The MB tech told me they don't rotate and contact the front struts. I searched the forums before purchasing and found that others are using the same setup. Beyond frustrating. What did I do wrong?

It is the /40 profile way to high, you can run 275 and 245 but much lower profiles, those tires will probably never work, that is like SUV sidewall these days.
correct size would have been 275/30-19 and 245/35-19

Anyone know if I can run 245/35/19 and 275/30/19 on stock 507 wheels but with 12mm and 15mm spacers aswell as being lowered on H&R springs? or should I stay safe with 265/30/19 on the rears

I'd stick with the 265s out back if you're lowered.
Yea I ordered 265/35/19 for the rear to try to fill in that 1” gap and those rubbed on the fender if i had any passenger in the back. Learned not to make that mistake again.

I was running 275s with spacers and I got a slight scrub when i would hit bumps at 60mph+ so i sized back down to a 265 especially since im getting H&R springs soon.. Never had issues with the 275s and no spacers tho.

Take those tires off and post em for sale
good to know. I thought about going to a 265/35/19 for the rear to also get rid of that gap.. guess I’ll be staying at a 30 lol.
Why do they put a “fatter” tire up front? Shouldn’t it be the other way around? 30 up front and 35 in the rear. Get some more meat back there?

30 and 35 is the side wall profile of the tyre, 255 and 275 is the width of the tyre, when you have 2 different tyre widths you also stagger the profile to get the same rolling diameter front and rear.
So 30% of a 275 tyre width will give you the same rolling diameter as 35% of a 255 tyre.
Another question I have is if I can go up a size in the rear to 265 but keep the fronts at stock 235. Any downsides to this? (Cant seem to find Vredestein Ultrac Vorti in a 245/35/19 anywhere locally and don't wanna pay duties if shipped from USA otherwise I would size up the fronts to a 245)

I run 18 x 8.5 & 9" with 235 fronts with 275 rears and no downside that I can notice.
No ABS or dash lights and have been running this setup for nearly 2 years now.
One upside is the rears hook up better than the 255 that were on it when I bought the car.
The wheels are E400 wheels that are almost identical offsets to C63 18's but with 8.5" front, up from C63 8".
So 265 rears should be fine.

I do know if you have a contact at somewhere like a discount tire or a vendor who sells your mistake tires. I have seen them able to return tires a get a correct size. I personally have tried a few different tires didn’t care for them on some of my rides and swapped them out, that includes profiles and diameter. Hope this helps
