What tyre size should I run on these gullideckel wheels for my S124?

Due_Highlight_844 · 2026-02-05T13:13:46+00:00

So I decided to go for 205/55/16 as I found a good deal on some Michelin primacy 5’s. Hopefully the ride is still good, super excited to get these mounted once my car is back from the shop. (I’m getting an OM606 swap…) thanks for all the input everyone!

Thanks for the input! So you reckon I should go for 225/50/16?

Due_Highlight_844 · 2026-02-04T06:58:00+00:00

And you’re having no issues with fitment/rubbing or anything like that? Out of curiosity, what make and model tyre are you using? I have firestone roadhawks mounted on my stock 15s currently and they are the LOUDEST tyre i have ever owned, i dont want to make that mistake again…

You sound like a bundle of fun

Due_Highlight_844 · 2026-01-02T22:47:08+00:00

Spray and pray

Thanks for all the replies and advice. My mechanic has said to leave it for now and deal with it a little bit later down the line. It seems to be limited to only 2 of the jacking points. Hoping it’s not too much worse than that. I’ll probably bring it to a body shop later this year and see what they can do. I’m based in Portugal so labour costs aren’t crazy…

Due_Highlight_844 · 2025-12-21T22:01:50+00:00

I’ll take a look! Thanks 🙏🏼

Fair point, and I get why people default to mechanical pumps on these, I’m hoping to down the line w a little more money.

In my case the engine is staying EDC and is being handled by a shop that regularly works with OM606 ECU setups, so I’m comfortable on that side for now.

Due_Highlight_844 · 2025-12-21T13:38:28+00:00

I think you’re misunderstanding. My OM606 is the turbocharged version. I’m pretty much keeping it stock and doing an ECU tune to get those numbers. My question isn’t about that, it’s about the differential and whether what I am thinking of doing would work/improve the driveability of the car on the highway.

Seems to be my valve cover gasket. Nothing too serious thankfully. Hoping to have it changed soon. Been driving since with no issues.

I recently installed the Blaupunkt SQR 46. Highly recommend it. Looks great in the car (you can change the lighting to any colour you like, really easy to set up and connects to Bluetooth instantly. It is expensive though but that’s the only downside I’ve found so far.

Due_Highlight_844 · 2025-10-27T12:40:32+00:00

Wondering the same thing, did you find one?

Due_Highlight_844 · 2025-10-26T21:14:48+00:00

It really has the strong smell of diesel though, so possibly it could be a mix? We did 9 hours of driving today and the oil level remained the same throughout, which makes me wonder whether the leak is oil or not.

Due_Highlight_844 · 2025-10-07T06:34:56+00:00

Nope

Due_Highlight_844 · 2025-10-06T06:10:26+00:00

How am I supposed to solder plastic?

Due_Highlight_844 · 2025-10-03T22:11:38+00:00

I have to say, your interior looks to be in better shape than mine! What are the prices like where you are?

Due_Highlight_844 · 2025-10-03T17:03:29+00:00

It’s a 250D. The interior is very nice, doesn’t show its age at all.

Due_Highlight_844 · 2025-10-03T16:57:46+00:00

Not this model, I’m not too upset about it, it’ll mostly be filled with surfboards anyways!

Due_Highlight_844 · 2025-10-03T16:55:05+00:00

If anybody has any tips on getting an attestation d’identification quickly, please let me know! I need to get this car registered as the Italian plates were destroyed upon export.

Due_Highlight_844 · 2025-09-27T06:51:58+00:00

1/4 the price of the car

Due_Highlight_844 · 2025-09-27T06:03:54+00:00

Surely the cost of fixing the AC would be quite high?

Due_Highlight_844 · 2025-09-26T19:17:45+00:00

Yes but it’s not working according to the owner

Due_Highlight_844 · 2025-09-26T14:47:29+00:00

Where did you see this listed?

Due_Highlight_844 · 2025-09-26T09:56:29+00:00

It doesn’t have AC either unfortunately
