SL55/63/65/R230 AMG: Help needed with wheels



I hit a pothole last night and I bent a rim and now have a flat (possibly need a new tire) and I have to try and decide what to do with the wheel in terms of repair or replacement.
I'm a real newb when it comes to wheels and tires. Can someone please give me some advice here? What should I need to know? Size, offset, etc? All I know is that I have 20" tires on the car. (2003 SL55)
Any advice would be really helpful. Thanks.
Yours will say R20 for sure since you have 20 inch wheels. Also, remember we have staggered wheels and tires so the front sizes are different than in the back.
Hope this helps.
I don't think any of the SL's came with 20 " tires, and only the 63's etc. came with 19" (e.g. the 2 piece 19" on the 2005's, etc.). Thus, I'm 99% sure your wheels are aftermarket, and the 20" is more prone to tire damage on potholes and aftermarket wheels are more prone to bending on severe impact than OE wheels.
You'll probably need to go to a wheel retailer rather than the MB dealer to try to get a replacement and keep the three you have.
OR - go on eBay, you probably can find a good deal on a set of four 18", or maybe even 19" Mercedes/AMG wheel with tires.
Bad winter for wheel/tire damage in our area this year, but not nearly as bad as last winter when the MB dealer sold over 600 tires/wheels due to pothole damage!

So, I am getting these new wheels and like I said, they are 19's so what are your opinion on tire sizes? I'm thinking about 245/40/19 on the front and 275/35/19 on the rear or should it be 35 on front and 40 on back?
The ones I'm replacing, front were 255/30/20 and I'm not 100% about the back but I think they may have been 255/35/20 but like I said, I'm not 100% sure.
I'm going to get Hankooks. I've had then on various cars for 12 years and I'm happy with them so I'm just stuck on size. Like I said, total newb with tire sizes.
Attaching a picture of the style of the new ones.

I absolutely love the wheels in the picture. If or when I change out my stockers, it would be for that look. That gun metal looks good on most cars, but seems to me would look great on my pewter metallic color.
One more thing, I need new tires this season. I am trying to decide if Michelin PSS are worth the extra money or should I just go with Hankook V12s? My boss runs V-12s on his Maserati and loves them. He doesn't lay down the torque that we do though.







The wheels in the picture (and in signature) are 19" x 8.5" Front, 19" x 9.5 rear, with the tire sizes referenced above.
(Edit : for some reason picture wouldn't attach but signature line has referenced tire sizes and this link will go to a different picture https://mbworld.org/g/picture/3294518)

Now my tire choice. I said previously that I was a big fan of the Hankook but when pricing them out, I came across the Yokohama ADVAN Sport A/S.
They seem to have pretty good reviews. Anyone used them before?



My S Class had been chewing up tires at one point because of a problem I'd been having with 4matic. Decided to buy the cheapest but reasonably rated tires I could find which ended up being Sumitomo (considered a second tier manufacturer). Although they were very cheap I ended up liking them a fair bit, so a very long way of saying price (i.e. paying more) isn't always the best indicator of satisfaction.
Not my work so a big thanks to the original author.






) refused to put them on. I think there are owners on this forum that have experience with them so would have a better informed opinion than I do.






Not to hijack this thread, I could start another and I know there are lots of tire threads on here, but general thoughts on all season versus summer? I live in Toronto Canada and would consider myself a 3 season driver. Often times early spring and late fall the temperature gets below recommended for summer tires, but since I don't winter drive this car I don't want a set of summer and a set of all season to rotate early and late in the season. I haven't experienced major issues with the Michelins I have at low temperatures but maybe I've just been lucky to date. For example it was in the 30's Fahrenheit this week but I drove my SL all week. Am I taking too much of a risk with summers only?



Thanks all.



Looks really good. I would have said silver might have been a better choice but I like this look better.
Thanks all.



Granted, I have only been driving on them less than a week but I'm quite happy. They are certainly better than the old setup I had. Just ride comfort alone going to the larger sidewall and the 19's versus 20's I had.
