels and tires.

Do you know that this and other MB models have problems with rusted subframes?

I have verified, however the results do not include offsets.

You can get away with those alloys on your coupe.
Put 255x30x19 tires on every wheel.


For your personal size reference, please go to the website below and scroll down to A/C 207 E Class.

The chart indicates 235/35R19 all-around on 8.5-inch wheels, so I don't believe you intended that. That's a really big width for the front. Rear wheels measuring 9.5 inches are required for the 255/30R19 tire size.
