The E63 AMG runs the 255, but IT HAS WIDER FRONT FENDERS. Give it up man.

 

Alright well thanks for that. So in a sense, 245 is as wide as you have been able to go up front at least on stock wheel size..

Give it up?? Why? If you're tired of responding then that's on you. I'm just simply asking for advice. Some helpful advice was posted and there was also a minor misunderstanding. That's been cleared up. I never stated I was trying to look like the AMG E63....I just stated I had the AMG 18s and wanted to know how wide people have went up front with those. Once I gather a Max size from different experiences on here then I proceed to decide if upgrading to 19s would be the way to go. Really don't get the issue with tryna figure that out.
Also, you're the one that initially said you've seen 255s up front with some success....am I wrong to take that information as useful? Because now it definitely sounds like you've backtracked on that idea and that I don't understand it's because the E63 has wider fenders...

 

255’s squeaked in with non stock wheels and offsets. I don’t even have 255’s up front on stock wheels. Can I ask why you want a wider track up front? What is the purpose?

 

Well I wasn't aware of that. I apologize. All I read in your post was you've seen some make it work. Didn't know it wasn't with stock wheels. And it's not necessarily that I WANT a wider track up front per se, its more of, if I CAN then I might as well. My tires are needing to be replaced very very soon. At about 4/32" all around. So I figured this could be the perfect time to see my options. That's all. And as for why? It's just a personal look for me. Something I like. My thing is, if it's literally a wasted effort in increasing the width up front on the stock wheels? Then I don't mind leaving them as is. The only thing I came across was, if the rear won't really fit much larger tires on the OE wheels? And I have to replace the wheels? Then I might as well replace the front wheels also? See my thinking? Unless they just happen to have these wheels at a wider size just for the rear. And by swapping all 4 rims out, I might as well go for the size that allows me to have the most width without any issues. (at 18/19") if the front will only really work well at 245/40? Or maybe 255/35 then I'd be leaving them at 245....not worth it. It's mainly the rears I want to change. So by knowing what my front size will be? I can determine what the rears need to be to stay within spec to keep from having 4Matic issues.

 

Ok, understand. At least you are looking at both front and rear to get a proper safe setup. My fronts are 245/35, which is different than the stock 245/40. I needed to do this to achieve a safe setup with my 285/30 rears. Just keep looking at the total setup before you press pay.

 

just FYI, the E550 "AMG" wheels are trash. They are cast in Czech Republic, heavy and most likely out of round(mine were). Some people use them for their garden hose roll-up as they are not good for much else. I understand if that's all you have, but think about saving for some nice light roll-forged wheels. I have TSW Bathurst on my 550. Much lighter and stronger than stock "AMG" wheels, and not too expensive either, on par with most cast wheels

 

No worries glad I could clear up some of the mud for ya. Ohhhhh ok that makes alot of sense. Interesting. And that's with the 19s very interesting. Yeah I'm trying to get the whole thing mapped out so over the next few weeks/months it'll just be as simple as following an outline. No thought process needed. You got 285s in the back.with 245s up front. Works for me. Thanks for your additional input. I'll take that into consideration as well.

 

Are they really? Didn't know that. Not sure what cast in the Czech means but lol thanks for the info nontheless. I'll have to look into some then. I'll see what I can do with my current setup first as obviously that would be the cheapest route. At least....up front. If it seems as tho this would be a horrible investment? I'll have to look into upgrading the wheels and therefore just go with 19s all around. Or maybe a wider 18"? I'll look into the TSW. On my Passat I was looking at the Tracklites. Those any good?

 

I would stick with wheels that are made specifically for mercedes as they do have advantages(like the pin holes drilled through the face so you can still use the mercedes alignment sensors that align you car via the flat of the hub, not the rim of the wheel).

Ah, the Czech Republic. Formally Czechoslavacia of the former Soviet Union. Not known for their "wheel-manufacturing" prowess...lol

Take you car and have the rims put on a balancer to ensure they are straight, easy enough to see while it is spinning. One of mine was cracked and getting worse by the day. I had no choice but to buy new wheels. If you can't feel them(I could) then you'll probably be fine for at least a set of tires, depending on how you drive...

 

Ouch I suppose that makes sense lol and I suppose I could get the run-out measured. Just to see. I will say that I do feel a shuddering upon braking and a very slight shudder while driving...the driving is very clearly my tires. Must be worn unevenly or cupping. Braking could be rotor hot spots or something. Regardless...I suppose I need to know what offsets will fit up front with 18s and 19s. Obviously tire size plays a large part too. As well as wheel width. But I'm looking to move towards 9+ as long as they fit. In a perfect world I'd have 305s out back but....I man can dream lol I'd settle for 285/295 in the rear at whatever offsets and wheel sizes necessary to prevent rubbing or clearance issues. This offset thing tho. Should I stay with the OE spec? Or is negative ok also? Don't see many negative offsets on here. I'm sure I'd need about 10" in the rear...maybe 10.5 my thing is. I have no clue if any of these will even fit with a given tire. Is there some measurement somewhere that I can look up that lets me know fender to suspension clearance in front and rear so I can work the numbers myself?

 

best thing to do is to physically measure what clearance you have now with the wheels that are on it, see how much clearance there is and then use the measuring/fitment websites to figure out what you can do. Pretty sure 9" on the front is going to be an expensive, custom made wheel, if you can even fit it in there. I'm sure someone has done it, but most people don't. I know you can fit 10" in the rear, maybe 10.5 with the correct offset, but it will be very tight. 8.5ft/9.5rr is the most common and user friendly wheel sizes.

 

Ah. Well that makes sense. Damn glad to hear that and a little disappointed also lol 9in would be expensive ? Any reason why? I'm not going with that, just very curious as to what would cause it to be expensive. Not much wiggle room up there? and might as well go with the 8.5s that most go with up front. 10.5 may fit as you said in the rear so maybe I'll look into both sizes. Both 10 and 10.5 see which works best. And I was unaware that I had to measure it out myself but have no issue doing so. I just thought there mightve been a general consensus on what size to put out back that'll fit. As you said tho 8.5/9.5 might need to be my sticking point. Or perhaps 10. Especially if trying to push for 285/295/305 at extremes. Thanks for your response as well...really helped propel me in the right direction. I guess my final question is just about offset. Front offset anyway. As rear I'm sure I can play around with more. But the front seem to be very clearance oriented. Do most just stick with the stock offset? Maybe +/- 10?

 

Not to muddy things here any more, but what the hell. My front wheel is 9”. My rear is 9.5”.
These are the OEM E63 AMG 19” wheels.
I like the look of these BBS bespoke designed wheels for the E63. Since they are OEM, there are no fitment issues, other than I did not want to risk running the 255 up front.
The front offset pushes the wheel out towards the fender. It is an ET37 vs stock ET48.
The rear offset moves the wheel inward a smidge. It is an ET52 vs stock ET48. The 285 width is not a problem.
These are very difficult wheels to find and can easily cost $2500-$3500 for a set. There are cheap copies out there, but they are junk.

 

cost for 9" was considering stock E63 takeoffs or custom made(fully forged can be $2,500...EACH!) wheels, both of which will be very expensive. For instance, my 19's and tires were just over $2k for the complete set, out the door.
10" is definitely doable on the rear, not sure about 10.5 though...

 

Ohhh now it's all clicking together. Makes sense. Looks like 9in can be mounted up front but probably at a 35, instead of a 40 profile. Just to account for the extra width huh? This info helps greatly. Thanks for that. But you didn't specifically go for 9in up front. It's just what the E63 wheels happened to be. I get that. 285 isn't a problem. Good. Like to hear that. Which means there could be a possibility that I could manage 295/305 with the right settings. Especially with 285s on a 9.5. and at +52 I can look to stay around that or less.


EDIT: Also glad u posted info about the up front offset. So you can go a tad bit more negative in the front so as to not clip the suspension. You have any photos of your fronts? Would like to see your clearance. I'd probably try n stick around +37 since I haven't seen many figures on what the min and max should be when playing with offset.

 

Yikes. Looks like those won't be in play lol yeah I may go with 9.5 or 10 especially since 9.5 can achieve 285 without issues. 10.5 looks to be excessive anyway. I'll leave that alone. I'm sure on a 10" I could get maximum width. If not I'll stick with 9.5.

 

E63 AMG 19”

If you zoom in on the front you can see that the 245 wide tire on this wheel and offset is right at the edge of the fender. A 255 wide tire would poke beyond the fender. On the rear I could probably add a 15mm spacer to push the wheel further out as there is room to do that, even with the 285 tire.

 

Hmm I see. And this is on an E550 not an E63 correct? Just wanted to make sure the fenders weren't different. Yeah there definitely isn't much room up front. 245 it is then. I'll have to go back n look but did u have 245/30, 245/35, or 245/40? I'm not a fan of using spacers personally. I'd just go with a wider tire. The look of them sticking out a lil more isn't what gets my rocks off lol it's that look when you sit behind an older Porsche 911 or a BMW X6 M and you see those monstrously wide tires...even if the car itself appears unassuming. Just a personal thing...

But the fact you could probably add a 15mm spacer kinda clarifies there's possibility for 300-305mm width in the back. At least on a wider wheel. Nice setup btw.

 

Are you lowered btw?

 

No way you could add a spacer on Key's rears, no way in hell. You would need a wider wheel with less offset as there is a bit of room on the inside of the rear to go wider inside while keeping the outside lip in the same place. I mean, you MIGHT be able to get another 2-3mm out past where it is now, but I bet the tire would rub the fender lip then.

I run a 285 on the rear on a 9.5, but with more offset so I'm actually flush with the fender. I'll try to remember to post up a couple pics to show you where they sit.

I'm actually debating on either buying some 17's for the rear and getting 275/45 drag radials or just going with some Toyo R888R's in 235/35 and 265/30 on my 19's. I know the smaller diameter 19" tires would be slightly beneficial for 1/4 mile times, I'm just not sure about driving on the r888r tires daily....swap tires around all the time, or just get Toyos??? Decisions, decisions...

 

Now that def muddied up things lol you don't think he could? Really? But what I'm seeing is 285s have no problem on 9.5s. so I'm thinking I'll go with 10s then. Also I could be misunderstanding...but instead of saying more and less offset don't u mean positive or negative? And by more(positive) offset wouldn't u be less flush with the fender? I thought negative offset would look like a pot with the bottom facing the suspension....and positive would be the bottom of the pot facing outwards? Or did you mean the outer lip of the rim is flush with the fender? But I think I get what you're saying. Having more negative offset would push the rim lips closer to the suspension as it allows for more room that way...and not closer to the fender edge

Yes please post pics. That would be great.

Ugh I know. I thought about just sticking with 18s when I get wheels now....but at that width it's looking like I'll have to go with 19s possibly

 

I feel like maybe you should go with the 17s with the 275s. Daily driving will always trump what you do occasionally

 

check this out, this is the best site I know of for custom wheel fitment as it has the most variables for input. You can see Keys wheel/tire setup on the left and mine on the right. You are correct about the offset, I've been saying it backwards. More positive is further from suspension and closer to fender.

https://www.wheel-size.com/calc/?whe...cl=50mm&sr=0mm

I've set the fender clearance where mine will rub and you can see there is 17mm clearance on Key's wheel(this is just a representation since it is actually the tire on my car that rubs). So I may have been mistaken on being able to fit a spacer on the AMG wheel as I honestly did not expect that much positive offset...+52 is a lot!

 

my biggest issue with this is that I never know when I'm going to randomly meet up with someone with as much enthusiasm for killing dead dinosaurs as I have. Like they say, "If you spinnin', you ain't winnin'!"

 

Oh wow that is a nice lil site there. I'll have to play with that for a while. Thanks for the link. And I see. Yeah little mishaps like that happen sometimes. So with a much more positive offset it could probably be achieved in the rear. And if that spacer can indeed be fit on his? That gives me hope. I'll definitely have to check it out. So are you saying yours essentially only rub because you didn't get a positive enough offset?
