Rear tires ruined / fender bent

WORST WEEK EVER! grrrrrrr

My brand new, 1 day old tires are completely ruined in the rear. My fender chewed and sliced them to pieces. They are standard 275/30/19 on my new wheels, which are standard 9.5" wide and an offset of +20, only 2mm further out than stock. How in the world did this happen!!??? I am in the worst mood I have ever been in. I just want all of my mods to be done and have my wonderful car back.. :crying:

So now I have a destroyed rear bumper and tires that are undriveable. I now have a wonderful Ford Focus rental from Enterprise..

Down to business though, what is wrong?
I don't think it is the wheels or tires. They are pretty standard sizes. The only other thing is coilovers. Could the camber be off so badly that this happened? I hadn't had my alignment yet (what I was doing when this was discovered) The car is currently at THE BEST shop in Charlotte getting height adjusted, four corner balance, and alignment on a state of the art Hunter rack. The hope is that once that is all done there will be no clearance issues.

Hopefully that will take care of it and I'll have to buy some new tires.. Unbelievable.

Venting over, any condolences or solutions or thoughts?

This is one place that bent and cut deep. The tire was also cut from the top of the fender as well.

Shop called and said there is no safety issue with the tire, strictly cosmetic. But yes, that tire thread came outta no where.. :)

Man I am sorry. This really sucks

Drew,I can't believe your bad luck!!!!:sad1:
The cutting of the rear wheel can have many causes:
-are your fenders rolled or not?Have seen some M5s that don't have them rolled from the factory...
-Some tires are 275 declared wide,but are in reality a bit wider...
-alignment(might be too low)
-maybe offset of rims wrong declared(had that happen to me with same result)

I can only recommend(by going through similar) that with new rim combinations,get the car on on jack point in the front up so that the opposite side rear is full in the springs and see if it rubbs.Similar procedure for fronts....


Don't give up,brother!!!!!!!!
Even if the beast seems not to like you at the moment,bet she still loves you!;)

Thanks man! My fenders were rolled from the factory, but not all the way to the front where it got bent in the above picture..

Even if the camber was off, it'd be more negative than stock height, since you're lowering the car, meaning the outer edge of the wheel should have more clearance from the fender than at stock ride height. Anyways, from the looks of that picture, your fenders may not have been rolled from the factory as vantaam mentioned. After your alignment, see if you can get the fenders rolled flush. You won't have this problem again, and you're nightmares will be over bro. Wish you the best.

BTW, I can't judge from the pictures, but are the tires that messed up that render them unusable? That's a lot of good thread to waste...

Damn, you have some really bad luck, big guy. Very sorry to hear this. I think it had to be that your GC setup was set too low and the camber was set too low and your fenders weren't rolled all the way. What ride height do you have your GC coilovers set to? I run 13.75" ride height all the way around and run wheel/tire combos with a greater overall diameter than yours without rubbing. Crank up the ride height, roll the fenders all the way, and have your allignment done, including -1.8 camber in the rears (I think that's what I run, but I can't remember with certainty; too damn old). If that doesn't cure your problem, then either the tires are extraordinarily large for the stated size or the wheel offsets are wrong. I think those are the only variables.

The original shop that installed the coilovers had the two rear set over an inch different in height. Unbelievable. But the tire that got chewed up was the one set higher? So weird.

Fenders are being rolled all the way and height, camber, alignment, corner balance adjusted tomorrow. They will compare measurements then to what they took today to ensure no rubbing issues. What a headache..

That sucks! I feel your pain with having your beast down for a while. Might want to try this: Get a wooden baseball bat (this is sounding bad, keep reading :hihi:) and put it in between your tire and inside fender. Roll the bat along the tire, putting pressure on the inside of your fender. This will crease that inside lip up, giving a bit more space for your tire.

Good luck with getting the issue resolved.

lol who wants to do donuts in my ford focus rental!!! I am in better spirits since the tire is ok. Now just hoping the alignment, etc will take care of the issue.

its a pure tire problem.. i re-looked at the pics in the wheel gallery and those are some serious chunky tires you got there.

check the wheel tread , on the pics off your car and the car above for instance and look at the different curve off the tires on both cars.

to low it isn't for sure , im running way lower on the same size tires.

i did have a simular experience some months ago, when changing my michelins to new michelins on the stock wheels.went in the shop no probs at all, new tires on and they rubbed on the tip where the body meets the bumpertip. i just raised the suspension a cm or two and didnt had any probs afterwards.
but in your case its almost on stock ride hight in the rear .

you can camber them out but that will result in massive inside tire wear..

only right thing to do is other tires, otherwise the problem will return... maybe a contisport or a yokohama tire..those are know for more a stretch look in oem sizes..

the tip vataam5 said on jacking the car up too compress the other side is a good tip ;)
i always use my fingers and see i got enough clearance everywhere :biggrin: thats easyer then get the jack out ,


on the suspension thing that there arent set up right.. some m5 lay higher on one side so they lower the suspension more on that side to get the car level. thats pure for looks, because when you cornerweight your car it could easy be that you got 4 different settings on each corner.

dominique, I have a feeling tomorrow once the suspension is adjusted and aligned that this problem will be resolved. (i sure hope so!) I don't think these tires are much chunkier than any other 275. I have the same tires up front with spacers and no problems. I think the alignment results will show how far out of whack everything was. If the rubbing remains after alignment, height adjusting, etc.. I guess I'll be rolling out the fenders! :)
 
#21 ·
Sorry to hear of your troubles. I highly recommend you find a shop that has experience rolling fenders if you decide to keep those rims/tires. Theres a special tool for that, but keep in mind that even the proper fender rolling tools could possibly crack your paint and this is due to the person who is doing it or the state that the paint is in. Good luck & keep us posted! :byebye:

if you decide to keep those rims/tires.
This is what I don't understand. The wheels and tires I am running are nothing more aggressive than stock, +2mm for the smaller offset. Some guys on here run 285+ on their rear. I also have not heard that the Continental DW tires run wide. This causes me to believe that the alignment, height, and camber adjustments will take care of this problem. Especially since the tire that got thrashed was on the side that the height was set an inch higher than the other. The guy at the shop said himself that with the right settings there could be plenty of room, we will just have to see tomorrow..

By the way, what is stock rear camber? I'll do a search, but any recommendations for camber settings? i don't care as much about uneven wear patterns as I do slashing my tires to pieces..

And thanks for the positive words guys, I just hate to see my beast in such conditions and having been treated so poorly at a shop. :nono:

Drew, sorry to hear about your experience with the indy shop uptown....I don't think I will be taking my car to them. Let me know how EuroWerks does for you, I'm going to use them to install my clutch sometime next week. Let us know how it turns out.
 
#25 ·
They are great people and were actually installing a clutch into another beast while I was there yesterday. They have found so many things the other shop did wrong that I am very confident in there abilities. They do a lot of custom work and race prep so they understand the differences with working on a regular car and a high performance car. Thumbs up!

this happened to me once (just after PSS9 install, stock wheels) during some spirited driving on country roads while 4 up and full trunk/boot.

came over a medium crest and as the car comrpressed i heard a short high pitched ''shreek''. passenger side rear tire ever so slightly hit the
inside of the wheel well, similar to yours but luckily no damage. there was a very slight strip of rubber missing from the outside edge of the tire
but again, luckily not enough damage that i needed to replace it. hasnt happened since.

i havent read the whole thread properly yet but notice your on GC suspension. id say play around with ride height/stiffness settings at the 'shop'
until you find a happy setting. or, and i dont know much about it, roll the fenders?

ps.

Ok guys. I got my care back today from the new shop. They went through a long process to get the suspension all setup right. They evened the heights out, did an initial alignment, then readjusted the heights, did a corner balance, further fine-tuned the height, and then did a final alignment. The guy said it was original all twisted out off whack, and that upon test driving did not think it would rub at all. So hopefully this has taken care of the fender rubbing and my tire won't get sliced up anymore.

For the suspension gurus, what are your thoughts on these figures?:

I don't think anyone has yet to comment on the loading of your car. Was the car heavily loaded at the time or in the previous few days before you noticed the incident? If you had 3 adults in the back and hit a bump or were driving on a rough road it could have been the root cause. I don't see this problem just occurring out of the blue IMHO. Thanks
 
#33 ·
The suspension being out of whack was definitely the primary cause. The car had not been loaded, and the only time I heard the rubbing in the rear was over a large bump at speed. I have been the only person riding in my car. Everything seems fine now, and the alignment/height adjustments were done with weights in the front and rear of the car and gas in the tank. Crossing my fingers there is no more rubbing, and will probably take a broomstick to the fender for good measure.
 
#34 ·
Have you had a chance to drive the car under some "extreme" conditions to test the rubbing issue? I.e. drive over speed bumps, driveways, bumps, dips, etc.
 
#35 ·
When I get it back from the rear bumper repair I will test on speed bumps etc, and probably do the jack trick someone suggested earlier and jack up the front corners to check rubbing in rear. The mechanic did some of this too and said it looked fine but to keep an eye on the tire for more marks.
 
#36 ·
Forgot to mention, when I picked up the car the mechanic said the previous shop had not tightened down the rear left suspension mount or wherever the camber settings were, so there is a chance the wheel was moving all over the place and a probable cause of the tire hitting the fender..
 
#37 ·
As I was reading I was going to post to check the rear subframe asd suspension points for wear/damage etc. If things start to move around you can get contact that can not be recreated when the car is still.

I would guess that is your culpret.

Given im on stock suspension, my rear does sit pretty low, and when i have my tools in the back(75-80lbs), the rears have maybe 0.5" wheel gap. Ive never rubbed at all, fenders have never made contact to the tire and im on a 19x10.5 +15 offset with a 275/30/19 PS2.

From the looks of it too, i wouldnt say even lowering it would make a difference with rubbing because the tire is pretty stretched.

Anyways, i do know how it feels not being able to drive the M. It sucks, days seem to last forever. How are you liking the ride of the GC's? What spring rate did you get?
